I know I want 18". Most probably will be rota GTR's.

 

My car is is lowered 30mm, what is the absolute widest the rears can be without catching, I don't mind having a bit of stretch on the tyres either.

 

Also, as for the fronts, what is a sensible width? 8j? What offset should the front have?

 

Thanks, Dan

there was a member on here that was selling a set m8 check in the search box for rota's.

All depends on offset dude. I'd say you can probably get a 10" wide rear running a +35. Much wider and you risk it rubbing parts of the suspension. You could go wider if you fitted an NA subframe and ditched ALL the HICAS stuff. As for the fronts, if you fit 10" rears, go for 9"....with maybe a +25 offset.

I agree with Simon, although If you're set on the rota gtr's then you're limited to what you can get, here are your options (offset recommendations are based on those available for the rota gtr on driftworks shop):

 

Option 1: The classic 8.5" front and 9.5" rear combo. For this I would recommend 18X8.5 ET25 225/40-18 front and 18X9.5 ET30 (to match the fronts, ET25 would be ideal but then I'd space the fronts to ET20) 255/35-18 rear.

 

Option 2: 9.5" all round. This would be the best looking option IMO as it will give the front wheels a nicer look with the concave design. My recommendation, 18x9.5 ET35 245/40-18 front and 18x9.5 ET25 255/35-18 rear.

 

Option 3: This is the only way to get a 10" rear with this design of wheel although it involves using rota gtr-d wheels which have the same spoke design but have a large dish. I'm not 100% sure what design the spoke face is like on these, with regards flat or concave. If it was a flat design I'm not sure that putting the 9.5" fronts with the concave would match? So you'd have to go for the 8.5" flat face (same as option 1) with 18X10 ET35 275/35-18.

 

I'm not the biggest fan of the gtr-d although I have never seen them in person, but my current stance on those options would be option 2, 9.5" all round. Note that ET25 or less on the rears would require an arch lip roll - £90 from arch enemy. All cars seem to vary in clearance with the same offsets and also bare in mind that other settings such as camber will also affect arch clearance.
