Where's your steering arm?
The DS-999 brackets go on the front or back of the spindle for the listed applications. Mock it up before you tighten anything. The drawing shows one Camaro, not every car in the table.
Fitment
Exact manufacturer applications include specified Buick, Chevrolet, GMC, Oldsmobile and Pontiac factory-spindle combinations, plus listed Ford/Mercury and other applications requiring Ridetech Pin Spindles.
The vehicle year alone is insufficient. Match each exact application's disc/drum spindle, trim and Ridetech-spindle condition. Unlisted aftermarket spindles and suspension swaps require separate confirmation.
Specifications
Part 140-13203-D; black four-piston Dynapro Dust-Boot calipers, BP-10 pads, and 12.19 x 0.81-inch SRP drilled/slotted iron rotors with black electro-coat.
Published hub offset increases track width 0.19 inch per side. Aluminum hubs have 5 x 4.50 and 5 x 4.75 bolt circles with 1/2-20 studs.
Dust-boot sealed pistons suit the manufacturer's low-to-intermediate-temperature applications; no unrestricted high-temperature racing claim is made.
Included
Caliper and rotor pairs, hubs, rotor adapters, mounting brackets, BP-10 pad set, inner/outer bearing cones, grease seals, spindle washers, dust caps/O-rings, studs, shims and listed hardware.
Before ordering and installation
Check DS-999 Figure 2 before choosing wheels; maintain its minimum 0.080-inch wheel-to-caliper clearance. Some 15-inch wheels fit, subject to the template.
Inspect the upper anchor-pin and lower bracket/steering-arm holes. Some listed spindles require DS-999 Figure 3 drilling/tapping/countersinking and a 0.50-inch lower hole; a qualified machinist should perform the required work.
Use the specified disc-spindle spacer and matching hardware where required. Check bracket orientation and clinch-nut engagement after shimming. Retain OEM spindle nuts/locks; new cotter pins are separate.
Overhanging wheel contact surfaces require separate 300-11961 spacers; stamped steel wheels without overhang should use separate 300-10716 hub shields. Check the added track width against fender and tire clearance.
Flex lines are not included. The caliper inlet is 1/8-27 NPT; Wilwood lists 220-7056 on the product page, but line length/fittings and full-travel routing must match the actual car.
Confirm master-cylinder and proportioning requirements for the full brake system. Bleed, bed, test and inspect using DS-999 before driving.
