D154-R Single Piston Floater Description

Wilwood's newest race caliper, the D154-R starts with a forged aluminum Type III hard anodized body with stainless steel piston. With a choice of 2.50” or 2.00” pistons and covering rotors from .81” to 1.04” thickness up to 12.19” diameter. Caliper fluid inlet port centered directly behind the piston eliminates any interference with slide pins. Lower deflection rate and higher volumetric efficiency than all the competitions’ heavier cast models, D154-R calipers with a 2.50" piston weighs only 3.3 pounds and use standard metric D154 pads. Caliper mounting uses stock height and offset.

GM-Metric-Iron Single Piston Floater Description

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), request part no. 230-0619 (slide pin kit) that contains 4 slide pins, enough for two calipers.
