These are all new and not rebuilt, cast iron calipers, purpose built for racing. Wilwood’s GM Metric Calipers are bolt-on replacements for 1978 and later GM Metric calipers widely used in "spec" racing categories. Wilwood’s new 2.50” piston GM Metric calipers are now officially approved for IMCA as OEM replacement caliper that meet all rules in Modified, Stock Cars, Hobby Stocks, Northern and Sothern Sport Mods. The GM Metric caliper is also available in 2.75” and 2.00” piston sizes for use in other non-restricted series or applications. Calipers require use of hardened Wilwood slide pins (sold separately), Willwood part no. 230-0619 (slide pin kit) that contains 4 slide pins, enough for two calipers.
