How they work
Titanium conducts heat poorly – roughly 6.7 W/m·K for Ti-6Al-4V versus about 52 for steel and 130 for aluminum – so far less braking heat reaches the pistons, seals, boots and brake fluid. Short term: helps prevent boiled fluid and a long, soft pedal when the brakes are at their thermal limit. Long term: extends piston seal and dust boot life, so caliper rebuilds are needed less often. Water-jet cut to the exact pad shape – drop-in, with no cutting or grinding.
The shape number matches the industry pad shape for your caliper. If you are unsure which caliper your car has, contact PHD Racing with your VIN before ordering.
