BSK is for the rear, and it's mainly to "fix" the dynamic toe changes that the AP1 has when you load and unload the suspension while cornering.

As for offsets. +60 is your best bet for no rubbing both on fenders or your A-arms while at full lock.

Keep in mind that under massive compression, you might still rub your fenders a bit.

I know some guys at the track will rub their front fender-liner on stock rims running 225/255 at one of our local tracks, but it's because of the massive compression that occurs in the banking of that turn at ~115-120mph (bone stock S2K - running stock class for our competition series).

 

Haha, yeah it was getting late =)

 

I am also considering getting a set of PF01SS. Take pictures and post here. Especially if white.

Also, suppose i will add to the thread.

I am on OZ Aleggerita 17x8.5 +58 X4, on 245 Star Specs. Lowered, nearly 2 degrees of camber. I rubbed ever so slightly on the inner fender liners. Not enough to wear through the plastic, but just to make some 1/2 millimeter scuffs in 2 spots.

Got a stiffer FSB, but the insane increase in front grip has caused a few oversteer crashes. Rear bar removed for now, will be trying new things over the summer.

I was hoping to find a wheel available in 8.5 and 9inch to stagger 245/255, but none exists.
in 17x9 it looks like its either PF01, RPF1, TSW nurburgring, Tire Rack's brand, or wait for the new 949 wheels in the fall.

Currently leaning towards Tire racks brand and repainting gold or bronze due to large price difference over the enkeis.
