XYZ Racing Super Sport Coilovers — BYD SEAL 2023-2026

The BYD Seal arrives with a kerb weight north of 2,050kg, a low-slung battery pack acting as a structural floor, and the kind of instant torque delivery that exposes any softness in the OEM damping the moment you load the front axle into a roundabout. The XYZ Racing Super Sport is the kit for Seal owners who want the chassis to feel as deliberate as the powertrain – dialled down on body roll, raised or dropped to suit the wheel-and-tyre setup, but still civil enough for the school run.

This is a 36-way damping-adjustable coilover built for fast-road work with the headroom to handle weekend trackdays at Bedford or Donington. For a heavy EV saloon riding on relatively soft factory springs, that adjustment range is where the value sits – you set the damping for British B-road compressions one weekend, then firm it up for a sighting lap the next.

What this coilover does for your 2023-2026 BYD 海豹 SEAL

The Seal’s weight distribution is the headline problem the Super Sport is built to solve. With the battery acting as ballast under the cabin floor, vertical load transfer is brutal on standard dampers, and the OEM tune leans toward isolation rather than control. Drop in the Super Sport and the car stops floating over crested A-roads. Mid-corner bumps no longer push the nose wide; the rear settles faster on throttle pickup, which on a 530bhp Performance variant is the difference between confident exit and a traction-control intervention.

Ride-height adjustment lets you close the wheel-arch gap that all Seals leave the factory with, without resorting to lowering springs that ruin the damper match. Set the dampers soft for commuting and the kit rides closer to OEM than you’d expect from a coilover of this calibre. Wind them up two-thirds of the way and the chassis takes a set through fast direction changes that the standard car simply can’t.

About the Super Sport coilover

The Super Sport damper is engineered to eliminate the discomfort that comes from sharp bumps and rough surfaces – a real-world tuning brief rather than a track-only one. Construction centres on a height-adjustable monotube damper paired with 36-way bump-and-rebound adjustment on a single knob per corner, giving owners a wide working window between supple daily compliance and tied-down circuit response.

XYZ Racing positions this kit as the bridge between a daily coilover and a dedicated track setup. The 36 clicks span a genuinely usable range – early clicks soften enough for poorly maintained urban routes, while the firmer end of the scale holds the body flat through sustained cornering loads. Spring rates are matched to the Seal’s mass and front-rear balance, so the kit arrives set up for the chassis rather than as a generic shell you have to revalve. Suitable for both weekend race outings and daily driving, exactly as the brief intends.
