5kCSTQ Performance Modifications

Bill-
Two big problems with your suspension setup:
First, your shocks are not valved properly for your springs
Second, your wheel/tire combination is not well suited to
the rest of your suspension

This will result in poor ride, as you've noticed, as well
as sub-par handling as all of the suspension components are
not working in harmony.

I would recommend getting properly valved shocks for your spring
rates and going to a stiffer sidewall.

My 5ktq has a 3 inch exhaust from the downpipe back, including a 3 inch
cat.  I Got away with no flat spots or crimps anywhere by
removing/modifying that drive shaft brace/subframe piece just behind the
cat.  The car has a chambered "warlock" muffler that is a flowmaster
copy.  Overall the exhaust made a huge difference, and I would recommend
going with a 3 inch over 2.5 inch exhaust.  I had mine bent at a local
INDEPENDENT muffler shop for about $200 from the dp back including the
muffler.

I have H&R 200 20V springs with Boge Progas in the front and Boge sport
in the rear.  As far as I can tell, this combination really shows how
stiff the unibody is not.  Progas shocks have a "load zone" that is
REALLY firm. The drop in the springs puts the car in the load zone all
the time.  The rear is a little underdamped.  Most of my suspension
travel is coming from my tires which are 60 series. This is not ideal,
ride is very rough.  But the car tries very hard to avoid pitching and
rolling at speed.  At the limit the car is very well behaved for its
size.
