MAF Racing Bumper supports are on some of the baddest Mustangs around.

The formula for success sounds simple: Build power then cut weight=win races. Power to weight ratio has been the secret sauce to most racing victories. Building horsepower is expensive, but cutting weight without compromising function doesn’t have to be. 30% weight loss can be achieved with our mustang front and rear tubular bumper products. Made from Docol R8 alloy, most products require little to no modification to install, with instant weight reduction. When every pound matters, count on MAF tubular bumper products to provide the advantage you are looking for.
