So..just to let everyone know I have done a number of searches and research and, as certain as I am, after all that I still would like to double check with the group and get a second opinion. Especially given the price these rims and tires. Car is a 2011 IPL.

The Specs:
TE37 Saga S-plus
Fronts
19" x 9.5" +35 with 265/40R19
19" x 9.5" +22 Alternate Spec
Rears
19"x10.5" +30 with 295/35R19
19" x 10.5" +22 Alternate Spec

Based on the Rays website the +35 and +22 fronts clear the CKV36 skyline brakes but the +30 rears I've speced do not (the +22s do)... however the +30 rears apparently clear the R35 GTR rear brakes... is this maybe a typo?
My goal is to avoid having to camber out at all and try and maintain a flush look with as much tire on the ground as possible, hence the +35 and +30 specs. The car is twin turbo and over 600whp, so more rubber on the ground the better. Any feed back is appreciated!

 

I'd go with alt spec for both front and rear. In fact I just ordered a set of fronts in your alt spec of 19x9.5et22. My 10.5 rears would have been +22 if my suspension was stock, but I have an extra 10mm to fill, so I went +12 on my coupe.

 

I'm lowered on KWs but I'm trying to avoid stretched tires and negative camber. Ideally I'd like to go with the 295 on the rear (best case) or 285 (worst). The +30 just seemed to make more sense to achieve this.. what tire size you going with? +12 is pretty aggressive.
