12j rims, what offset do i need?

[mikeekim89]

As above really.. looking at some 12j alloys for the back of my supra. But im unsure of the ideal offset. Fronts will be 8.5-10j so advice on those too would be nice. Ive got uk spec brakes and I'm looking at Rota GTR-D.

 

Would anyone know the ideal offsets for the fronts and more importantly the rears?

 

Cheers

Stock body or wide arch?

[ShawnPreece]

As Berg said we would need to know your arches if stock or wide...

 

If wide then im running a ridox widearch kit and I use 18x10et35 on the front and then I use 18x12et20 on the rear which sit perfect imo...

 

 

but need to know what your running

[ShawnPreece]

Just noticed you said UK brakes... im running UK brakes too and front wheels did touch the caliper just when tightened so an extra few mm out on the offset would be ideal to make things easier for fitting rather than modifying it

Im going ridox wide arch. Factory atm.

 

Looking at wode arch front too possibly. Been offered both +20 and 0 on the rears and +15 on the front.. but 9.5j would this work?

12 +20 on the rear would extend beyond the stock wheel arches by around 40mm.

 

9.5 +15 on the front would extend beyond the stock wheel arches by around 25mm.

I measured, im going wide body. 35mm rear and 25mmish front too the tip of the rims too edge when fitted. Im looki g at wide arch now. Could I get away with a 25mm each side extension do you reckon as its only just over or would I have too go ridox 40-50mm wide arch? Im ideally hoping to put oem wide arches in
