XYZ Racing Top Sport Coilovers — BYD DOLPHIN 2021-2026

The BYD Dolphin is one of the first affordable EVs that owners are actually modifying, and the e-Platform 3.0 chassis presents a specific problem: a 1,405kg kerb weight sitting on a short 2,700mm wheelbase, with the battery pack dropped low between the axles. That weight distribution rewards a coilover that controls body movement without punishing the low-speed compliance the standard car was tuned for. The XYZ Racing Top Sport coilover is built for exactly that brief on the BY04 hatch.

Top Sport sits in XYZ’s range as the occasional-track-day spec that survives the Monday commute. Spring rates run roughly 2kg/mm stiffer than street tune and damping is increased 30-50% over a comfort setting, calibrated to absorb broken Tarmac rather than skip across it.

What this coilover does for your 2021-2026 BYD Dolphin Hatchback

Drop the Dolphin onto a Top Sport setup and the first thing you notice is how the front axle stops floating over mid-corner bumps. The extra damping suppresses the high-frequency shimmy that low-rolling-resistance EV tyres tend to amplify, and traction through the front contact patch holds up under throttle in a way the OEM dampers can’t manage. Body roll tightens up without the ride collapsing into a single-rate jolt – important when the battery mass shifts laterally through quick direction changes. Adjustable ride height lets you set the stance to clear the Dolphin’s relatively shallow front lip without raising the centre of gravity any higher than needed. On track, the recovery rate after a kerb strike is the headline gain; on the road, it’s the way bigger expansion joints stop reverberating through the cabin.

About the Top Sport coilover

Top Sport is XYZ Racing’s circuit-and-street crossover specification, drawn directly from the company’s own race programme rather than badged-on marketing. The damping curve is set 30-50% firmer than a street coilover and pairs with springs roughly 2kg/mm above the standard road rate, the combination chosen to soak up impact loads from broken surfaces while suppressing the secondary shock that unsettles the body. The intent is traction-focused: keep the tyre on the ground through compression and rebound, then let the chassis recover quickly enough that the next bump doesn’t compound the last one. Construction is XYZ’s standard adjustable-height monotube with separate ride-height and damping control, so corner balance and rake can be set independently of stiffness. All damping calibrations are derived from XYZ’s Top Sport race-experience programme, which is why this spec carries the company’s aggressive-driving recommendation rather than the comfort-biased Super Sport.

Fitment for the BYD Dolphin (2021-2026)

This coilover is fitted to the BY04 chassis Dolphin, covering the 2021 through 2026 model years across the global e-Platform 3.0 hatchback variants. Confirm your chassis code matches BY04 before ordering – the kit is specific to the Dolphin’s strut layout and is not interchangeable with the Atto 3 or Seal platforms.
