BBS Fi-r 20s offset?

I want to be able to fit Toyo R888 315s on my rear so I'm not entirely sure the best size and offset. Looking for expert opinion on correct size for 20s on front and rear. Minimum width of 10.5. Thanks for any help.

I was thinking 20x9.5 +22 / 20x10.5 +35. Only 11inch rear wheel that might be to aggressive for 315s. ��

Fi's are 26F 28R, F1-R's at 25 on a 10.5 will be 15mm further out than stock, it will be very much down to bulge I am running 15mm spacers soit will be down to a 315 profile on the 10.5 rim, I think you will need a less aggressive offset at the rear

You really need to see what the tyre bulge is on a 10.5 " rim, if you fit et 35 (your first post suggested et 25) which is the offset of the 10.5" rim the rim will be 7mm further in at the rear and 5mm further out than stock. add the bulge on the 315 and I am pretty sure it would fit, but might look a little too inset at the rear.

With a 10mm spacer on the F1R (et25) you may find the bulge on the 315 a little too much, I think it would be snug but good.

Have a look and you will see what I mean. This is just a guide, I am running a 15mm spacer at the rear so et 34-15= 19. this is with stock wheels and tyres

Tires Front 265 PSS Rear R888 315. I was thinking with bulge I was going to be almost perfectly flushed on rear. Right now I run the 315's with no spacer on the rear and there is maybe 5mm more room. Worst case I might need fender rolled but hope not. R888 I have to do. 800rwhp problems lol

If your running stock with maybe 5mm gap then it makes sense, in any case you can always pop on a spacer and it's not as if you can order a different offset (Other than the F1's)

Unless of course you go for something like the BC forged RZ05's a wheel I am quite interested in
