Big brakes built for a small, momentum-driven car. This TTSPORT Direct-Mount Series front big brake kit is engineered specifically for the Honda Fit / Jazz around the WD4 forged 4-piston caliper, a Ø262 mm × 21 mm internally vented rotor, and vehicle-specific brake line fittings.
The factory front brakes work for stock pace, but once you add stickier tires, run canyon roads, or push autocross laps, they become the limit. This kit raises that ceiling with a stiffer forged caliper, more piston area, a larger rotor, and a firmer pedal—without forcing you into a 17-inch wheel.
Bolts to the factory Fit / Jazz front knuckle. No brackets, no adapters.
WD4 forged 4-piston caliper with 38 mm pistons and 45.4 cm² total piston area per caliper.
Ø262 mm × 21 mm vented disc gives a real heat sink without overloading the front suspension or wheel.
Three-layer SUS304 braided lines with PTFE liner and PVC sheath, fittings sized for both chassis and caliper.
Designed to clear common 15 in wheels with 42 mm minimum spoke clearance.
Stiffer than cast OE calipers, so pedal travel goes into the pads—not into caliper flex.

Confirm your Honda Fit / Jazz chassis code, front wheel diameter, and at least 42 mm of spoke-to-caliper clearance before ordering. Wheel offset and spoke shape change real clearance.
Two WD4 forged 4-piston front calipers.
Brake pads for both front calipers, rated 0–600 °C and intended for iron / steel rotors.
Two Ø262 mm × 21 mm one-piece vented directional rotors, left/right specific.
Stainless-steel braided brake lines with vehicle-specific fittings for Fit / Jazz.
Before ordering, confirm your chassis code, front wheel diameter, and at least 42 mm of spoke-to-caliper clearance. Wheel offset and spoke shape change real clearance.
15 in or larger wheels are required.
Minimum spoke clearance: 42 mm to the caliper face.
Confirm Honda Fit / Jazz chassis code: GE / GG, GK / GH / GP, or GR / GS.
Wheel offset, spoke shape, and barrel design all affect real-world clearance. We recommend checking with a caliper template if you run aggressive wheels.
This WD4 Direct-Mount front big brake kit is engineered for Honda Fit / Jazz chassis codes GE, GG, GK, GH, GP, GR, and GS. Confirm your chassis code, front wheel diameter, and minimum spoke clearance of 42 mm before ordering.
15 in or larger wheels are required, with at least 42 mm of spoke clearance to the caliper face. Wheel offset, spoke shape, and barrel design all affect real-world clearance, so a caliper template check is recommended for aggressive wheels.
The kit includes two WD4 forged 4-piston front calipers, brake pads for both front calipers, two Ø262 mm × 21 mm one-piece vented directional rotors, and stainless-steel braided brake lines with vehicle-specific fittings for Fit / Jazz.
Yes. The calipers are direct-mount to the factory Honda Fit / Jazz front knuckle. Brake line fittings are vehicle-specific on both the caliper and chassis side, and a proper bedding-in procedure is required after installation.
No. The WD4 front calipers use aluminum-alloy pistons without dust boots. Inspect and clean the piston area during regular service, especially after rain, track use, dust, or salted-road driving.
Compared with the factory front brakes, the WD4 setup adds a Ø262 mm × 21 mm rotor, 45.4 cm² of total piston area per caliper across four 38 mm pistons, and a stiffer two-piece forged aluminum caliper body for firmer pedal feel and improved fade resistance under repeated hard stops.
Yes. Custom caliper colors and finish options are available for this kit. Contact TTSPORT before ordering to confirm lead time and pricing.
