High-speed compression has little to do with spring rates. Its job is to stop the wheel that is going up after hitting a sharp bump at speed. It is mostly determined by your unsprung mass and wheel travel. If you have stiffer springs, you can even get away with a lower high-speed compression damping.

Yes, high speed compression is the bump response, but if it's not valved properly for a stiffer spring, then the car can potentially pogo from hitting a bump because the lower oscillation control may not be sufficient to damp the greater amount of energy that the spring has stored from the compression in the hit.

If the valving didn't matter, KW wouldn't be such a pain to deal with. KW has said that due to the fact that they've hardly sold ANY of their kits for the 3/S in the US, and have no opportunity to test the kit on the platform, they're reluctant to make a set with the spring rates I want and won't guarantee it if they do.

So what have you got in the works Phil?

I know a guy here in Germany that had KW variant 3 coilovers and had problems with it. Mostly there were clunking noises. He went to the KW factory to get it fixed because they do that for free as those things are covered by their warranty. 3 Weeks later the noises started again and he decided to get rid of the KW and buy K-Sports instead.

I've been thinking a lot about those KW because basically it's still the only suspension setup I can get road legal over here and they have an excellent reputation. But then I don't know what to think of the stuff this guy told me...

This thread is the first I've know that KW makes anything for our cars. Good to know for the future.

He also said the bodies corroded IIRC. He told me to not buy them when I was shopping coilovers. This was before the K-sports came out.

Last time i checked KW's were stainless

KW's are stainless and I never heard of anyone having Problems with corrosion.
On the other side I have hear disturbing stories of K-Sports rotting away even where they are anodized.
Seems the anodizing is pretty weak and wet and salt in the winter will pretty much ruin them.

So is the exhaust on my F-350 and the props on my boat. If you think stainless steel can't corrode, I have a bridge I need to sell for cheap.

I'll look for the pictures he sent me, they're on my old external HDD.

I'm aware stainless can corrode under some circumstances, but in comparison to other coil-overs I'll take stainless...

But enough hi-jacking of this thread... if you have those pics PM ME i really wouldn't mind taking a look...

Heh, this is the first time I am seeing that a suspension company would advertise how corrosion resistant their dampers are. It could be that they used to have some corrosion issues that cost them dearly and created a bad publicity, so now they must have fixed the problems and are trying to persuade that the issue does not exist (anymore). Okay.
