The popularity of aggressive fitting wheels on factory body vehicles has never been more popular than it is today. In most cases, aftermarket big brake kits aren?t compatible with this style. Large multi-piston brake calipers just don`t fit within the very limited spacing between the larger brake caliper and the back of the wheel. Ksport has developed the Slimline Caliper with this issue in mind, a design that?s based on the OEM single-side piston caliper thickness. Ksport`s new caliper design ensures that you can use the Slimline Brake Kit on most factory wheels, or wheels with very limited brake caliper clearance.
