XYZ Racing Super Sport Coilovers — BYD SEAL 4WD 2023-2026

The Seal 4WD’s underfloor battery pack sits low and central, giving BYD’s dual-motor saloon a genuinely low centre of gravity for its class – but that same pack adds mass the standard dampers were never calibrated to control. Add instant torque from both motors and load transfers to the outside tyre far faster under hard direction changes than in a comparable combustion saloon, which is exactly the kind of input that catches soft factory suspension out.

XYZ Racing’s Super Sport kit targets that gap directly: a car that’s quick enough to enjoy on a fast A-road and composed enough to take to a weekend track session without the ride turning punishing on the drive home. For a 2023-2026 Seal 4WD carrying real EV weight, that balance matters more than outright stiffness.

What this coilover does for your 2023-2026 Byd 海豹 SEAL 4WD

Fit this kit and the first thing you’ll notice is body control – the Seal 4WD stops wallowing over compressions and settles almost immediately after a bump rather than continuing to move through the next corner. The 36-way damping adjustment lets you soften the ride for the commute and firm it up for a trackday without swapping parts, which matters on a car this heavy where a single fixed rate is always a compromise somewhere. Independent ride height adjustment also brings the centre of gravity down further, sharpening turn-in response and reducing the nose-lift you’d otherwise feel when the front motor puts torque down out of slow corners. Together, the result is a chassis that reacts to inputs on this AWD platform instead of absorbing them a beat late.

About the Super Sport coilover

Super Sport is XYZ Racing’s answer to the discomfort that comes from running a car hard on UK roads – broken tarmac and speed bumps shouldn’t beat you up on the way to a circuit. The 36-way damping range means the same set of dampers can be set soft for daily use and stiffened for a weekend on track, rather than forcing an owner to pick one compromise setting and live with it. Ride height is independently adjustable front and rear, so stance and corner weighting can be set to suit the Seal 4WD’s specific weight distribution rather than a generic drop. It’s built as a dual-purpose kit rather than a dedicated race product, which is why it suits an EV saloon that still needs to cover motorway miles between track outings.

Fitment for the Byd 海豹 SEAL 4WD (2023-2026)

This kit is specified for the Byd 海豹 SEAL 4WD, chassis code BY09, covering the 2023-2026 model years. Check your build date and drivetrain variant against the configurator before ordering, as fitment is specific to the 4WD dual-motor version rather than the rear-wheel-drive Seal.
