Bilstein Sport with Coilover question

[Stephen]

Your shocks may be blown. Bilsteins run with H&R Race springs at 570 in the rear. Or are you so low you are hitting the bump stops perhaps?

I think theyre blown. 500isnt too stiff, and im running the 6inn springs that used to be yours. so, low but not slammed. Hopefully billy will replace them

[Stephen]

Well this thread proves it for me. My rear end bounces with 500# springs, and my shock mounts are fine, as well as poly sub frame and TA bushings. I guess i need to give bilstein a call.

[Wh33lhop]

Nope.

I have no intentions of revalving mine--when I want a real spring rate, I will get real suspension.

[robmespeedy]

From what I remember, Bilsteins are intrinsically simple and tend to cost less than the price of a shock for a revalve.

And yes, that is cheap.

any suggestions where i can get them done "cheap"?

[Wh33lhop]

i have 800/1000, i know my billies need to be revalved.
anybody know how much it cost to revalve them?

I'd suggest something like 500/750

We shall see. Jay spec'd 550/750 for my swap car with 22/19 UUC bars.

[Jean]

I had 500/650 with my bilstein sports, probably can't go much higher than that though. Maybe think about using Koni inserts instead?

[Bishop]

I agree... My 400/700 is fine for daily driving. Can be a tad harsh depending on the road conditions, but I would want higher spring rates if I knew the surface was going to be more optimal.

Now, correct me if I'm wrong, because this is just a guess, but if you go too high with your rates would this hurt you by causing the car to be a tad unpredictable? I was thinking high rates on a track may be good because it's usually smooth, fluid movements. But with autocross, the higher rates may upset the car with quick, jerky direction changes

Woops, edited because you edited.

Yeah, I realized I should put my number so the guy can actually call.

call me and I'll explain.

But here is the short, but still complicated version.

there are two worlds. the perfect world and the real world.

The perfect world is where you choose a spring to match a shock, or vice versa and it works because they match.

But in the real world, the damping and the rate may "match", but there are other things that are working against you.

On an e30 with Bilsteins, you have the spectre of bottoming always hanging around. It wont go away. You have to minimize it.

In order to make the car go faster, you have to do have two wrongs make a right. If you go too high on the springs, the struts won't dampen correctly, HOWEVER, the car won't be bottoming out which would be worse.

So an e30 with the wrong springs will be FASTER than a car with the right springs.

There is an analogy regarding wimmens in here somewhere, but I will leave that to someone else.
