XYZ Racing Street Advanced Coilovers — Lexus SC 300/400/430 2001-2010

The SC 430’s factory suspension was designed from the outset as a grand touring package – soft, compliant, and built for motorway miles rather than corner speed. For a car weighing around 1,800 kg with a 4.3-litre V8 sitting ahead of the front axle, that means body roll through faster sweepers, a nose that floats over undulations instead of tracking through them, and a rear that can feel vague when you lift off mid-corner. The XYZ Racing Street Advanced coilover replaces all of that with a monotube assembly you can actually tune to how you drive.

These Z40-generation Lexus SC cars are at an interesting point – old enough to have enthusiast cachet, usable enough to drive hard without guilt. The Street Advanced suits that balance directly: it covers spirited road use as its primary brief, with the adjustability to handle the occasional track day when you want to test the chassis properly.

What this coilover does for your 2001-2010 Lexus SC 300/400/430

The 720-way damping adjustment gives you a meaningful spread from one extreme to the other – soft enough to cope with poor British roads during the week, firm enough to reduce the SC 430’s characteristic front-end roll on a circuit approach. Ride height is set independently through the threaded collar, so a modest drop to correct the factory stance does not sacrifice suspension travel in the process. With the geometry tightened at both ends, the outside front tyre stops bearing the brunt of cornering forces that the stock setup would simply absorb through lean. Rear damping can be matched to the front to bring the axle into line without introducing snap oversteer under lift-throttle.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most developed road and track day coilover line, refined over a number of years by their in-house professional team and validated through race programmes across multiple international series. The 720-way single-knob damping adjustment varies compression and rebound together across a wide operating range, allowing adjustments at the side of the track without specialist tools. A threaded body sets ride height independently of spring preload – a more precise approach than a spacer-only kit and one that preserves the suspension geometry across a usable height range. The Street Advanced is not a circuit-only product; normal road use is explicitly the priority, and the bottom half of the damping range reflects that, remaining compliant enough for a daily driver while the upper settings give access to real stiffness when you need it.

Fitment for the Lexus SC 300/400/430 (2001-2010)

This kit is fitment-matched to the Lexus SC under chassis code LE13, covering the full 2001 to 2010 production span of the Z40-platform coupé. Confirm your model year before ordering – the earlier Z30-generation SC 300 and SC 400 (pre-2001) use different strut geometry and are not covered by this fitment.
