This Wilwood Forged Dynalite Pro Series front hub kit pairs four-piston Dynalite calipers in red powder coat with an 11-inch drilled and slotted vented rotor for GM G-body cars that keep a factory disc spindle. The forged billet Dynalite serves as the base model in most of Wilwood's bolt-on disc brake kits. The manufacturer credits its stress-flow forging with keeping the metal's grain intact around the caliper body, which avoids the breaks in grain structure that machining a straight block billet creates. For a G-body owner moving off stock hardware, that means a larger rotor and a caliper built for repeated heavy stops, not just a cosmetic red upgrade. Searchers looking for a 79-87 G-body big brake kit, a red Dynalite 11-inch front conversion, or a factory-spindle drilled rotor setup will find this part matches that description.
Fitment is practical for a street-driven car. The manufacturer's listing gives a 14-inch minimum wheel diameter and zero OE hub offset, and the kit works with either manual or power boost master cylinders. Kits come complete with calipers, rotors, hub assembly, brackets and hardware. Plan on buying the 220-7056 hose kit as well, since the manufacturer lists it as required and it is the 14-inch domestic 3/8-24 IF length. Confirm wheel clearance before you buy, because the manufacturer advises checking the wheel clearance diagram in the kit installation instructions before purchase.
Yes. The manufacturer lists the 220-7056 line kit as required with this kit. Its hose kit is the 14-inch domestic length with 3/8-24 IF fittings, and the manufacturer notes the installer is responsible for routing the hoses so they clear moving suspension and wheel parts.
The manufacturer states that Pro-Series front kits work with either manual or power boost master cylinders, but it does not specifically address stock units. Confirm compatibility with the manufacturer before reusing your existing master cylinder.
The manufacturer lists a 14-inch minimum wheel diameter. Check the manufacturer's wheel clearance diagram against your intended wheel and offset before buying.
The manufacturer's front-kit instructions say installation should be done only by people experienced with disc brake systems, so treat this as an intermediate-to-advanced bolt-on rather than a beginner job. Work with the front wheels off the ground and support the lower control arms on jack stands rather than a floor jack. On some disc spindles, the factory caliper mounting "ears" interfere with the new bracket, and the instructions cover removing them. Verify the hub stud pattern matches your wheels, and set pad height by adding or removing shims between the caliper and bracket. Owners on user forums report that converting from stock often means forming or replacing some brake lines, so budget time for line work alongside the 220-7056 hose kit.
