[Biturbos4] Quick question about springs and shocks

[Wilson Northrup]

Lowered springs for the S4 will have increased rates over the stock S4 
springs as there is less travel.  This is common for any car.

The only exception that I could think of for this is if someone cut the 
stock spring.  DO NOT CUT YOUR SPRINGS.

Unless the koni's are modified to be short stroke, or shortened barrel, or 
if they are some type of generic race shock which has been tretrofitted to 
use on your vehicle,  they they will have a stroke compatable with the 
stock spring.  The standard "Koni Yellow" as it is often referred is an 
oil based street shock which is designed to be compatable with stock 
springs.  By compatable, I mean that the vendor claims that it is designed 
to improve the handling of the vehicle when used with stock springs.

Any comments about ride quality suffering should only be directed to those 
who prefer a soft ride to increased cornering performance.   Ride quality 
is very subjective and opinions of ride quality are not common for all 
drivers.

'00 S4 Biturbo  - stiff ride for some, nice ride quality for me.
'00 RX7 TwinTurbo - harsh ride for some , nice ride quality for me.
