Why are Bilstein Sports so ROUGH!?

[Bearmw]

FWIW my lightweight (2800 lb.) cabrio has M3 rear springs and H&R sports up front. I was running KYB gas front and rear but found that the KYB's didn't have enough rebound dampening as the front end would bounce a bit too much with certain bumps. I replaced the fronts with Koni and have them now adjusted to about 1 1/2 turns stiffness. It feels much better and controlled than the KYBs. I am not sure about the Bilsteins but I like the Koni's in my application.

My car is a summer weekend car and the roads suck in many places I drive.

I made the Koni switch on my cabrio after I dont know how many cars w BS Sports and the difference is night and day. Zero loss of handling once they are dialed in and zero bone shaking over bumps.

Bye bye BS

I'm glad this thread got bumped. I was JUST about to pull the trigger on Bilstein B8's but now I'm having second thoughts. Obviously up here in Canada most of our roads are not glass smooth, but my E30 is only a summer / weekend fun car and not daily driven.

I looked on Tire Rack and they have Koni's on special now too. So I think now I am going to go Koni's with H&R super sports. Thoughts? My 318is is bone stock with the original OEM shocks and springs...well beyond blown to say the least.

I have billy sports and h&r super sports. Its a great ride not sure they are "rough" maybe im just to young and not used to the floaty ride you get from a Cadillac

If you're doing any street driving on less than glass smooth roads, YES.
I've had billie sports and koni sa. Still on konis.

Was looking to get H&R sport springs with koni adjustables or h&r touring cup kit. Both seem to lower the car the about the same amount. Car will be daily but you know occasionally spirited drive. Anyone have experience with either. Is the koni adjustbles worth the extra fiddling with adjustments?

I noticed a noise coming from the rear pass side last night and when I got under the car I found the black rubber bumpstop wedged between the top and bottom of the shock. Checked the left side and that one was MIA.

I'm gonna just run without them, but wondered if anyone else experienced this?

Bilstein street struts with lowering springs??

Dear Forum:

This year, I put new shocks/struts and sway bars in my '87 325is. I have used Eibach springs on an E21 and had fantastic results. But the air dam on my 325is hangs pretty low and is going to get hung up on curbs if I lower the car ( I just repainted it and want to keep it pretty).

Unfortunately, the car doesn't handle all that well with the stock springs. I didn't buy the sport Bilsteins, but the best street grade shocks/struts. Is there any reason why I shouldn't put lower springs on the street struts?

One last thing...Can I rant and complain?? I purchased ST sway bars for my car and want to rip on the people who make them. My rear sway bar wasn't properly shaped. The right end of the bar sits too close to the spring to use the half-assed end link system that they provide. I contacted ST for help and they couldn't have cared less. I had to fabricate my own end links, which was not that hard....but why should I have to?

I've been driving for awhile on the Konis now and it's definitely an improvement. Not harsh, but still firm.

As others said, manhole covers, cracks and raised bumps in the road are no longer making me clench up. I've got the frt set at 1/2 turn along with the rear. Strut bar does make it difficult to adjust front struts. Found it's just easier to remove it since once you're dialed in it's not an issue any longer. Unless your strut bar is different from mine of course.

Did a Z3 steering rack upgrade at the same time...should've done that a long time ago too.

Anyone else make the switch that can comment on the ride difference?

[TrentW]

Just saw the old thread on this and he had the same problem. Can someone confirm that it's not supposed to tighten all the way in?

[TrentW]

Can someone tell me wtf is going on?

I wanted to assemble struts today, but the gland nut won't fit with the inserts. Car is an "is" so I ordered the non-sport part # cause I knew the Bilstein style won't fit. Filled with 2 tbls ATF and slid in the Koni insert, put spacer on top of insert-but this happened. Do I need the other hex style gland nut?



Even with the spacer removed, the nut won't thread far enough in.

What's the frequency, Kenneth?!

Use the sport bump stops?

[nando]

Thanks Nando.

Pre-adjustment is for rears so that's done.

You guys running bumpstops? Thinking I may run without. Car is never driven in rain and stored winters, avoid potholes, so what's the point?

Run them up front. Ive never ran them in the rear, haven't had an issue and i ran them like that for almost 15 years.. Prretty sure i will have coil bind before they bottom out anyway.
