I currently have 15X8 zero offset rims at all four corners on my Cosworth clone, running 225/50-15 tires. My front springs have at least a half a coil cut off. At full steering lock I have some minor rubbing against the plastic inner liner and on large dips in the road I can hear some occasional rubbing but cannot find what is hitting, no marks on tire or fender well. Your coupe may also have larger well openings than my Vega and using a lower profile tire, your 225/45-15, may have more clearance although I don't know how much wider your tire may be. My front sway bar, 1.25, is larger than the Spyder's V8 bar which I believe is 1.125. My shocks are KYB Gas-Adjust. My wheels have a 4X100 bolt circle, here's a thread with some explanation, I'm the third post down,
