Honda Civic (10th Gen) Big Brake Kit Upgrade
The 10th-generation Honda Civic built its reputation on the L15B8 1.5T engine — 130 kW and 220 Nm from a small-displacement turbo four that still runs on regular 92-octane gas. Owners who lean on that power quickly run into a familiar limit: the stock rear rotors are sized for a commuter car, not a car people are tracking or driving hard on mountain roads. TTSPORT's answer is a rear-only big rotor kit built specifically for the 10th-gen Civic — a 325 x 10mm two-piece rotor paired with a caliper relocation bracket that keeps the factory caliper in its stock position.
This isn't a swap to a new caliper family — it's a rotor upgrade that lets the factory rear caliper clamp a bigger, heavier disc. TTSPORT machines a custom hat to match the Civic's hub and pairs it with a relocation bracket, so the whole assembly bolts into the OEM caliper mounting position without cutting knuckles or trimming anything.

Why It Works
A bigger rotor does two things at once: it moves braking force further from the axle centerline, which increases effective clamping torque for the same caliper pressure, and it adds mass and surface area that soak up and shed heat faster than a smaller stock disc. That's why a rear rotor upgrade alone can noticeably firm up pedal feel and reduce fade on repeated hard stops, even without touching the caliper.
The two-piece design also matters: separating the aluminum hat from the iron rotor ring lets the disc expand and contract with heat independently of the hub, which cuts down on warping compared to a solid one-piece rotor. And because the bracket is machined to put the caliper back exactly where Honda put it, there's no spacer stack-up to fight with wheel clearance.
- Larger 325mm diameter increases braking leverage over the stock rear rotor
- Bolts to the factory caliper mounting point — no cutting, no spacers
- Two-piece hat-and-ring construction resists heat-driven warping
