Can someone tell me if Pontiac GTA or Buick GNX wheels will fit an 85 MCSS with a stock suspension without any clearance issues? Is there an aftermarket wheel that looks like either of these wheels that works? I'm currently running 15X8 Rallye wheels with 4" backspace. Not sure of the offset. Tires are BFG 255/60R15 tires with no issues in the back but a slight rub in the front when the wheels are turned all the way.
