APEX ARC-8 wheel fitment

Just some more info, and will post pics after car gets cleaned this weekend.
Have tried numerous sets of wheels (Stock, OZ Alleggrita's, Advans), and now APEX ARC-8s.
These are amazing wheels, and look great.
We have the 18x8.5" on the front, and 18x9.5" on the rear. The set we have on the car right now will be our street fitment, and we have another set that will be our track setup.
But, wanted to run a conservative setup at first.
On the front we have 245/35/18, and we have Vorshlag camber plates (the best), and also the M3 lower control arms. After installing the wheels, we put the car on our alignment rack to play w suspension settings to see what we needed to get the proper clearance. NO question at full negative camber, you have tons of clearance on the front w the outer fender lip. We went as low as -1.6 degrees of camber, and would rub on bumps. At -1.7 degrees, we would rub at full lock and on bumps. At -1.8 degrees, we had clearance with no problems, and have been driving this way since, and have not had any issues.
On the rear, we used to have to run insane amounts of negative camber to get the fender clearance, but w the new wheels, we have HUGE amounts of clearance. We have 255/35/18 right now, but have HUGE amounts of clearance at the outer fender lip, and this is with only - 1.5 degrees of camber on the rear (we used to run - 3+ on the rear to fit).
We then put the car on the alignment rack, and examined the clearance, and we have clearance on the inside fender well, shock, and all other elements, and could run 10mm spacers on the rear w the 255 tires without a problem.
We didn't want to run really large rear tires, as we are still working to get the perfect balance for track use (but, at the same time, we can still break the tires loose in 2nd and 3rd gear under hard street acceleration).
LOVE the wheels.
We have another customer who just bought a set from us in Satin Black....let us know if you need a set, as you can get them from us (BRracing)
