The TTSPORT Evolution EB8 is a front 8-piston big brake kit engineered for drivers who need more thermal capacity, stronger pedal authority, and more repeatable stopping behavior than a factory caliper can deliver. Two-piece forged aluminum calipers, staggered 28/32 mm pistons, and 380–405 mm two-piece rotors give you bite without harshness and confidence lap after lap, stop after stop.
Two-piece forged aluminum body with eight pistons (28 mm × 4 / 32 mm × 4) and 56.8 cm² of total piston area per caliper. Staggered sizing distributes clamp force evenly across the pad, reducing taper wear and giving a linear, modulated pedal.
Two-piece pistons with thermal insulators and dust boots slow heat transfer from pad backing to brake fluid. The result: less fade on long descents, track sessions, and repeated high-speed stops.
Internally vented Ø380 or Ø405 mm rotors with CNC-machined aluminum hats. Choose heat-treated high-carbon iron or carbon-ceramic composite to match your driving range and service expectations.
Large piston area combined with matched pad compounds delivers strong initial bite while keeping threshold braking controllable — important on street, canyon, and trackday duty cycles.

Pad compound is matched to rotor material. Iron/steel pads run only with iron rotors; carbon-ceramic pads run only with CCB rotors.
Two forged 8-piston front calipers.
Complete brake pad set for both front calipers.
Two two-piece rotors in your selected size and material.
Two CNC carbon-steel mounting brackets.
Two CNC aluminum hats.
Two PTFE/SUS304 stainless braided brake lines.
The EB8 is a platform-adapted big brake kit, not a universal one-bracket-fits-all assembly. Confirm these items against your vehicle and wheel before purchase.
Confirm you are running 19 in or larger wheels.
Measure spoke clearance before ordering. The EB8 requires at least 107 mm of minimum spoke clearance.
Confirm hub, knuckle, caliper bracket compatibility, brake line fitting type, and rotor diameter selection before placing the order.
Need a clearance check? Contact us with your vehicle, wheel spec, and intended use before placing the order.
The EB8 is platform-adapted with vehicle-specific brackets and brake line fittings. Contact us with your year, make, model, and wheel specification so we can verify caliper clearance, bracket availability, and rotor size before you order.
19-inch wheels or larger are required, with at least 107 mm of spoke clearance. Wheel offset and spoke geometry both matter — send us your wheel details if you are not sure.
380 mm suits most street and spirited driving builds. 405 mm adds swept area and thermal mass for heavier vehicles, frequent high-speed stops, or trackday use. Both run a 34 mm rotor thickness.
Iron/steel rotors are cost-effective, easy to service, and run pads with a 0–600 °C range and μ ≈ 0.38. Carbon-ceramic rotors are lighter, last longer under heavy use, and pair with pads rated 0–700 °C and μ ≈ 0.45. Pads must match rotor material.
Two forged 8-piston front calipers, two two-piece rotors in your selected size and material, matched brake pads, CNC aluminum hats, CNC carbon-steel mounting brackets, and PTFE/SUS304 stainless braided brake lines.
Yes. A proper bedding-in procedure is required to transfer pad material onto the rotor face and stabilize the friction couple. Skipping bed-in will cause uneven deposits, vibration, and reduced bite.
Send us your vehicle, wheel, and use case. We will confirm fitment, recommend rotor size and pad compound, and quote the right configuration.
