My friend has BC on his E39 M5 and he tracks it (is actually an instructor too) and it works for him.

TRUST IN STANCE SUSPENSION! I have for the past 6 years and will continue too with the Stance ProComps I just recently picked up. You dont have to be a professional to tell the difference between megan/ksport/BC and a GREAT set of coils.

ive ran my gr+ pros for almost 3 years at a ridiculously stupid ride height and drooped springs and they just take it all day. i recently just picked up a set of PBMs for my other car and im very impressed by the build quality for the price and like the fact that they have a lifetime warranty

BCs Megan, CX racing and all those are virtually the same and are all made in the same factory and i would personally never buy them

i cant really speak for d2 or Ksport

 

PBM has a lifetime warranty?

 

i just bought some BC BR's with 10k/8k swift springs, ill have them in about 2 weeks as there being valved right now. i did some extensive research on what coilovers to get and BC's are the best in their price range. i ALMOST got the PBM pro's cause they would have been about the same price but decided on the BC's because ive heard from a few people that the PBM's suprisingly enough arent't that "angle friendly" when it comes to knuckle modification and steering angle kits.

by the way, BC's are completely different than Megan, Ksport etc... the quiality is faaaar better. Just about any coilover in the 900-1500 price range are made down the street from each other. quility is what counts, not where its made.

 

i have pbms and have a ton of angle. A TON. coilovers dont have anything to do with angle mods.

Also what valving did you have them do?

 

It's funny that you say BC is completely different than Megan, because they are completely not. While the BC is considered a "step up" in some sense of the word, they are in fact Megan coilovers.

 

when i bought my abercrombie knuckles, i told him that i was planning on getting the PBM pros and he told me that they are not "angle friendly", as thats what he had with his 72 degree knuckle and he had to do extensive modification to make them work with the pbm's.

think what you want about BC's. if i thought they were anything like megans, i wouldnt have them.

 

Abercrombie dude is wrong

 

i have personally ran Tein super drifts, stance gr+, bc, and now i have a set of apex'i ex-v's (their most sold model for other chassis, they are in developement for FC)

Tein: these are ok, very soft, great for street use. these are definitely not for someone who wants to be slammed. great for a DD that see's occasional track use

Stance: I loved these at first, but after experiencing other coilovers and having my set of stances not only rust to **** but freeze in place, I have nothing good to say about them. they go low, super stiff, valving isn't very good. not recommended.

BC: i was very surprised with these, the valving is actually very good. great adjustability. work well for either DD or track cars, but I wouldn't recommend them for a competition car. the valving is better than stance by far but I was unable to get as much grip out of them as the next set.

Apex'i EX-V (in development): I had a set of these on my S13 in the past, and absolutely loved them. after begging and pleading with apex'i, they're finally workin on a set for the FC. the set I have are still in "testing" phases but so far these are HANDS DOWN the best coilovers I have ever used, period. valving is amazing, adjustability is huge. you can turn them to full soft for the street and get an almost stock like ride, or (just for ***** and giggles) turn them all the way stiff and the are extremely stiff. I would recommend theses for both street and track use. I've been able to get a bit more grip out of the car over the BC's, and then drive the car home without shaking my fillings loose.

the apex'i are in development, but they will hopefully be available for sale at some time this year, and they will be in the same price range as bc/stance/etc, retail for ~$1300-1400

 

Were the Stance GR+ brand new or used when you installed them?

 

I need to spend more time in the "grip" section of the forum, but I am kind of an everything guy when it comes to driving my FC.

Suggestions on a coil over setup that I can:

- setup up one week to do grip racing and time attack type stuff
- and the next week setup the car to do drifty shenanigans

Been reading and gaining a great deal of knowledge on the later of my two driving types from this section of the forum. If anyone has some input that would be great. Bear in mind, my fc is my track car for the most part only. occasional street.

edit: did not mean to thread jack....

 

The difference between a drift setup and a grip setup isn't just the coilovers, it's shock profiles, spring rate balance, alignment, and most importantly, differential settings.

You can't change back and forth to a perfect setup for both without hours and hours of labor.

The best thing you could do is install adjustable sway bars, have a couple sets of springs, and simply have a diff and shocks tuned to be OK at both. Also, you will need tools to measure the alignment because you would have to do a lot of alignments...

 

for the coilovers i discussed all were bought new except the tein's were recently installed when i bought the car. i owned each of these coilovers for at least a year, with a lot of daily driving and seeing the track at least once a month (more in the summer) for the NW's 7 months of drifting season lol

and i was talking to a guy recently about the apex'i, and he wanted to see shock dyno charts. i asked them for some stuff to post up, which they will be emailing me once they get them from Apex'i Japan

 

i actually ending up going with D2 RS spec's. for the price and customer service i went with and reviews from other people they seemed most logical for what im trying to do with it. and theres also a d2 plant 15 minutes away from where i live in chapel hill lol

 

wut? D2's plant is in Taiwan, dude.

 

Archaphil - I think like valkyrie said. there isnt an easy way to have a perfect setup for both.
I personally think it is more about your alignment than your coilovers. but I dont do road racing or any of that. I rarely drift too so take that for what its worth.

 

D2 is made in Taiwan(or something), but they are based out of N.C. It's on their website. I'm guessing that's where they would do re-valving and what not.

If you want something that can maybe be doable for both drift and grip, I'd suggest a shimmed clutch-type LSD or a torsen/gear type, and some rack spacers for a little bit more angle. Coilovers, you'd want to get something that's known to do good at both sports. D2, Megan, Stance is what comes to mind.

 

Thank you for the input. I knew alignments would be way different for each. I need to spend more time reading the suspension threads on good setups for spring rates ect ect. Time to do more reading.

Seems most of you are running the ol 8k/6k front/rear setup for drifting.


cheers

 

Just buy some regular (street/track) coilovers and change the valving and spring rate (you can leave the front alone and change the balance by using stiffer or weaker rear springs) to suit your preferences.

D2 might have a shop and an office in the US, but it's still a Taiwanese company. But considering you probably can't even get Japanese coilovers rebuilt in the US anymore, you might as well get whatever can be revalved here. Japanese coilovers are overpriced anyway.

In reality the best thing for the money is using sleeves, camber plates, and rebuildable Bilstein or Koni shocks in the stock struts... the only disadvantage is that preload and ride height aren't separately adjustable.

 

i ran Stance GR+ Pros, and i loved them

 

As far as im concerned, all those brands are junk besides the Teins and the Fortune Auto's. None of those companies has real shock dyno's or says anything about the dampening. The absolute main part of any race purpose suspension is the shock and none of those China/Taiwan junk shocks are a properly built shock. Im personally going to run the Fortune Auto's. Heres why...

apex'i and tein both offer rebuilding in the US

 

Apexi's English website doesn't mention overhauls at all.

And some Teins have to be sent to Japan for rebuilding.

But that's just what the website says. You never know if it's true or not. They might send all of them to Japan now.

 

apex'i and tein both prefer users go through distributors, which is why it may not be mentioned. both are rebuilt in the US, tein never sends coils to japan since it's not cost efficient. if they do not have the parts needed they may have to order from japan, but i know apex'i stocks 99% of the parts needed, chuck at apex'i is the man!
