Wilwood 140-15345 Billet Dynalite 11.75" Slotted Radial Mount Sprint Car Inboard Left-Hand Brake Ki

The Billet NDLR caliper is a compact, lightweight, and rugged caliper that provides strong clamping force from four stainless cup pistons. The bodies are fully CNC machined from billet with internal fluid ports that eliminate external fluid tubes. Each caliper is equipped with two corner bleeds and outboard inlets in the correct location for a standard Inboard mount. The bridges are equipped with stainless steel anti-rattle wear plates. These plates reduce bridge wear and provide smooth, rattle free operation of the pads. A center bridge bolt adds overall caliper strength and positive retention of the top loaded pads.

All Billet NDLR calipers are designed for long service using the 0.63” (16,0 mm) thick 7816 style brake pads. These pads are available in many different PolyMatrix compounds to provide the correct brake torque and heat range for any high performance or competition application. Radial mount bracket kits are used to install a radial mount caliper in place of a tab mount caliper. Brackets are available for both Sprint and Midget Inboard and Dirt Late Model applications for various rotor diameters.

Wilwood's newest Super Alloy rotor in 11.75” diameter is targeted directly to Dirt Late Model and Modified racing. Wilwood’s proprietary Super Alloy material provides the lowest rotating and un-sprung weight, without degradation, shrinkage and warping like comparable Iron & Steel lightweight rotors. Super Alloy rotors provide a durable lightweight option in applications where sustained temperatures remain in the low to moderate range, and high heat spikes are only observed on an intermittent basis. Our special alloy and proprietary manufacturing processes give these rotors high resistance to thermal distortion with excellent friction and wear characteristics against the pads.

Wilwood's Gen II Sprint inboard hub & adapter kit provides a basis to provide dynamic rotor mounting of either standard 6 x 5.50” or 8 x 7.00" bolt pattern rotors. Hub & adapter kits contain: rotor adapter and dynamic rotor mounting bolt kit. Manufactured from high strength aluminum, it provides a lightweight and strong solution for rotor mounting. Gen II hubs offer improved clearance and easier install due to widening of the rotor adapter attachment bolt spacing. Additional T-nuts and bolts are required rotor mounting and are not supplied with the clamp kit.
