I just did fitments on the new robispec 370z on the rear I can get a 12" wide wheel (with 315 tires) the offset would be around 25 (the shop car has 10.5" wheels with the effective offset of +13 this leaves no room on the outside but 2"+ clearance on the shock (not coilover spring as the car has a race spring conversion in the stock spring location). If you went to coilovers you would lose 1" of this available width due to the spring raped around the damper. on the front the 10.5" wheel fits fine with an offset of around +30-25. The robispec Z will end up with a "square" setup of 10.5 +38's all around running 285/30/18 tires. with ZERO clearance issues..imo the only thing limiting the tire width up to 315's is the rim...as always ymmv..
