If you are using 1978-88 GM Metric style brake calipers your choices of piston sizes are pretty much limited to 2-1/2". This isn't bad unless you want to 'tune' your braking by using different size calipers front to rear. By using a larger 2-3/4" piston you will increase the braking force at a wheel over a wheel using a smaller piston. Bleeder and inlet are both 10mm-1.5 inlet allowing the caliper to be used on either side. Plus, these calipers have been ground smooth to make them easier to paint. Includes pads and hardware. Sold as ...
These are based on the popular GM Metric calipers with 5-1/2" mounting centers. Undersized: 6.620 lbs.10mm - 1.5 inletUndersized Metric Calipers:Can be used on the right front of open wheel modifieds and street stocks on dirt surfaces to reduce right front braking bias to aid in corner entry. Can be used on the rear of open wheel modifieds and street stocks racing on pavement to reduce rear brake bias.

These all new cast, not rebuilt iron calipers are bolt-on replacements for 1978 and later GM Metric calipers widely used in "spec" racing categories and low cost disc brake conversions. Not IMCA pproved. Wilwood iron GM Metric calipers combine new part quality with modern machining precision. There are two piston size options to assist builders with properly building static bias into a car. Previously, builders using the metric calipers generally had to mount the same size calipers on all four wheels. This drastically limited the tuning options and often created ...
