I need to space the rotor on my 87 IROC out by about 1/16" in order to properly center the rotor in the caliper bracket. There is no way to reposition the bracket inboard without re-machining the mounting point on the axle (which isn't something I have the sources to accomplish locally). I have looked at 1/16" wheel spacers. The problem with this is that the spacer HAS to fit up inside the rotor hat. I saw some "stock car" spacers on a site that I thought might work, but they are 5x5 instead of 5x4-3/4. Suggestions???
I had to do the same thing on the rear of my car. I found a shop with a laser cutter measured the OD, ID, thickness and bolt pattern and had shims laser cut. He cut me about 8 shims so I would have spares for $30. Good Luck.
Anybody know of a place that'll do this by mail? I really need to get this done soon.
Thanks for the info - wish I had someplace local that did that! Hopefully someone will chime in. Surely one of the shops on here either has a laser cutting machine or knows someplace that does?
Couldnt you use a drill press and a circle cutter and make your own 1/16 is pretty thin. Or use some Abs plastic to make a template and send it off to any machine shop.
I thought about the washer idea and figured it wouldn't be safe. I don't have access to a drill press unfortunately and yes, it is a floating caliper setup. It's the 89-97 OE Camaro brakes. I added them to my car several years ago from a 93 or 94 Camaro.
It's the caliper mounting bracket that needs to be centered over the rotor. The rotor is right up next to the back side of the bracket, so it needs to be pushed outward slightly. I'd love to see about 1/8" clearance on both the front and back sides of the caliper bracket between it and the rotor.
