Big Brakes. Plain and simple, that's what the SSBC-USA Extreme 4-piston brake upgrade kit is. The SSBC-USA Extreme 4-Piston series caliper uses four stainless steel pistons: either 38mm, 43mm or 48mm - depending on the application. Each caliper is constructed of lightweight aircraft quality aluminum to reduce unsprung weight and improve the ride quality. They are also clear anodized for an attractive look. The kit also includes stainless steel bleeder screws and uses stainless steel ARP bolts.
