I have a 99 C4 that i bought to be my daily/stress reliever/makes-me-feel-good car. However a E46 M3 for a long time, i do need help with some ideas on how to properly set my car up in the way it fits in my life.

Things I've done or already done to it:
New crate motor
IMS fixed
New radiators
New shock mounts
New water pumps
H&R Springs
Turbo suspension
997 shifter

The role that i want for it is a long range, GT type car that can make the NC/ATL/DC trip without worry. One big thing i do care about the most is ride quality, driving dynamics, and sound. I could care less about horsepower.

Any ideas on the best type of suspension setup?
Best exhaust?
Best long distance comfortable tires?

Any help would be very very much appreciated.

 

Any ideas on the best type of suspension setup? Bilstein HD Shocks/Struts with OEM springs

Best exhaust? Fabspeed

Best long distance comfortable tires? Michelin PS2

Added Bilstein PSS10 to my C4S and couldn't be happier. Great mod, can highly recommend!
