Hey guys I've got some Eibach springs from Pettit racing, I think they are progressive rate. Anyway, I need some new struts and was wondering what you guys suggest. I want something adjustable since I drag race and will be doing some road/autocross racing. I'm also still on the stock wheels for now.

I did a search but came up empty handed, also all the threads that came up were over a year old?!?!?! Thats wierd

Any advice is appreciated

You can't go wrong with the Koni yellows. They are single adjustable (adjusts both rebound and compression simultaneously) and are fairly inexpensive. The softest setting is supposed to be equivalent to stock shock valving.

ya koni yellows or bilstein upgrade are the best. The Eibach pros are progressive.

BTW, Koni Yellows are single adjustable. They only adjust rebound. If you want adjustability for both rebound and compression, you'll have to go with the Koni Reds. A little bit more expensive, but far cheaper than, say, buying the Advanced Design double adjustables .... ouch, $400 a corner.

The dampening on the Koni's is very linear. Great auto-x shock ... almost everybody I run with uses them. They hold up pretty well on Solo I tracks too. On the stiffest setting, the ride will be rough on the streets. On the softest setting, the ride will be slightly rougher than the stock R1 Showa shocks ... or a little rougher than that, if you have a Base, PEP, or Touring model. Best bang-for-the-buck, IMO.

RedrotorR1 - I just looked up Koni yellows and they said they DO have adjustments for height but they didnt say anything about compression (stiffness). Unless I dont understand you, your saying they are compression only and I'd need the reds to get both.

If you look here they do adjust for height....

Does anyone know if they are ALSO adjustable from the compression and if so how many settings is there???

Thanks,

I have the Bilsteins and the ride is about the level of an R1 shock on smooth roads. They auto adjust when you get aggressive. I highly recommend them. Also "Bucrx7" is selling a brand new in box set for a great price. These are the most popular upgrade shocks with the BMW guys.

Yea, I though about those but i really want an adjustable strut since I drag race and road race. I want to be able to set up the rear to be pretty soft when drag racing.

If the Koni struts are adjustable for hight and compression I might get those. I also thought about the Tociko 5 ways, it seems like a lot of people run those.

I see your point but the koni's will only go so soft anyways. Your not going with a drag only type shock so its not going to compress like you think. I suggest going with a fairly soft spring, progressive type like the H&R's. They are softer up top so they will help squat the car a bit more than a higher rate spring during drag racing. A blown out shock or a drag type shock will cause some serious wheel hop drag racing with street tires on the FD. Unless you plan to use wrinkle walls. I have tried 3 different spring rates with my Bilsteins. HKS progressive, H&R progressive and stock touring springs. I like the H&R's best for weight transfer as well as ride quality. They dropped my car a bit lower than my wheel/tire combo would handle so I had to go with the HKS springs. They dont lower the car as much and are a higher rate spring. I was looking to keep my front tires from rubbing. After all was said and done I like mono tube design of the Bilsteins. The Konis are great struts as well but I think you might need to remove the rears to adjust them so thats not much fun. The Bilsteins are autoadjusting and will do what you want them to do. But no shock/strut is a true duel purpose unit i.e. Drag and Autocross/road race.

Koni Yellows will primarily adjust rebound, bound is changed ever so slightly.

Now the Reds from what I understand can only be adjusted by removing the shock assembly. I don't believe they are externally adjustable.

Let me give you the straight poop. Koni Yellows are single-adjustable, monotube-design dampeners. They adjust rebound ONLY. The adjustment point is on top of the tube, which is done with an adjuster **** (kinda like a water spicket). Very easy to do and does not require the removal of parts to make adjustments (except for the strut tower covers on the rears). Koni's come with a 3-setting mounting perch which allows you to adjust ride height by selecting the mounting perch position. This is not an "on-the-fly" adjustment; you must remove the shock to re-mount on a different perch position to change the ride height. Unless you have STIFF springs, I highly recommend using the top mounting perch position. Every thread I've read about using the lower perches has resulted in some sort of rubbing.

From what I've seen, the Koni Reds are true double-adjustables (like the Advanced Design shocks) .... in other words, you can adjust rebound and compression independently of each other (unlike most coilovers where they adjust both simultaneously). Now, I may be seeing Reds re-valved by Pro-parts (or whomever), so don't take my words as the absolute truth. And then you'll still have the issue with the mounting perches.

If you're concerned about ride height adjustability, you'll want to go with a coilover kit (GC, M2, etc.) along with the shock, or complete coilover system (Tein, JIC, Zeal, A'pexi, HKS .....). If you're just concerned with softening/stiffening the suspension, the Koni's will do just fine. But, as far as wheel hop is concerned, I don't know that the Koni's are going to solve that problem. I still have wheel hop with the Yellows turned down to 1/4 turn from full soft on the rears. But, the wheel hop could be a function of my 105,000 mile, old-*** trailing arms and toe links. Hope this clears things up for you.

Thanks you very much, thats the info I was looking for

The Koni yellows can be height adjustable without removing the shock. If you jack the car up and get creative you can do it, trust me. If you use the lower Koni perch settings make sure you change to longer bump stops. I did not and rubbed holes in the top of my fender liners after a few laps at TWS.

SPOautos

So from what I understand is the yellows on teh middle perch setting are basically like stock shock height, then you can move it one setting up or one setting down.

How do they compare to the Tokicos in terms of ride height? Is the middle perch setting pretty much the same as stock AND Tokicos are do you need to run the lowest setting to be similar to the Tokicos?

How does all this affect the bump stops with these aftermarket shocks. Do you pretty much have to change them with any of the shocks or what???

DOES ANYONE HAVE ANY PICS OF THIER SET UP WITH STOCK WHEELS???
