The Wilwood Forged Dynalite Pro Series front kit (MPN 140-11018-DR) is a 1987–1993 Mustang big-brake conversion built around Dynalite calipers with 4 red powder coat pistons and an 11.00 rotor, with the kit mounting to the factory disc spindle. Wilwood describes the hub assembly as lightweight aluminum, and the drilled and slotted vented rotor is the feature that separates this from the undrilled "-R" version. Compared with stock front brakes, the larger rotor and four-piston caliper give more pad contact area and clamping force for repeated hard stops, which justifies the price for track days, autocross, or heavier street use. Choose this kit over a budget rotor-only swap if you also want the 5-lug hub conversion in the same package. Search terms this kit matches include 1987-1993 Mustang 5 lug big brake kit, Fox Body 11 inch front brake conversion, and red Dynalite 4 piston calipers.
The manufacturer lists the kit for Ford Mustang 1987-1993 applications, and it is a five-lug configuration only, so it will not accept 4-lug wheels. The kit is sold without its brake line set, since a line kit (220-6471) is needed to complete the install. Buyers should plan for spindle work and confirm the bolt pattern before ordering. The manufacturer's assembly sheet for a sibling 87-93 V8 hub kit notes that installation requires spindle modifications that are best accomplished by a qualified machine shop. Wheel clearance also needs checking against the manufacturer's wheel clearance diagram before you buy wheels.
No. The manufacturer lists this kit as five-lug only, so a 4-lug hub setup is not supported.
Yes. The manufacturer lists a separate line kit (220-6471) as required, and it is not included in the box.
The manufacturer lists 1987–1993 Ford Mustang models with the V8 disc spindle. Confirm your spindle type before ordering, because 1987–1993 spindles differ from earlier ones.
Installers report varying difficulty ratings for this kit, so confirm the install approach with the manufacturer before starting. The manufacturer's instructions for a related 87-93 Mustang hub kit say the installation should be done by persons experienced with disc brake systems, and that spindle modifications are best handled by a machine shop. Plan on a full brake teardown to bare spindles, a wheel-clearance check, and a brake line kit purchase. Use the manufacturer's install sheet and wheel clearance diagram before you start.
