Adjusting Ground Control Coilovers
I'm guessing you lowered the perch ring on the Konis, didn't you?
I did it, too. You will most likely find that even with all the perches set at the same static height, the car's stance will not be the same at all corners. Readjusting is inevitable. For the rears(AND REARS ONLY!!!), I use a scissor jack between the tire and the upper fender wall to push the suspension down enough to easily rotate the perch.

My passenger side fender is messed up to prove it. I talked to a lot of other people who ran Konis and Espelirs and I seem to be the only one with this problem.
That's how I ended up getting the GC. It actually worked out for the better because now I have full adjustability of height and dampening, and I'm running a much stiffer spring rate in front when compared to the Espelirs which so far I like.

Shocks don't determine ride height.
I know Konis aren't supposed to affect ride height, but believe me, they did. PoLe_PosiTion can confirm, he was there for the install. And they can affect ride height if the distance between the top hat and the lower perch is shorter.
Yes, I understand the top hat doesn't move. I've had them off the car and back in 3 times now. Hence why I said the "DISTANCE BETWEEN" the top hat and the lower perch, meaning that the distance between those two points is shorter with a Koni shock when compared to an OEM shock with the same Espelir spring. So yes, the only place that this can be different on the Koni shock is the ring seat.
Another reason why I think other people have not had this problem is because of the tire size. My street tires are a 225/40-18 in front and that's where I was having rubbing problems. When I put my R-comps on for the last HPDE (205/50-17), I did not rub at all. In fact, I left them on for a couple of weeks after the event until I got the GCs in because I didn't rub. So I'm guessing, other members on the board who are running Espelirs and Konis are probably still running OEM wheels, but that's just speculation.
Regardless of why I had this problem, I have the GCs installed now so my problem is solved. What's done is done, even though it doesn't make sense, it really doesn't matter now. I wasn't asking if my Koni shocks were the problem or not, I was telling you. I was lower with the Espelir/Koni combo than I was with Espelir/OEM so I got the GCs and I'm all set now. I just have to get a body shop to fix my fender and luckily their was no paint chipping, it just bent it out a bit. My fender lining and my S-03s have a bunch of rub marks on them, but I can live with that.
BTW - Thanks for the tip on the rears

I thought you were saying that among the four Koni shocks the fronts were different than the rears.
