Jaguar XFL Big Brake Kit Upgrade / TTSPORT Classic 8703
The Jaguar XFL leans into a sporty positioning, offered with a 2.0T in two states of tune and a 3.0T supercharged V6 shared with the F-TYPE, all backed by an 8-speed automatic. Whatever engine is under the hood, the factory brakes on a car like this are built to a cost target, not a track target. This case swaps the front stoppers on a 19-inch-wheel XFL for a TTSPORT Classic 8703 forged six-piston caliper matched to a 380mm x 34mm drilled rotor.
The TT8703 is a forged six-piston caliper finished in silver — a clean, high-end look behind the spokes. Paired with the 380mm drilled rotor, the front wheel fills out noticeably compared to the stock setup, and the brake package reads as a real upgrade rather than a cosmetic swap.

Why It Works
- A forged six-piston caliper is stiffer than the stock sliding caliper, so pedal effort goes into clamping the pad instead of flexing the caliper body — that's what firms up pedal feel.
- Stepping up to a 380mm x 34mm rotor adds swept area and thermal mass over the factory disc, which helps the system shed heat on repeated hard stops.
- The larger rotor and caliper still tuck behind the XFL's stock 19-inch wheels, so the upgrade fills out the wheel visually without forcing a wheel change.
Six pistons spread clamping force across a larger pad, which helps keep pressure even on the rotor face and supports more consistent bite as the brakes heat up during hard driving.
