BYD Destroyer 05 Big Brake Kit Upgrade / TTSPORT Slim SL6
BYD's Destroyer 05 is a hybrid built for daily commuting, and the factory brake tune reflects that: soft, comfort-biased, and not really sized for hard use. Push the pedal on a long downhill or a spirited backroad and the stock setup gets vague fast — exactly the kind of "can't stop in time" scenario that makes a brake upgrade worth doing before you touch anything else on the car. This build swaps in a TTSPORT Slim Series SL6 six-piston kit up front, on the stock 17-inch wheels, with no spacers.
The owner kept the factory 17-inch wheels for this install — no wheel swap, no spacer, just a direct-fit caliper and rotor package sized for the car's original brake geometry.

The Slim Series was built specifically for cars that need to stay on their factory wheels. Engineers tested the SL6 caliper's outer profile against the inner diameter and spoke clearances typical of 17-18 inch wheels, so it bolts straight in without a flange adapter or spacer.
Why It Works
- Direct fit on the stock 17-inch wheel — no adapter, no spacer, no wheel change required.
- Piston sizing was matched to the factory master cylinder, so pedal travel stays predictable — no dead spot or "grabby" first bite.
- Six opposed pistons spread clamping force across a wider pad area, which helps even out heat buildup and resist the fade that shows up on longer downhill runs.
- A larger 330mm rotor gives the system more thermal mass than the factory disc, so the same braking energy raises rotor temperature less over repeated stops.
