Wilwood is pleased to announce their newly redesigned FNSL6R six-piston and FNSL4R four-piston model radial mount calipers. The narrow body Superlite calipers are prominent throughout the Wilwood Brake Kit product line, and well known in the motorsports aftermarket. This newest revision adds strength and durability to the caliper series through the use of superior stress flow forging processes and technology. Stress flow forged calipers add internal strength through improved material grain alignment within the caliper body. In addition to the structural improvements, the new FNSL calipers have also taken on the style and robust appearance of their bigger brothers in the W6AR and W4AR caliper groups. However, all mounting dimensions and the 7416 type pad applications remain the same as the previous BNSL series calipers.
The popular FNSL6R and 4R calipers used in most big brake upgrade kits are now available with our signature logo and either black or red gloss powder coat. Coming new in February 2012, FNSL6R and 4R calipers will also be available in our new nickel plated “Quick-Silver” series. Custom powder coating is also available on a per order basis.
The all new FNSL6R six-piston and FNSL4R four-piston calipers are now staged to be the strongest, most durable styled performance radial mount calipers ever offered in this popular intermediate size caliper series.
