XYZ Racing Circuit Master Coilovers — Honda TL UA8-UA9 2009-2014

The fourth-generation Acura TL UA8-UA9 was sold as a heavy, front-heavy luxury saloon with SH-AWD on the SH variant and a J-series V6 sitting well ahead of the front axle line – a layout that punishes soft factory damping the moment you start leaning on it. The Circuit Master coilover for the 2009-2014 Honda TL is built specifically to bring that mass under control on a circuit, where the standard car’s roll, dive and progressive understeer all show up within two corners.

This is XYZ Racing’s competition-tier damper – the same construction family used on their Racing Spec, Drift Spec and Tarmac Rally builds – dropped onto the UA8-UA9 platform so a heavy front-drive (or SH-AWD) Honda can be driven at the limit for a full session without the damping going off.

What this coilover does for your 2009-2014 Honda TL

On a TL with a 3.5 or 3.7 V6 sat ahead of the front wheels, the first thing you feel after fitting Circuit Masters is corner entry. Pitch under braking is held flat, so the front tyres keep their contact patch loaded where the factory car was already wallowing onto its bump stops. Mid-corner the body stays level and the front end stops washing wide the way a stock TL does once you carry real speed in.

The 9720 adjustment combinations from the three knobs – high-speed compression, low-speed compression, and rebound – let you split bump absorption over track kerbs from rebound control coming off them, which is the difference between a fast lap and a snappy one. Ride height is adjustable independently of spring preload, so you set the corner weights and stance without losing damper travel – critical on a car this heavy.

About the Circuit Master coilover

Circuit Master is XYZ Racing’s top competitive damper, sitting alongside their Racing Spec, Drift Spec and Tarmac Rally builds. It has been tested by XYZ racing teams worldwide and developed against repeated long-stint running at international circuits, which is where the three-knob layout earns its place – independent high-speed compression, low-speed compression and rebound, totalling 9720 possible combinations across the three.

The three-knob design uses small oil passages by design. When the car hits a sharp bump – kerbing, a deep expansion joint – oil is forced through the smaller orifice and you may hear a faint hydraulic noise. That is the damper working as intended for circuit duty and is documented behaviour, not a fault. The trade-off is the resolution of damping control you get back, which is what a sustained-pace circuit driver is paying for. This is not a road-biased coilover dressed up for the track; it is built for the track first.
