Wilwood's newest pure heavy-duty race caliper, the D52-R starts with a lightweight 2kg forged aluminum Type III hard anodized body with a stainless steel piston. Choose a width of 70mm or 60.5mm pistons, and rotor widths of 20.5mm, 26.4mm and 32.5mm thick in common 298mm, or 309.6mm, and up to 317.5mm diameters. 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, D52-R calipers also use standard D52 pads available in a range of compounds for every application. Caliper mounting uses the original GM stock height and offset. D52-R Caliper, also known as D52R Caliper, is the pinnacle design for OEM replacement racing calipers.
