With a Drive Output Thread of 7/8-18 and a square of 0.112-inch, the SpeedBox offers flexibility. Its calibration range from 170-1,650 turns per mile ensures precision for diverse speedometers. With its versatile design, the box can be efficiently installed either on the dashboard or under the hood. The default is calibrated for U.S. speedometers at 1,000 turns per mile, and it adapts effortlessly to signals from GPS or VSS (Vehicle Speed Sensor), automatically calibrating with the included GPS antenna.

Wilwood has expanded the lineup of rear disc/drum brake options for GM G-body vehicles equipped with 7-1/2-inch or 7-5/8-inch rear differentials. Popular G-body models include the Chevy Monte Carlo, Malibu, and El Camino. New 12.88- and 14.00-inch brake kits were designed around Wilwood’s motorsports-proven rigid Superlite four-piston calipers with two large rotor options and join previously released 11.00-inch DynaPro and 12.19-inch Dynalite brake kits.

A two-piece aluminum hat-to-rotor combination houses an internal drum parking brake assembly to retain the OE feature. The rotors are Wilwood’s proprietary Spec37 iron alloy with curved vanes, 48 in the 12.88-inch kit and 72 in the 14.00-inch kit, and both sizes are E-coated with your choice of GTB slotted or SRP drilled-and-slotted faces. Forged Superlite FNSL4R radial-mount calipers are Type III hard anodized for durability with stainless steel pistons. Colors are gloss red or black powdercoat or 26 optional colors (additional charges apply). The brake pad compound is Wilwood’s BP-10 street performance, or choose from many other available frictions for your application.
