XYZ Racing Street Advanced Coilovers — Honda TL UA8-UA9 2009-2014

The fourth-generation Honda TL (UA8/UA9) is a heavier, more isolated thing than its Acura TSX cousin – a 3.5 or 3.7 V6 sitting ahead of the front axle, SH-AWD on the UA9, and a factory ride that prioritised silence over body control. The Street Advanced coilover for the 2009-2014 Honda TL UA8-UA9 is built to address exactly that: a road-biased setup that lets you tighten the chassis without turning the cabin into a kit-car experience.

This is XYZ Racing’s most widely-fitted platform – the one their development team has iterated on for years, refined through worldwide race programmes before being signed off for road and occasional track use. For a chassis as nose-heavy and softly-sprung as the UA8/UA9 TL, that breadth of testing matters.

What this coilover does for your 2009-2014 Honda TL UA8-UA9

Drop the front ride height a sensible amount and the TL’s slightly tall, slightly disconnected stance gives way to a flatter, more deliberate front-end response – useful on a car that was tuned to absorb rather than report. The 720-way damping range is the real story here: you can run it soft enough on the motorway that bridge expansion joints don’t crash through the rear bushings, then add several clicks of compression and rebound for a back-road run and feel the front end actually load up under turn-in. On the SH-AWD UA9, that improved front-axle communication is what unlocks the rear bias the system is meant to deliver. Spring rates and damper valving are matched to the TL’s kerb weight, so you avoid the harsh-fronts / wallowing-rears problem of generic universal kits.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s volume platform – the kit refined over multiple development cycles by their in-house engineering team and validated through race programmes worldwide before being detuned for road use. The headline number is 720 damping adjustment combinations, accessed via a single top-mounted knob that handles bump and rebound together, which is the right call for a road-first kit where the owner shouldn’t need to be a damper engineer to get a usable setup. Construction follows the same monotube architecture XYZ uses across the range, with height adjustment independent of preload so you can lower the car without losing useful spring travel – a common failing of budget kits on heavier four-doors like the TL. The brief is unambiguous: normal road use first, the occasional track day second, with the bandwidth to do both without rebuilding the car in between.

Fitment for the Honda TL (2009-2014)

This kit is specified for the UA8 and UA9 chassis codes covering the 2009-2014 model years – the front-wheel-drive 3.5 V6 (UA8) and the SH-AWD 3.7 V6 (UA9). Confirm your chassis code against the VIN plate before ordering; the SH-AWD car carries different rear geometry and the kit is matched accordingly.
