Q4TRO

Gents,

I sent my Bilstein Sports to the factory to have them custom revalved.
I contacted Hap before and ask his point of view on the setting increase.
I am running ABT springs.

Hap adviced to me the following:
+ 20% compression and +30% Rebound

I asked Bilstein to give me their opinion based on my ABT spring rates (front 415-425#'s and the rears between 440-460#'s)

Bilstein engineer just called me back with the following setting:

- Front: +30% compression +100% rebound
- Rear: +20% compression +25% rebound

I told Bilstein this was not my DD and I intended to use it on the track as well as on street.

I am a bit shocked by the 100% rebound on the front.
I really want the car to handle the best bust I do not want to mess up other mechanical/suspension parts because of the crazy rebound.

What do you guys think of it?

IF the rebound rate was small then increasing it 100% may not be a big deal. Question to ask is why so much..

Linc's S4

a different base line, then his might only need 25%.

Q4TRO

100% increase over standard Bilstein Sports

Q4TRO

Bilstein engineers said so much because of the car's heavy nose

Q4TRO

Sorry did not mention: Hap had the exact same shocks as mine: Bilstein Sport

Sloooo4esT

so would these reduce nose dive while braking?

Q4TRO

Considerably!

Not to my knowledge. compression can but rebound?

Q4TRO

You're right, I thought he talked about the compression increase
