Our Titanium Thermal Barrier Plates for the E30 M3 are designed to help optimize your M3's braking performance. While a certain amount of heat is required for brake pads to work properly in performance applications, that heat bleeds from the pads and rotors into the rest of your braking system.
This pair of thermal barrier plates is for the front of all E30 M3 with stock/original brake calipers, as found on all 1987, 1988, 1989, 1990 and 1991 model E30 M3.
Excessive heat causes braking performance to go down and is noticeable (and dangerous) as the pedal gets softer when the fluid boils. Even before the fluid gets hot enough to fully reach its boiling point, performance is decreased due to increased compressibility. In a street caliper, this heat will melt the caliper dust boots, requiring more frequent rebuilds.
Our BimmerWorld E30 M3 Titanium Thermal Barrier Plates are the perfect solution. Titanium has only 40% or less of the thermal conductivity of the steel material used for brake backing plates. Placing these thin 6AL-4V titanium plates between the brake pad and caliper piston will reduce heat transfer by approximately 70 degrees, giving your braking system more heat capacity and longer intervals between rebuilds. This is not Grade 2 Ti like other brands that can be purchased for 1/3 of the price - this is the good stuff! A must for track use - especially in heavier, full-interior street cars and stock and prepared class racers.
Sold in axle sets (one plate per caliper). Rattle clips must be removed for proper fitment. Recommended for use in both front and rear axles.
