More pics/info on AWR and Iscracing suspension setups?

I'm looking for more info on above setups? There is limited info and from the looks of the pricing there around the same or if maybe cheaper then the Japanese coilovers.


A pic I found of a Iscracing setup:




Looks like the AWR setup can be revalved for different springs rates, but what spring do you use? Eibach/Ground Control springs?


What is the pricing like if anybody has had either setups?


Edit: I see that you can buy universal type springs: http://www.tripointengineering.com/i...cbe1838f2c93de

And therefore you don't have a set of "C/O's" so why even bother?

Here are a few options - take is as you will.

Eibach Springs & KYB Shocks - No height adjustability, shock dampening adjustability but personally I outgrew the Eibach spring rate in N/A form. I had enough traction dialed into the rear of the car (& enough HP) that if I mashed the gas to early upon exit the nose would lift and I would understeer. Good friend of mine observed the same thing in his car as well. I think this combo leaves alot to be desired for someone who knows how to set up a suspension and drive competitively. Just MY opinion though.

$343 - KYB Front Adj Shocks
$260 - KYB Rear Adj Shocks
$300 - Eibach sping Kit (By far the stiffest too)
$903 - TOTAL

Ground Control setup with Eibach RACE springs (VERY different from the kit above - choose your own rate) While you can get really aggressive spring rates, you are limited to the shocks that you can run. While I've heard many good things about the GC kit, I've heard equally bad things as well. You are limited in shock selection here bacuase the Ground Control kit is designed around the stock shock so you need a stock replacement shock. I have my doubts about these shocks being able to properly dampen an aggressive spring. I feel this is a somewhat limited approach.

$300 - Camber plates
$410 - Collars, Sleeves, Rings & Eibach "race" springs - you pick the rate
$343 - KYB Front Adj Shocks
$260 - KYB Rear Adj Shocks
$1313 - TOTAL

The AWR route. AWR's products speak for themselves I believe. Everything is interchangable and if you spend enough money you can get some adjustable shocks as well. Something like this allows you to revalve your shocks, change your spring rate, change your ride height, change your corner weighting etc etc etc

FRONT -
$240 - Camber/Caster Kit
$366 - Re-Valved Koni Shock - $183/ea
$350 - Strut Housing Kit
REAR -
$360 - Re-Valved Koni Shock - $180/ea
$340 - Shock Housing Kit
$1656 - Total

Aftermarket C/O kits - take your pick. Personally I beliece that spending anything over $1656 for a C/O kit is a waste of money. I would rather have the above than a C/O kit BUT for me I would be spending a total of close to $2,000 for the AWR route after shipping & tax. I can get a set of Stance GR+ Pro's delivered to me for $1230 (62%) of the cost of the AWR route & I have shock dampening adjustability. Obviously this is the route I'm going to take. I'm not racing enough nor competitively enough nor am I THAT good of a driver that the extra expense is worth it to me.

However - All of this is a waste of time and money if the rest of the car isn't dealt with first. The bushings, the sway bars, the DTSS, sway bars, end links, stiffen up the chassis a little etc etc make the car capable of responding to the little differences that changing an adjustable suspension will make. It doesn't matter how much rear camber you take out if the swing arm is squirming around changing your setting under load does it?
)
My only disagreement is that you can run revalved Koni's/Bilstein's with the GC kit as well. The cheap way is just to run stock Koni's/Bilstein's.

710 for the Kit + Camber/Caster Plates
630 for the Koni's
390 for the Bilstein's

Add an extra 600 up top on the Koni's for a revalve @ $150 per shock
Add an extra 1200 to 1600 for the Koni's for a revalve and adding an additional adjuster @ $300-$400 per shock.

Add an extra 260 up top on the Bilstein's for a revalve @ $65 per shock
Adjustability must be custom done, but you can do it using their PSS9 rebound adjusters + Penske/Ohlins remote reservoirs with compression adjust.

Total Prices of the GC/Shock method:

Cheap way:

1340 for GC/Koni
1100 for GC/Bilstein

Revalved Shocks:
1940 for GC/Koni revalved
1360 for GC/Bilstein revalved

Revalved/Double Adjustable
2540-2940 for GC/Koni revalved + double adjustable
??? >1360 for GC/Bilstein revalved + double adjustable.

The advantage of Koni over Bilstein? The **** thing in stock form.
Advantages of Bilstein over Koni's after full custom work? Same level of adjustability with a remote reservoir to boot!

Seems to me, the middle of the road revalved GC/Bilstein is the most cost effective race coilover setup.

The disadvantage of GC/Koni vs. AWR/Koni? Cost, even though AWR will run the Koni race cartridges, after a revalve, they're functionally the same thing. (Both twin-tube with one adjuster)

The advantage of GC/Koni vs AWR/Koni? You can piece-meal the setup, i.e. you don't have to drop all that money right away. In my case, I've been running on Koni/TII springs on one of my cars and Bilstein/GTUs springs on the other car. I can always upgrade them to true coilover if I wanted to via a coilover kit and a revalve. I've just spent money on the shocks first, and can enjoy them for the time it takes for my budget to get ready for coilovers.

Those AWR strut tubes are going to be a lot tougher for those who like to jump curbs at the track, that's the main advantage there.

Bilsteins are a better shock than Konis, they just lack the adjustments, and from what I've read their adjusters aren't really all that good anyway. The konis won't need a re-valve if you keep the springs under about 450lb/in in front and 325lb/in in the rear. The Bilsteins will need a re-valve for anything in a coilover type rate.

Those rears on the ISC kit use Delrin bushings and have lead to the rear lower mounting eye breaking off on at least one occasion (it needs to be able to flex a bit). It was documented here on the forums.

What are your goals though? If you let us know then we can help.

not trying to jack the thread but have a question, was wondering what is a great coilover for just track use. i always see people asking for street and track, im just wondering about straight track use, was looking at the tien RA *think that what it is* and wondering if any one used these before

The Koni's adjusters aren't so bad, just ignore the 1st and Last half-turn and you'll be alright.

You'd probably have to dyno-match the Koni's first with the adjusters and make sure they're properly set.

What do you think I should do for next year? GC kit is certain, but I have a choice between my Koni's stock or getting my Bilstein's revalved. Budget, of course, is a concern. Thinking about running 425/300 on my car.

If you have to revalve the Bilstein's for coilover rates, it ends up being 1340 for the Koni's and 1360 for the Bilstein's. The problem is, I've already bought a set of the Koni's so they're a sunk cost for me.

um.......nothing Japanese.

EDIT: Nothing japanese under $4k, I'm thinking Amemiya's Quantum damper?

I was completely unaware of that. GC last time I spoke with them (granted this was two years ago) was unable todo that. I was looking @ ~$2,000 for the AWR setup.

Seriously though, unless it's a dedicated track car or someone has some really deep pockets, who would do this for a dual purpose car? Who can really take advantage of a setup like that?

I called them and made sure that Koni's/Bilstein's will work. I came up with these sets after reading Dennis Grant's AutoX article. Fine piece of reading that was.

Who is Dennis Grant?

Auto-x & street use is my intention. Keeping the price as close to $1300 as possible is a muct as well.

Edit* - I was told by the shop I was dealing with (who is a Koni distributor) that they can custom order the shocks. Meaning that there is no revalve charge but they are more expensive than off the shelf obviously

You'll love this then

Do you already have any pieces of the GC/Shock kit that I posted up? if so, that'll lower your cost a little.

Ah yes - I have read that. Damn good bit of reading indeed.

I don't have any pieces of anything right now actually. I sold my Eibach/Tociko setup ~ 9 months ago and the car has been on stands ever since. I'll be treating myself to suspension for the holidays but am very torn. Really like the Stances and the service and the level of knowledge they had and @ 62% of the cost of the AWR, I don't think I'll be able notice the difference. I haven't autocrossed in YEARS and am afraid that I will have spent more money than my abilities can handle

EDIT VV I really need to stop post editing too

I really need to stop post editing.

EDIT: I would run dual adjustable shocks, just because I'm building my car up to a track car spec. Also, I think it's the best bang for the buck way of having a really good custom coilover setup.

Kudos for finding cheaper Koni's. I just didn't have all that money to drop right away, so I enjoyed my Koni Yellow's/GTUs Spring combination this year. Finished pretty high in my regional class this year starting midway through the year. This was on a stock port NA in a club where courses were designed for horsepower, R-comps were legal and I had on street tires (Bridgestone Potenza RE-01R)

RE TitaniumTT's EDIT: I think it's interesting the DG runs suspension position/velocity sensors on his car. He really does believe in tuning on the dyno, as opposed to the driver. I somewhat agree with that statement, since you can set the car to have optimal grip (not necessarily maximum) in all situations, and have the driver adapt to it, rather than giving a comfortable, but slower set-up to the drivers.

Maybe that's why I'm a fan of Bilstein shocks. I switched over to Bilstein/TII springs midway through the AutoX season.

I think there is the difference between us.

You auto-x regularily, I don't nor have I for years. You are building a track spec car, mine will be dual purpose although the roads where I live are AWESOME. & I dare say if you finished high and under those circumstances, you are a better driver than me and would be able to take advantage of a setup like that . Me dropping that kind of cash now would be like giving a midget a bazooka to kill a fly. I hope to outgrow whatever entry level coilovers I do end up with and will honestly probabyl start collecting parts soon after buying whatever I do.

I can see the whole different strokes for different folks thing. I guess for my goals, this is the cheapest way to achieve it. Though, when I make bank at work, I'm definitely opting for Penske quadruple adjustables!

EDIT: I used to work in North Greenwich by the NY state line, I would spend time in Greenwich and Stanford. Too bad these days I work in downtown NYC. You should consider coming to the MotorsportsNE autocrosses next year. Great group of guys, cheap for the amount of seat time you get. I do their autocross schools mainly for the seat time nowadays. I used to do it as a rookie, but I have had an instructor sit in my car for awhile. You pay $120 for the whole day and you get 30+ runs in the morning, plus your 8 competition runs in the afternoon. Good deal in my book!

http://www.motorsportsne.com is the website you want. They hold their autox's at Giants Stadium and their Time Trial days at Poconos International Raceway. Both count towards the championship.

Be careful with the coilovers... My friend used to have some megans on his S13 and that car was an absolute bear to drive well. A short time later one of my friends with a DC teg picked up a koni/GC setup, and that car handled like a dream. Similar spring rates on both cars. The megans just never seemed in step with the chassis. I got the chance to drive both cars back to back at a test-n-tune and I absolutely smoked the S13 (with an RB20) with the teg, even with my limited knowledge of FWD dynamics. I am in no way a great driver, but those are my impressions.

I know that stances =/= megans, but really how different can they be for about the same price? I wouldn't expect any miracles.

I don't know what a teg is, and I've called Megan and they seem like they wouldn't know a shock from a steel tube... sorry. One of the reasons I like the Stance's is becuase I can swap spring rates and get shocks revalved. I don't expect them to handle silky smooth but at least they'll be a step up from my last setup. That's what I'm looking for, a step up from the Eibach/tockico setup I had. Am I going to jump from A (stock) to B (Eibach/Tockico) to G (revalved adjustable Bilstiens and GC) - No. Not only becuase of cost but becuase I have alot more learning and adjusting to do and need to get some seattime to get the chassis back in-line. I'll be going from a ported N/A to a twin turbo 13BRE that I expect will put out 350+whp. I have alot of time before I can take advantage of a suspension like that. When the time does come I can sell the Stances and get some money back and then step up again. It would be like going from A->B->D->G

Roen - Thanks for the link. I think I will definately have to come down. If you want I can get you intouch with the shop that I was going to go with for the AWR stuff. They're in MA. They are a pro race shop that specializes in FC's & Miata's

teg = Acura Integra

DC teg = The Integra with the 4 pimple headlights.

You know, DC teg is confusing if you know about the JDM Integra's as well, both the DC2 (NA: Integra) and the DC5 (NA: RSX) are both Honda Integra's in Japan. But, I think I get what you're saying.

ITR = Integra Type R

It's alright, I think I'm pretty set with GC since I already have both the Koni shocks and the Bilstein shocks. Thaks for the offer, though.

I wake up and there is to much info to understand. LoL..


This will be for a dual purpose car also. Mostly street and light drag/roadcourse/autoexe. I want to get something that has adjustablility and something that I can change around later down the road if I have to. Thats why I was looking into those kits above. I love the simple fact that there is a ton of different springs with different spring rates and you just have to get the struts to match.

Depends on what you want. Are you an all-out dedicated racer that will stop at nothing to win? Then I suggest you get the bilstein shocks and adjust them by taking them off your car, cracking them open and revalving them on the spot.

If you're just a general hobbyist who likes a little bit of **** action to adjust your shocks and is mostly street, a cheap GC/Koni setup is 1300+. There are cheaper basic street coilovers that aren't that great and/or don't have an upgrade path to them, besides buying new coilovers. Megan, Stance, That new guy that's advertising in this section, TEIN are some to name a few.

Most American shock companies don't have standard production coilovers for our cars; you need a coilover kit like the GC or the AWR ones to convert them as such. However, the American shock companies do seem to outperform the Japanese ones.

The reason why I like American/German/English shock makers? Their adjusters independently adjust compression and rebound, without crosstalk. That way, if I want to slow down my rebound, I won't also be slowing down my compression as well! You can't really do that with the basic coilovers.

I'm going to come in to say that the Tein Flex is a very good deal for an entry level coilover. They're a very popular setup for dual duty street/track both on this and on other forums, the Miata.net forum in particular. I use them on my FC, my dad uses them on his Miata and many of the local autocrossers run them as well, and for good reason, they're good coilovers.

They dyno quite well, they're durable, they've got a good range of adjustment, they've got seperate shock body and spring preload adjustments and they're rebuildale/revalvable in North America.

If you don't already have some Konis or some other adjustable shock then you should seriously consider these, they'll run you about the same amount of $ as Konis, GC's and camber plates while giving more features.

Here's a shock dyno of one.

Do you have the other corners' dynos as well? Post em up! Also, it says at the top that the shock was re-valved. Two questions: is there any before/after data, and who did the re-valving?

I've got a number of them, that was just one of the clearer ones that showed all the adjustment range. I've got 2 others of that set, the re-valve was done by Tein NA I do believe.

I've attached the rest of that series and a few other representative samples. I've got a whole folder full of them and can post them all up if people want them. I got them off of the Miata.net forum where one of the members had some dynoed along with some Koni Yellows.
