SSBC-USA R6-Redline Caliper Upgrade Kits

SSBC-USA offers R6-Redline caliper upgrade kits for a variety of applications, including many Ford Mustang models from 2005 and up. These 6-piston, heavy-duty upgrades give your muscle car the stopping power and performance it needs. The lightweight front brake calipers are made from high-quality aircraft-grade T6061 billet aluminum and are designed to directly bolt onto your stock axle. R6-Redlines overpower the empty space behind your wheels, improving the overall look and style of either your everyday ride or prized custom build. The 6-piston calipers are a direct replacement for factory 2/4-piston front calipers. Kits include high performance severe-duty brake pads, all necessary hardware, and full instructions. Standard color options are clear anodized, red, and black.

Kit benefits:

* Ridiculous stopping power
* Up to 28 percent larger pistons over OEM
* Eye-popping looks
* Significantly upgraded safety
* Direct-fit (no brackets required)
* Bolts onto stock spindles with existing mounting hardware
* Works with factory hydraulics and ABS
* Faster braking response times
* Fits behind most factory wheels (18 in. or larger)
* Fully assembled and easy to install
* Simple Instructions for bolt-on Installation

Kit features:

* 2 calipers completely assembled with high-friction, low-dust semi-metallic brake pads
* 6 heavy-duty, large bore stainless steel pistons per caliper
* 5 bridge bolts per caliper for maximum stiffness
* 2 stainless steel pad pins per caliper
* 2 stainless steel anti-rattle pad clips per caliper
* 4 stainless steel bleeders per caliper
* 6 HD square-cut pressure seals and 6 dust seals per caliper (DOT design)
* 1 internal crossover O-rings per caliper for responsive flow
* 1 banjo bolt and brass block with compression washer per caliper
