ET38.

Standard beam and if the wheel went straight up it still wouldnt touch the outer arch. The only part its ever rubbed on is the inner arch when 3 up and with the boot full.

Mine only on Konis and Ahmed track specs, i guess yours will run coilovers so wont squat that much. The picture above is on boost in 4th.

I also ran the same size tyres on a 7.5 rim and they were fine. Tbh if i could i would go for 7.5 front and 8 rear.
