Paragon PPS1313 titanium brake pad shims fit BMW F87 M2 / F80 M3 / F82 M4 using the rear brake application listed below. They sit between the pad backing plate and caliper pistons to limit heat transfer into the caliper and brake fluid.

How titanium shims help
Titanium’s low thermal conductivity makes the shim a thermal barrier between a hot brake pad and the caliper piston. This supports heat management during repeated braking, alongside suitable pads, rotors and fresh brake fluid. It does not change pad compound or replace the need for adequate cooling.
Before installation
Blue factory calipers with 370x24mm rear rotors. Confirm the backing-plate outline and piston-contact area. Account for the additional 0.5mm thickness per shim, and check pad movement and available clearance during installation. These shims are not a universal fit based on vehicle model alone.
Inspect brake-fluid condition and the complete braking system before track use. Have the work completed by a qualified installer.
Product FAQs
What is included with PPS1313?
A set of four 0.5mm Grade 5 titanium shims for one axle.
Will these shims fit my calipers?
Blue factory calipers with 370x24mm rear rotors. Match the shim outline to the pad backing plate and confirm installation clearance.
Do titanium shims prevent all brake fade?
No. They limit heat transfer at the pad-to-piston interface. Pad temperature range, rotor cooling and brake-fluid condition still matter.
