H&R and Bilstein will be firm. I have H&R Sports Springs and Koni FSD and its a perfect setup for those with kids who need excellent handling but a super smooth ride. The price of FSD is nearly the same price as other Koni's or Bilstien.

I have relatives that live in your city and have visited many times, but not for many years.

I just got Bilstein PSS9 doubly adjustable coilover suspension..it is adjustable..so if you have your grandmother in the car...you can make it more comfortable...and change it to more aggressive for when you take it to Spa.

I would go for Bilstein, as a company they produce some top notch stuff, if I could only afford them though...KW is very good as well though. I may settle for these (only because of price, go for Bilstein if price is not an issue)

Both are great setups but I too would recommend the Bilsteins over the KWs. Bilstein shocks are known for their longevity and performance as great OEM upgrades. That's not to say KW is of lesser quality, but between the two I'd go with the Bilsteins. Not to mention, lifetime warranty on the shocks is pretty slick

I know that bilstein is better also more expensively from KW, but the subject is that it is very hardly in the street, and because I have children I am afraid that him craze's in the shake , and because rather I lead to the market KW you what is recommended in my own case? I'm sorry for English!!!!

Nick, are the Bilsteins' range of travel designed to go with the lower springs (e.g., H&R Sport or Race Springs) vs the OEM ones?

KW has a smoother ride. The springs or something is done differently not to give as harse a ride but the performance is amazing.

KW offers LIFETIME warranty as well and is shiny stainless steel

Bilstein is good stuff but prefer KW. More friends run KW now.

I saw a KW suspension on a car and the rings that you turn to adjust the height of the car and that the spring sits on is made out of PLASTIC!!! The Bilstein is made out of metal. That should tell you something. I wouldnt want to be in the car when that piece of plastic breaks and the spring and the shock collapse. But hey thats just my .02

The plastic is more than strong enough in compression and it is reinforced. The reason they use plastic is to reduce noise. BTW, you do know the top of the struts are held in by molded rubber only.

Yes I am 99% sure the Bilsteins are designed to work with both OEM and aftermarket springs.

Point being, its still a piece of plastic. My PSS9's dont make any noise whatsoever. I just wouldnt want a piece of plastic holding my compressed spring.
