120-6543-RS - Product Description

Billet Superlite 4R Radial Mount

This specially configured Superlite SL4R narrow body caliper features an increased bridge radius to allow proper pad alignment and bridge clearance for use with 13.00" to 14.00" diameter rotors. A special body design is used with 16mm pads to provide the narrowest possible profile for tight clearance applications. Radial mounting simplifies adaptation and provides two planes of adjustment for accurate alignment over the disc.

A key to the superior performance of the SL4R comes from the extremely durable, efficient and lightweight body design. Starting at 4.50 pounds it is the product of computer generated solid modeling and FEA stress analysis technology. A reinforced radial transition from the piston bore housings to the closed end bridges has produced the strongest SL caliper bodies ever built. Additional strength and resistance to deflection comes from the four high-strength steel end bridge bolts. A fifth center bridge bolt provides even more overall strength and easy access to the pads without the need to remove the caliper from the mount.

SL4R calipers come with machined aluminum pistons and rubber dust boots. Aluminum is lightweight with high resistance to corrosion and fast heat dissipation. The dust boots seal out debris to keep the pistons and caliper bores running smooth. High temperature square faced bore seals have the largest possible sealing area and provide controlled piston retraction. Three piston bore options are available to match the fluid and brake clamping bias requirements of any custom vehicle application.

Additional Notes

In addition, each SL4R is equipped with SRS bridge plates. SRS plates eliminate bridge wear caused by pad gouging. The spring-loaded action of the SRS plates also eliminates pad rattle and dampens pad squeal. Two piece bleed screws and dampened fluid tubes are recess mounted to shield them from track debris and other potential damage sources. A full range of brake pad compounds is available to match the brake response and heat range of any competition or sports driving application.
