can I downsize caliper

can I down size my caliper without changing the size of the rotor? My problem is I have 15" cragars and the calipers are really close, like a carboards width from the rim itself, so i was thinking if I could just get smaller calipers? Thanks This is on a Ford 9"

As long as it clears by that much, it will never contact the rim. As long as you have clearance you are good to go. 1/16" would be plenty. If the wheel or caliper bracket flexes more than that you have a bigger problem.

You probably won't find any smaller caliper for the current caliper bracket you are using. If you want smaller calipers it will likely require different mounting brackets also. Lots of smaller stuff out there if you are willing to change mounting brackets also. Try Speedway Motors, Wilwood, Strange, Baer, to name just a few.

Like Eric said, a 1/16" is plenty. However, swapping to the Wilwood calipers will gain you a little space and give you more braking performance.

Man that is a relief, I can see daylight between the caliper and rim , but its always good to have another opinion, brakes are something you don't wanna fool with I guess i have to tell the ol'lady she was right AGAIN

Often the tightest clearance is some casting flash sticking up on the caliper. If you take a file and/or some sand paper and knock off the flash it will give you a bit more room if you find you need it.

Only if you have the Wilwoods with Explorer type e-brake. The older Wilwoods with the Airheart type e-brake will move +/- .062 or so on the bracket and will contact some wheels - a $900 awww cr@p that I made with my $$$$ aluminum wheels. This is how close these are with the replacement 17" wheels:
