Show original supplier description

The Project Mu Forged Sports Brake Caliper Kit offers a premium brake upgrade with a 4-piston, 4-pad configuration. It is available in a variety of custom colors, including Red, Orange, Yellow, Silver, and Black, each with a clear, heat-resistant coating. This comprehensive kit includes everything needed for installation: two calipers, two aluminum caliper brackets, four brake pads (two per caliper), two two-piece rotors measuring 345x32mm, two Teflon brake lines, and all necessary brake pad springs and installation parts. The use of forged materials and a multi-piston design aims to provide superior stopping power and heat dissipation compared to stock braking systems. Some kits for specific vehicles may be made-to-order, so it is advisable to confirm availability prior to placing an order if lead time is a concern. The typical shipping time after payment is approximately 19 days. This kit is designed for front axle fitment on the Acura NSX NA1 (1991-1996) and NA2 (1997-2005) models.
