Byd SEAL 05 2025-2026 — Coilovers

The BYD Seal 05 carries its DM-i hybrid battery low in the floor, and that changes the suspension brief entirely. The centre of gravity sits low, but kerb weight climbs hard, and the soft factory tune lets the body lean and pitch the moment you start pushing a heavy plug-in saloon. The XYZ Racing coilover range for the 2025-2026 BYD Seal 05 swaps that compliant compromise for ride height and damping you set yourself.

Six spec levels cover the spread, from the fast-road Super Sport to the circuit-focused Circuit Master, so the kit matches how you actually use the car instead of a single factory setting. Every option is a full coilover – ride height, corner balance and damper feel all adjustable on the car.

What these coilovers do for your 2025-2026 BYD Seal 05

Drop the Seal 05 onto its new springs and the first thing you feel is body control. Lowering the ride height tucks the wheels into the arches and kills the tall, soft stance the standard car runs, while adjustable damping firms up the rebound that lets a battery-laden PHEV float over crests and wallow through long bends. Set the height to suit your roads and the nose stops diving under braking, which matters when you are hauling down nearly two tonnes of hybrid. Corner-balancing the platform evens out the mass the battery adds, so turn-in sharpens and the car answers your hands rather than its own inertia. Daily usability stays intact too: soften the damping for the commute, then wind it up for a B-road blast or a track session.

About the XYZ Racing coilover range

XYZ Racing build these as full coilovers, not a lowering spring bolted to a factory damper. Each unit pairs a height-adjustable spring platform with a tunable damper, so stance and feel are set independently. The range splits into six tunes for the BYD Seal 05. Super Sport is the fast-road setting, firmer than standard yet liveable. Top Sport stiffens things for keener track-day pace. Racing Spec steps up to harder rates and tighter control for circuit use. Tarmac Rally is made for broken surfaces and stage-style abuse, Drift Spec brings the steering angle and rear bias a sliding car wants, and Circuit Master sits at the top for sustained lap work. Spring rates and valving climb as you move through the range, so you buy the tune that fits your use rather than over-springing a road car.
