I want to buy some good street/occasional auto X rolling stock and don't want to break the bank but also don't want to compromise on fitment by opening up my options to less backspace. I am about to pull the trigger on the following: BG rodworks Old School wheels and Falken Azenis RT615K+ tires in these sizes. Front 17x8 4.75" BS with 245/45 Rear 17x9.5 5.5" BS with 275/40 The calculator I am using shows that both sizes have the same offset as the stock steel Z28 wheels so the extra size is split 50/50. Fronts are .2" closer to fender lip and same to the suspension side and the rears are .8" closer to fender lip and same toward the leaf. The car is lowered about an inch with Hotchkis springs and spacers/shackles. Front suspension geometry is stock other than tall upper ball joints which should only help with the more aggressive camber change. I tried to do my homework especially from the guys who drive their cars hard and this seems to be a pretty safe combination I believe. I plan to compare these numbers to the clearance around my 15" combo I have now but does anybody see anything wrong with this selection? The attached pic is an RS with the style wheel I am looking at.
