XYZ Racing Top Sport Coilovers — BYD QIN PLUS 2025-2026

The Qin PLUS sits in an awkward spot for anyone who wants to drive it properly. It is a DM-i plug-in hybrid saloon carrying a heavy battery pack low in the floorpan, which gives the BY12 chassis a centre of gravity most petrol saloons would envy – but the factory dampers are tuned for comfort over a soft secondary ride, and the standard setup runs out of body control the moment you load the car into a fast B-road sweeper or string two corners together at pace.

The XYZ Racing Top Sport coilover for the 2025-2026 Byd 秦 QIN PLUS is built to fix exactly that. It is the right pick for an owner who treats the car as a daily but wants the option of an occasional track day or a serious driving weekend without the floppy, undamped feel of the OE suspension.

What this coilover does for your 2025-2026 Byd 秦 QIN PLUS

You get height adjustment to drop the car into a stance that suits the saloon’s profile without wrecking the geometry, and you get damping that runs roughly 30 to 50 percent firmer than a street kit – the level XYZ deploy on their Top Sport range to settle the body without going full race-car harsh. On the Qin PLUS that translates to a flatter cornering attitude, less dive under regen and friction braking, and a noticeably more planted rear axle when the hybrid powertrain dumps its torque off the line. Tyre contact patch improves over broken surfaces because the dampers actually control the spring rather than skipping over compressions, and traction off slow corners is the most obvious gain you will feel from the driver’s seat. The car still rides – this is not a coilover that punishes you on a motorway slog home from a circuit day.

About the Top Sport coilover

Top Sport is XYZ Racing’s bridge between their street-biased kits and their full circuit hardware. The damper construction and spring rates are lifted directly from their Top Sport racing programme, then tuned back slightly so the kit remains usable on the road. Spring rates sit roughly 2 kg/mm above a street setting, and the damping is calibrated to absorb sharp impacts over kerbs and broken tarmac instead of crashing through them. The brief XYZ work to is suppressing body shock across big bumps while keeping the tyres pressed into the road, which is why the Top Sport line is the one their own engineers reach for when a customer asks for track-day capability without dedicating the car to circuit use. It is suited to aggressive road driving and to occasional track sessions in the same weekend.

Fitment for the Byd 秦 QIN PLUS (2025-2026)

This kit is built specifically for the BY12 chassis Qin PLUS in 2025 and 2026 model years. Confirm your build year against the fitment range before configuring – the BY12 platform shares hardware across DM-i variants, but spring and damper specification is keyed to this exact application.
