P42 is the lightest four-piston caliper in TEI's Street Tuned range at 2.8kg, built for small-displacement A- and B-segment sedans and compact SUVs that see occasional track days alongside daily driving. Four opposed pistons spread 49.47cm² of clamping area across a two-piece forged body for a firmer, more linear pedal than the factory caliper it replaces.

Fits 15–16-inch wheels. Includes caliper, rotor, brake pads, and mounting hardware.

What you feel at the pedal

Same push of the pedal. Two different brakes.

Floating caliper

Pedal
Grip on the rotor
Body is still slidingFull grip

You press the pedal. The brake first moves one pad, then slides its whole body, then grips.

You wait for two steps.

TEi BRAKES Fixed caliper

Grip on the rotor
Full grip

You press the pedal. Pistons on both sides move together. The brake grips straight away.

You get one direct step.

New emblem. Better rotor.

Same TEi, one generation on. Here is what changed on the kit we ship today, and what it does for your braking.

Drag to compare

Rotor face
Slotted only was cross-drilled and slotted

No drill holes, so there is nowhere for a crack to start.

Material
G3500 high-carbon alloy, 3.85% carbon

Built for longer disc life.

Cooling
72 vent grooves, rated to 600 °C

More channels to move heat out of the disc, lap after lap.

Finish
Anti-rust black coating was bare metal

Resists rust, so the rotor looks right between sessions.
