I have the same setup as you Ryan. It doesn't particularily bother me. I don't think I bottom out a lot, but I might and just not know.

I do not track my car or anything though.

well i thought the bilstein/Eibach an ok setup too.. but i've been out in other bmw's and they feel much more solid over bumps.. I switched the kit over to my "winter" e30 and wow do i ever feel it now! if i speed over any dip in the road and it sounds and feels like the shock towers are gonna rip out. It's a low - show setup.. and i don't want that anymore

thats why i'm askin ya'll

Im here, not in "off topic" I never am.

I haven't really tried many different suspension setups to tell the diff, I have driven Jay's car, and they feel pretty similar, althou i do see what he's talkin about compression and rebound, he's car rebounds good on the highway, and he's compression is slightly less harsh than mine.

But at 160+km/h, I think he's is slightly more floaty, if thats the word...donno how to explain it.

^^^^ Good man!

thats the thing.. the bilstein don't really seem to soak up anything when you hit bumps.. they just blast out the bushings.. but my gut feeling keeps telling me to get more bilstein's.

Floaty.. that's strange but it kinda makes sense.. either way at that speed you want something that will move easly and quickly to keep contact with the road..

Hey Ryan;

Most of my experience in Bilstien vs. Koni Yellows is from VeeDubs, both mine and others, so take this FWIW.

The Bilstiens are excellent and give great control and good ride quality with properly matched springs, like H&R Sports or Eibach's.
As mystical said though, their damping is insufficient with a "race" spring, and have insufficient travel with super short springs. This leads to bottoming out and greatly shortened life.
The Koni Yellows, with their compression adjustment, will work with a wider range of spring rates, and ultimately a stiffer/shorter spring than the Bilsteins. The adjustment is great in practical terms too, as you can set them softer for a reasonable street ride, and jam 'em full stiff for the track/autoX.
I've tried a few suspension set-ups in my Mk 2 GTI VR6 swap. I started with H&R sports and Spax adjustables, but the sports were way too soft for the track, and not dumped enough for the street. I then went to H&R race springs for a MK 3 VR6. Much improved set-up, but the Spax struts didn't have quite enough damping for the track, even on full stiff, plus I blew out a front strut a month or so after doing the race springs. I couldn't get warranty on the Spax (another whole story, but I digress) so I tried a used (but good) set of MK 3 Bilstein sports that a buddy had. The handling was even better, but the ride was absolute shit. Every little bump I hit my CD player would skip, and it bottomed out waaay too easily. (Remember, a Mk 2 VeeDub has a lot less suspension travel than an e30)
I finally bit the bullet and dropped a G note plus on a set of Koni Yellows. On full stiff, the handling was better than the 'steins on the track, and at about 1/3 gave a reasonable (if slightly underdamped) ride on the street. I could listen to CD's again!
The Koni's have now been on there for 4 years, 60,000K, and tons of abuse on both track and street. They're still fine. I may eventually go to a coil-over set-up, but only if the GTI becomes a dedicated track car.
So....my vote is for the Koni Yellows. The 'steins are great if your springs are not too low and/or stiff. There's not much diff in price anyway, and the adjustability of the yellows is a major plus, so why not.

Oh. and in case you were thinking of Koni reds, fuggedaboutit! They're not in the same class as either yellows or 'steins.

K, I've been typing enough, it's time for bed.

I don't see why everyone likes coilovers.. isn't bmw known around the world for building great handling cars or is that just BS. why would anyone wanna change the design that dramatically.
Because 90% of people who buy coilovers don't understand the true purpose of them, other than to "dump" the car which is actually improper use of the coilovers and a total waste of money if you ask me. You might as well just cut your springs to dump your ride. Linear springs are retarded for street driving and actually for bumpy uneven surfaces, it handles worse than any progressive spring setup I've tested. The H&R Sport gives you the best performance and are more than forgiveable for street driving. A perfect balance.

BTW, people this may shock you, coilovers are designed for balancing uneven weight distribution and tuning your car properly for weight balance, not to slam your rides for looks (you ricers!) LOL. If you want to slam your ride for looks, just get some coilover sleeves, or cut your springs

I've never had problems with Bilsteins bottoming out. Only that as Mystikal mentioned with stiffer race springs they do bottom out. The H&R race springs I find are actually too soft in the front for such a short spring (poor design), therefore I find the bilsteins cannot handle them in the front. I know a lot of people who have had problems with H&R race and Bilsteins on E36's. If you're going with H&R sport, I say get Bilsteins, H&R race, get konis.

FYI KONI's have 3 yr warranty whereas Bilstein has lifetime. Something you want to think about if KONI's tend to blow more often. You'll be spending more money on shocks in the long run.

I have only been in one other BMW and it had A'pex springs. I liked my ride more but that car probably had some other issues. Only other lowered rides I have been in have been mini trucks, muscle cars, and civics. So maybe I just don't know the differance. I plan on building a mini truck after the e30 so its probably best I stay ignorant.

It never feels like my shock towers are gonna rip out though, I drive my setup pretty hard at thimes the only thing thats jaring are pot holes.

IMO the eibach setup isnt even all that low..

Ryan,

Why would you want to run a 1.25" spring? Here is my car (below) when I had 2.5" springs and I never bottomed out. As for the Eibach/Bilstien setup.......they are fine since you don't plan on driving this thing like a mad man.

But i'm curious how Koni struts in the front and Bilstien shocks in the rear would hold up?

Eibach's sag like a MF. I had 2.1 degrees of camber in the rear when I first got the springs. Only 1 year later that rear camber turned into 2.9 degrees! My rear end was at least 1" lower than before. Not only do the springs sag ridiculous rates, they sag unevenly. One side of my front springs were lower than the other. What garbage US made springs they are, the paint even chipped off and the springs started rusting after 6 months, it didn't even seem like they were powder coated. Get H&R, they are made in Germany and good quality. The paint is amazing and doesn't seem to chip at all. I've had them for more than a year now and my camber is very consistent, no sagging at all and a much stiffer spring rate. The Eibach springs had very soft wonky handling. After installing the H&R's, it was like I was going from a stock spring rate to something much stiffer. I've been told that the Eibachs are actually using stock spring rates, the springs are just shorter and obviously making it more progressive.

Eibach may have been good years and years ago before they began mass production in American and were still made in Germany. However, those days are long gone. Get the H&R's.

Sorry this is OT

Julian I would stay away from FK, I have heard only bad things about them other than price point. Perches seizing etc. I would go Bilstein or H&R.
My 2cents.

Ok, my 2 cents. I don't what what is wrong with linear springs, I use them on the front my car. No issues at all. I'm hoping to swap for linear front and rear.

The reason why race springs bottom out easier is because they're generally shorter, and already closer to the bottom out bumper.

Coilovers are to used to corner weight your car, but they are used to fine tune the ride height also, which is very handy when you're running larger wheels.

Also, camber changes aren't only from sagging springs, they're also from wearing bushings, and slipping adjusters, it happens.

I currently run Bilstein PSS coilover setup, which are basically Bilstein sports matched to 400 and 430lbs/in springs. I think they're great for the street, not much of an option for e30's though, I don't think they're available.

Also, coilover sleeves on a bilstein sport shock with 400lbs springs practically the same as a PSS setup. I just personally wouldn't use sleeves for the track.

Adjustable spring perches do seize on Bilsteins and H&R, hell, they can seize on any model. Most adjustable perches are aluminium, they can nice and correded if not cleaned, especially from winter use. Aluminium on steel sure be coated with some sort of anti-seize compound, or at the minimum some grease.

FWIW, I am planning to swap over to a Koni (GC) setup, but only because they can offer more wheel clearance (on the e36 chassis anyway), and have a lot more choices when it comes to springs.

Sorry to bring the thread from the dead, but i was wondering the same thing

i have front konis, but i'd like to put bilstein ones on the back, since i wont really be able to adjust the rears easily (without disassembling the suspension)

Thanks
Alex

Why would you need to take the suspension apart? Make sure you get the proper koni adjustables which turn at the top rather than needing to turn the shock body. I wouldn't recommend mixing and matching dampers, just like I wouldn't mix springs. Different dampening, different design. Bilstein is generally stiffer than KONI's, even with KONI's stiffest setting.

I just recently switched from the H&R Cupkit to GC (375lb F) (450lb R) /Koni SA.

The Ground Control/Koni setup rides SO MUCH nicer then the Cupkit ever dreamed of. It handles bumps and road imperfections much better traction wise, and also harshness wise.

On the GC/Koni setup I'm also about 1/2in lower all around then I was on the Cupkit.
