• Brand New Wilwood Open Wheel Rear Inboard Brake Rotor for Sprint Cars, Midgets, etc. (Part # 160-5865) | > .810" Thick > 12.19" Outside Diameter > 8 x 7.00" Bolt Circle > Drilled for lower rotating weight > Weighs 8.0 lbs > High-tech racing design > High quality, high temperature steel construction > Precision machined When it comes to rotors, racers are constantly searching for the ultimate balance between the lowest weight and the ability to effectively manage heat | * Decreased rotating weight in the drive line provides quicker deceleration under braking and quicker acceleration out of the corners | * Lower weight also benefits handling with improved spring and shock control over the unsprung suspension mass Wilwood's ULD - 32 drilled iron rotors provide a highly effective lightweight option for many forms of competition applications that race in low to medium temperature ranges ULD - 32 Series Drilled Straight Vane Vented Rotors feature a two row, 64 hole pattern that alternates between and directly over each vane | * Each hole is deeply chamfered to eliminate any stress points that could result in premature cracking at the drill holes | * The drilling process removes an average of one pound from each rotor | * Rotating and unsprung rotor mass is reduced by as much as 12% Caution on drilled rotors: | * There is a common mis-perception that rotors are drilled to improve cooling | * The reduced mass of a drilled rotor will dissipate its retained heat quicker, but it also builds up heat at a much faster rate | * The decision to use drilled rotors should be solely based on the merits of the lower rotating and unsprung weight, and not for improved cooling
