Zero Offset® ZZ1 Kits

ZZ1 and ZZR Zero Offset® Brake Kits™

We started designing these Zero Offset® brake kits back in the late 90's to move the wheels where they were with stock drum brakes. There is nothing that looks worst that a vintage car with late model looking wheels. Every muscle care needs the reverse rim look not matter what diameter wheels you are have. We have since developed our own design hubs and spindles to solve the problems associated with aftermarket and stock spindles and hubs. We are leaders not followers so, we started with a clean sheet of paper. You no longer have to wait for quality brake related parts. We have filed our patents on only a few inventions. As our patents are filed, the parts will be available to the public. All parts are made and assembled in the USA by American citizens.

ZZ1 Kits: Zero Offset® aluminum hubs, black anodized aluminum hats, 1.10", 1.25" and 1.38" thick slotted and balanced rotors, bearings, seals and grade 8 hardware for safety wire. 3" wheels studs available upon request at no additional charges. Kits require our Zero Offset® spindles and caliper brackets made for the 3.5", 5.25" and radial mount. Designed for all Wilwoods and specific AP Racing, Coleman and Outlaw calipers. We will custom build brackets to fit your existing calipers upon request. (See Caliper Brackets)

We made the spindles fit the brake kits, instead of making the brake kit fit the spindles. Our Patent Pending design Zero Offset® spindles come with a 1" to 2" drop and utilizes custom hubs with 25% larger bearings. Guaranteed give you the most tire clearance with our "Less than Zero" track width. All this design on the latest CAD programs for optimum suspension and steering.

ZR1 Kits: Medium to Heavy Duty Race Kits with same components as our ZZ1 kit except with heat treated floating rotors. Not intended for Extreme Duty i.e. short track asphalt.

Caliper kits include: 2 calipers and grade 8 hardware. The Zero Offset® ZZ1 Platinum Brake Kits are designed to be used with 1.10" to 1.38" rotors, they do not come in the smaller 0.810" and 1.00" wide rotors. For kits using stock or aftermarket spindles see our older standard Zero Offset® Kits (ZO1).

Pads include: Street or Performance pads for two (2) calipers.

Spindles include: Our Patent Pending Zero Offset® Spindles with 1" to 2" drop, Ackerman correct bolt on steering arms, spindle nuts and spindles washers. The amount of drop depends on the upright height of the spindle.

Caliper Brackets: Caliper brackets made for specific AP, Coleman, Outlaw and Wilwood calipers. Send us the specifications of your existing caliper and we will build a custom bracket for an upgrade charge.

Zinc coated rotors
