Soueast Lioncel Big Brake Kit Upgrade / TTSPORT Classic 5420
The Soueast Lioncel was one of China's hottest budget tuner platforms roughly two decades ago — a front-wheel-drive compact sedan built around a 1.6L engine (99 PS at 6,000 rpm, 136 N·m at 4,500 rpm) that owners loved to push hard. This owner's brief was simple: sharpen the handling and shorten stopping distance, and do it without adding wheel spacers to clear the calipers. TTSPORT's TT5420 forged four-piston front kit checked both boxes.
The install list was straightforward: a TT5420 forged four-piston caliper, a 286x24mm high-carbon heat-treated curved rotor, and TTSPORT stainless steel brake lines — front axle only, fitted behind the car's factory 15-inch wheels with no spacer needed.
Vehicle & Kit Specs
| Item | Specification |
|---|---|
| Vehicle | Soueast Lioncel, FWD compact sedan, 1.6L engine (99 PS/6,000 rpm, 136 N·m/4,500 rpm), 15-inch factory wheels |
| Front caliper | TTSPORT TT5420 two-piece forged four-piston caliper, staggered piston bores |
| Front rotor | 286x24mm two-piece curved/slotted rotor with aluminum hat, high-carbon steel, heat-treated |
| Lines | TTSPORT stainless steel braided brake lines |
| Axle coverage | Front-only kit, no wheel spacers required |
Because the Lioncel carries its engine and transaxle up front, the front wheels do most of the braking work. That weight bias, plus the owner's budget, made a front-only TT5420 kit the sensible call instead of a full four-corner setup.
Clearance was confirmed with the stock 15-inch wheel back on the hub — no spacer, no rubbing, the exact outcome the owner asked for.
Why It Works
- Two-piece forged construction, CNC-machined and joined with high-strength bolts, cuts down on flex and vibration under hard braking versus a cast single-piece caliper.
- Staggered piston bores apply clamping force progressively — small pistons engage first, larger ones follow — for a more linear, predictable pedal.
- The two-piece rotor's aluminum hat trims unsprung weight, while the curved vane design improves heat dissipation and helps clear pad dust and debris from the friction surface.
The TT5420 is TTSPORT's split-forged small four-piston caliper, built from high-strength aerospace-grade forged aluminum and joined into a two-piece unit through precision coaxial CNC machining — improving durability without adding unnecessary weight.
The curved-slot two-piece rotor keeps the friction surface cleaner and cooler run after run, so the pad keeps better contact with the disc and braking stays consistent instead of fading off after repeated hard stops.
