Greetings All,

In the process of fitting some aftermarket 15” SSI wheels onto a 1972 Cutlass. The wheels are brand new 15” x 8” with zero offset. The car has Wilwood six piston front brakes with the 12.19” rotors, and herein lies the rub.

When putting the wheel on the car it is about a quarter of an inch from the wheel mounting surface when the caliper hits the rim. It’s not an almost-made-it kind of interference, but a Full Stop. Would really like these wheels on this car. American Racing makes the Outlaw wheel in 15” and these fit over the caliper just fine. Have considered a small spacer or grinding the caliper down a little bit, but grinding a caliper scares me a little. Somebody designed them that way for a reason, so I leave them alone.

Has anyone else worked with putting 15” wheels over the 6 piston Wilwood calipers? These are the calipers from the 12.19” rotor A-Body kit. Suggestions or ideas? I would appreciate any thoughts anyone might have.

Thanks,

David

 

Those wheels are designed to clear the stock 10.75" rotors. I doubt there are any stock-style 15" wheels that will clear your 12.19" rotors and calipers. Start saving up for the 17" billet versions.
