It lowers the car by approx. 40-60 mm at the front and 30-55 mm at the rear, which sharpens the steering, cuts body roll and closes up the wheel arch gap. The ride height is set on threaded struts, so you can go for a subtle drop or use the full approved range, and change it again later.\u003c\/p\u003e\n\u003cp\u003eThe ST XTA is ST's fast road and track day coilover. As well as stepless height adjustment and 16-click rebound damping, it comes with Unibal (spherical bearing) top mounts on the front axle, so you can adjust front camber after the coilovers are fitted to get more of the tyre on the road in corners and sharper turn-in. It uses a race spring system: a linear main spring for consistent, predictable behaviour, supported where needed by a helper spring that keeps the main spring seated at full droop. ST is part of the KW automotive group, and the kit is developed and made in Germany using KW engineering.\u003c\/p\u003e\n\u003cp\u003eST makes 3 versions of the XTA kit for the Audi A3 8V, split by drivetrain, front strut diameter and front axle weight. Between them they cover the 1.0 TFSI, 1.2 TFSI, 1.4 TFSI, 1.4 TSI, 1.5 TFSI, 1.6 TDI, 1.8 TFSI, 2.0 TDI and more. Use the table in the Fitment section to find the right one, then choose it from the drop-down.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront lowering:\u003c\/strong\u003e approx. 40-60 mm (varies by version)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear lowering:\u003c\/strong\u003e approx. 30-55 mm (varies by version)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight adjustment:\u003c\/strong\u003e Stepless, on threaded strut housings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum ride height (wheel hub centre to arch edge):\u003c\/strong\u003e front 325 mm, rear 320 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamping:\u003c\/strong\u003e Adjustable rebound, 16 clicks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSprings:\u003c\/strong\u003e Linear main springs with helper springs where needed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop mounts:\u003c\/strong\u003e Front Unibal mounts with camber adjustment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrut housings:\u003c\/strong\u003e Galvanised steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproval:\u003c\/strong\u003e Parts certificate (German §19.3)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eLowering figures are ST's, measured against the standard car.

Set the ride height within the approved range, tighten the suspension bolts with the car's weight on its wheels, and torque everything to the manufacturer's figures. A four-wheel alignment is required once the car is at its final ride height.
