Big Brake Kit Upgrade / TTSPORT Slim Series
Most big brake upgrades force a trade-off: bigger rotors and calipers usually mean wheel spacers, or worse, a trip to the wheel shop for a new set that will actually clear the new hardware. TTSPORT's newest kit skips that compromise entirely — it's built to slot in behind the factory 17-18 inch wheels already on the car, no spacers, no re-fitment headaches.

The whole point of this release is fitment: a kit that upgrades braking hardware without pushing the wheel out or requiring an offset change. That's a real engineering constraint — the caliper and rotor package has to grow in stopping power while staying inside the same wheel envelope the car left the factory with.
Vehicle & Kit Specs
The release focuses on wheel-fitment performance rather than a single vehicle application, so the table below reflects what's confirmed about the kit itself.

| Front caliper | TTSPORT performance caliper, engineered for OEM wheel clearance |
| Front rotor | TTSPORT performance rotor, sized for direct-fit installation within factory wheel offset |
| Bracket | Vehicle-specific caliper bracket, no offset or spacer adjustment needed |
| Pads / lines | Included in the kit |
| Hardware | Fluid, bolts, and mounting hardware included |
Why It Works

Keeping the original wheel in play isn't just a cosmetic win. Spacers push the wheel further outboard, changing scrub radius and adding leverage on the wheel bearing and hub — small changes that add up over time. A kit designed to clear the stock wheel without a spacer keeps the factory track width, bearing load path, and steering geometry exactly where the manufacturer engineered them.
- No spacers means no change to wheel offset, scrub radius, or bearing load
- Fits inside the factory 17-18 inch wheel, so there's no need to size up wheels to run bigger brakes
- Bolt-in installation keeps the job straightforward for shops working within a set budget and timeline
