A single piston acts on the inner pad. The caliper body then slides on its guide pins to bring the outer pad into contact.
Two sequential steps create dead travel and a slight delay in pedal feel.

Larger rotors, same four-piston body. The P40NS+ pairs TEI’s Street Tuned four-piston caliper with 330mm or 355mm discs, taking the P40NS platform up to 18-inch wheels.
Four opposed pistons spread 49.56cm² of clamping area across a 3.2kg two-piece forged 6082-aluminium body. That combination gives pedal feel comparable to six-piston kits at roughly half the weight, and clears most factory 17- and 18-inch wheels without spacer rings.
Choose 17-inch wheels with 330×28mm rotors, or 18-inch wheels with 345×28mm or 355×28mm rotors. Every kit includes caliper, rotor, brake pads, and mounting hardware. Replacement pads and rotors stay stocked for the life of the platform.
Every TEI kit is custom-built — bells and brackets machined for your vehicle — and ships directly from our Guangzhou facility. Steel-disc kits typically ship in 2–3 weeks, plus transit time; exact times for your destination are shown at checkout.
We ship worldwide by express courier with tracking, and you're welcome to use your own freight forwarder — just send us the warehouse contact and reference number before dispatch. Import duties and taxes, if any, are set by your customs authority and are the recipient's responsibility. See our Shipping page for full details, or contact us for a shipping estimate before ordering.

See why a fixed multi-piston caliper delivers a more direct, linear pedal feel.
A single piston acts on the inner pad. The caliper body then slides on its guide pins to bring the outer pad into contact.
Two sequential steps create dead travel and a slight delay in pedal feel.
Pistons on both sides move directly and at the same time, clamping the rotor in one controlled step.
Clamping force F = P × S: hydraulic pressure multiplied by total piston area. The response is direct and linear.
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
No drill holes, so there is nowhere for a crack to start.
Built for longer disc life.
More channels to move heat out of the disc, lap after lap.
Resists rust, so the rotor looks right between sessions.
