4 Piston Calipers



The four piston calipers are suitable for a wide range of uses, both on the front and rear. Upgrading from your standard 4 piston caliper on the front to the ISR caliper represents the most cost effective performance upgrade you can make where the outright power of a 6 piston caliper is not needed. All four piston calipers are two piece construction.

If you don't see something to suit your requirements, or you want some advice or information about suitability or fitting, please contact us.

Please remember...

When ordering calipers you need to tell us which side the caliper mounts because all designs have left and right hand versions.

When replacing your calipers we recommend that you upgrade to a quality brake line to get the best out of the increased braking performance. It will help to transmit more power from the master cylinder to the caliper.
