Detailed instructions make the installation straight forward requiring average abilities and tools.

Wilwood Calipers for the 65-82 Corvette Kits:

Front: SL6R

The Wilwood SL6R caliper is a forged billet, 6 piston, mono-block type caliper. The forged billet aluminum material provide super strength and are ultra light weight (4.8pounds) making them the lightest of ANY caliper readily available today for the C3. Wilwood’s “Differential Bore Design” utilizes special stainless steel piston dimensions and location for optimum brake pad balance and wear. The stainless piston helps prolong heat transfer to the fluid and resist corrosion. Wilwood’s extensive racing heritage has yielded the finest caliper for the Corvette. The SL6R Caliper is Black or can be up-graded to a Red finish. In kit form, the caliper has the Wilwood DP-20 pads which are an aggressive street or track time material. A full line of Wilwood or Hawk pads are available.

Rear: SL4R

Wilwood’s racing heritage continues in the rear 4 piston, forged billet, mono-block style caliper for the 65 to 82 Corvette. Again, the lightest rear caliper (4.6lbs.) available, this caliper uses stainless steel pistons and designed for performance. Mounting in the original location, this caliper facilitates no restriction of the parking brake components, easily accommodates either a 13″ or 14″ rotor.

Wilwood 2 Piece Rotors for the 65-82 Corvette Kits:

Front & Rear:

In the Wilwood “Big Brake” kit for the 65-82 Corvette are options, 13″ or 14″ diameters, slotted or cross drilled and slotted. All rotors are of a 2 piece design, black anodized aluminum “hats” or centers, using air craft securing fasteners for maximum strength and durability. In the standard kit, “black calipers” the rotors are slotted and un-coated. The slotted rotor extends rotor life, maximum pad sweep surface, while providing a channel for pad off gassing and water film during braking. Un-coated for maximum breathing, these are intended for racing.


The cross drilled and slotted rotors are available in 13″ or 14″diameter and also of the 2 piece design. They are E-Coated for reduced corrosion and a sporty street look.

Additionally, the rear rotors are designed to utilize the factory parking brake with no modifications.
