Big Brake Kit Upgrade / TTSPORT Classic 5440
The TTSPORT 5440 has become one of the brand's steadiest sellers, and it's easy to see why: solid pricing, quick availability, and performance that holds up kit after kit. It's built as a straightforward upgrade path for drivers who want more consistent braking than a stock setup can deliver, without chasing an exotic or hard-to-source part number.
Kit & Fitment Specs
Here's the hardware breakdown for the 5440 front kit as fitted in this case.
| Item | Specification |
|---|---|
| Fitment | Compatible with most vehicles running 17-inch wheels or larger |
| Front caliper | TTSPORT 5440 four-piston, two-piece forged aluminum body |
| Piston area | Approx. 36.0 cm² × 2 / 41.3 cm² × 2, net weight approx. 2.66 kg per caliper |
| Front rotor | 330mm or 345mm × 28mm, two-piece cast rotor with aluminum hat |
| Pads | Brake pad friction area approx. 50.0 cm² |
| Rotor finish | Heat-treated friction surface with anti-rust coating; drilled or slotted face optional |

Why It Works
The two-piece forged aluminum caliper body resists the flex a single-piece stock caliper can develop under hard braking, which keeps pedal feel firm and predictable instead of going soft as the pads bite down.
The rotor pairs a cast iron friction ring with an aluminum hat, and the friction surface is heat-treated for a higher, more stable coefficient of friction along with better wear resistance. An anti-rust coating on the rotor face helps it stay clean-looking between use, and drilled or slotted patterns are available if a buyer wants extra bite or surface cleaning.
- Four-piston, star-profile racing pistons spread clamping force evenly across a roughly 50.0 cm² pad face
- 330mm or 345mm × 28mm rotor sizing is matched to fit inside a 17-inch wheel with the friction surface filling most of the visible wheel opening
- Radial-mount caliper design with vehicle-specific brackets keeps the setup a straightforward bolt-on for most applications
