XYZ Racing Street Advanced Coilovers — Honda TSX CL9 2004-2008

The CL9-generation Honda TSX arrived in the UK as a grey-import curiosity and stayed because the chassis is genuinely good – K24A2, double wishbones front and rear, a 60/40 weight split that rewards a driver who actually rotates the car on the brakes. What it doesn’t reward is the factory damper tune, which goes soft and unbothered after 100,000 miles and starts to feel like the whole car is moving in slow motion over a B-road.

The XYZ Racing Street Advanced coilover is the spec to fit when you want the CL9 to feel taut and modern again without giving up the long-distance comfort that made the TSX a sensible daily in the first place. It is built around 720 damping settings on a single knob, so one weekend of fettling gets you a setup that copes with school-run potholes on Monday and a Cadwell trackday on Saturday.

What this coilover does for your 2004-2008 Honda TSX CL9

Replacing the tired OEM struts with the Street Advanced kit transforms how the CL9 puts power down out of slow corners – the K24 doesn’t have to wait for the body to settle before the front tyres bite. Turn-in sharpens noticeably, and the secondary ride over expansion joints stops feeling like a rebound problem and starts feeling like a sports saloon. Height is adjustable independently of damping via separate spring perches, so you can drop the car for stance or keep it close to factory ride height for kerb clearance without compromising the damper’s working range. The 720-way damping range means you can run it soft enough that a passenger won’t notice on a motorway run, then firm it up by a dozen clicks before a B-road blast. Brake dive under heavy stops is reined in without making the car feel skittish over mid-corner bumps – a balance the standard CL9 setup never quite manages.

About the Street Advanced coilover

This is the longest-running product in the XYZ Racing range and the spec the company has refined over years of road and circuit development with their professional team. The damper has been tested across international race programmes before being signed off for series production, with the brief specifically targeting normal road use and occasional track-day duty rather than dedicated competition work. The 720 damping settings are delivered through a single combined bump-and-rebound adjuster on each corner, which keeps tuning approachable – you are not juggling two knobs trying to remember which way each was turned. Ride height and damping adjust independently, so dropping the car for the look it should have had from the showroom doesn’t cost you damper travel. XYZ position it as the most popular kit they sell, and on a chassis like the CL9 that genuinely splits its life between commuting and weekend driving, it is the obvious place to start.
