I used to have Apexi coilovers on my STi which I replaced because of the horrible shape
they were in. I opted to go with Tokico D-spec 6-way adjustable gas shocks and RCE
(Yellow) lowering springs. Personally, I feel that the ride quality is far more comfortable
and the performance is very comparable to my previous coilovers. These shocks are much
easier to tune (the damping rebound) than the coilovers ever were. I can adjust all 4
shocks in 10 minutes or less. I like how that allows me to adjust the attitude of the car,
especially since I am wingless and the rear end feels lighter at speed, which I try to tune out.
I have the RCE Yellows, like I mentioned, but I have always wondered what the RCE Blacks
"Regular Guy" springs feel like (they are a bit softer than the Yellows "Street/Track"). I imagine
that if you don't plan to track the car, or only rarely compete in Auto-X, the Blacks might be
nice for you.
I know you were thinking coilovers, as I was for a long time, but I hope this helps you out in
making a decision.
