bebby Posted January 28, 2015 Share Posted January 28, 2015 Right guys and girls I require some info from the Fitment gurus amongst you I'm going to invest in some Rota grids for my supra and I'm not 100% sure on what offset to use bearing in mind it's still on standard suspension and arches are not rolled The options I have are as follows 18" with 8.5 front and 10 for the rear With ET20 front. ET35 rear, ET30 front ET35 rear, ET35 all round And so on all the way up to ET44 The offset always baffles me and any help would be much appreciated as looking to have them fitted for the new season cheers Quote Link to comment Share on other sites More sharing options...
masterfett Posted January 28, 2015 Share Posted January 28, 2015 not much help but the et20 wont fit under stock arches. I had ROTA GTR's on my old supra and they where et35 all round, a little to flush fitting as needed a little tyre stretch to stop them scrubbing the arches.

Rob W Posted January 28, 2015 Share Posted January 28, 2015 My winter wheels are 8.5 x18 et25 and sit flush with the arch, lowered and 235/40 tyres with no rubbing. You might get away with et20 but that's not for sure. Otherwise just got for et30 on the front, the rear you would get away with et35 with an arch roll or cut.

Nic Posted January 28, 2015 Share Posted January 28, 2015 (edited) If you have the larger 4pot/2pot Supra brakes you will need to make sure they clear the calipers. Assuming they do 18x8.5 +30 & 18x10 +35 would be what I'd go with, they will sit just about flush with the wheel arches, you *may* need to roll the arches slightly but will depend on how much the car is lowered and size and make of tyres you use.

Cheers they're clearing standard j spec brakes so shouldn't a be a drama .. Thinking of going with whifbitz for 9.5 fronts and 10 rear ET35 all round and if needs be to get 265-275 tyres I'll get them to roll the arches ...
