XYZ Racing Street Advanced Coilovers — Chrysler 300C 2005-2010

The Chrysler 300C carries its mass high and soft from the factory, and on the LX platform that means a big rear-drive saloon that floats over crests and leans hard through a roundabout. The XYZ Racing Street Advanced coilover kit for the 2005-2010 300C tightens that body control without turning a near two-tonne cruiser into something punishing.

This is the adjustable-comfort end of the XYZ Racing range, aimed at owners who drive their 300C every day but want the stance and the composure the standard dampers never delivered. Ride height comes down over those slab-sided arches, and 720-way damping lets you set the firmness to match how you actually use the car.

What this coilover kit does for your 2005-2010 Chrysler 300C

Drop the ride height and the 300C’s tall, boxy profile finally sits the way the styling always implied it should, filling the wheel wells that look cavernous on standard springs. More to the point, the kit reins in the body roll and the nose-dive that the soft factory setup allows under braking, which matters when you are hauling down a heavy saloon from motorway speed. The 720-way damping adjustment means you can run a supple setting for a long A-road slog and firm things up when you want the front end to bite. With the HEMI’s weight sat over the nose, that extra control sharpens turn-in noticeably without making the cabin crash across expansion joints. The threaded bodies also let you correct the slightly raked factory stance many owners want gone.

About the Street Advanced coilover

The Street Advanced is the most established kit in the XYZ Racing range, refined over years of development by the company’s own engineering team and validated in international competition before reaching production. It is built to straddle two jobs at once: civilised daily road use and the occasional track day, which is exactly the brief most 300C owners are working to. The headline feature is the 720-way damping adjustment, a combined bump and rebound setting that spans comfort-biased cruising through to tied-down circuit response. Threaded bodies give independent ride-height adjustment, so you can set stance and corner balance separately from the damping. For a heavy rear-drive platform like the 300C, that pairing of height control and a wide damping window is what makes a single kit work for both school-run weeks and a weekend of lapping.
