The SR8 is TEI's Street Tuned S-series pick for EVs, large SUVs, and executive sedans running large-diameter factory wheels — comfort- and durability-oriented like the rest of the S-series, sized for vehicles where extra mass meets high-speed capability. An eight-piston, two-piece forged caliper spreads braking force across a 60.41cm² piston area, with internal fluid routing that keeps the fluid path shielded inside the caliper body rather than exposed to road debris and impact.

Fits 19–21-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.

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.
