Well I have all 4 Koni yellows off the car for the install of my GC kit. The rears are still stock valving and compression seems to be pretty equal.

The fronts I had Truechoice rebuild/revalve over the winter. They have 1 double regional, a 1 hour enduro and 5 autocross runs on them since rebuild. On one of them I am able to push the rod into the strut and it rebounds. The other I can barely get it to compress. Both of them are set to full soft while doing this. The units were revalved with 380/lbs being the minimum spring rate.

So the question is is the one I can compress blown out again after very little track time or is the stiffer one having some other kind of issues.

FYI the one that is easy to compress was on the RF which was only loaded on 2 turns roughly at Beaverun. The stiffer one would have seen the majority of the load.
