XYZ Racing Street Advanced Coilovers — Chrysler 300C 4WD 2005-2010

The Chrysler 300C 4WD carries real mass, well over 1.8 tonnes of AWD saloon built on the Mercedes-derived LX platform, and that weight announces itself the moment you brake hard into a roundabout or load the front axle through a quick direction change. Factory dampers on this generation were tuned for motorway cruising, not for holding that mass in check when the road gets interesting. The XYZ Racing Street Advanced coilover kit for the 300C 4WD replaces that soft factory tune with a monotube setup built around 720 damping settings, giving the driver a way to firm the chassis up without turning a comfortable car into a harsh one.

Street Advanced sits in XYZ Racing’s range as the enthusiast street kit, built for owners who drive their 300C daily and want it sharper on a spirited back-road run or the occasional track day without living with a stiff ride the rest of the week. Height and damping are both adjustable, so the AWD 300C can be dropped and tuned to suit UK B-roads rather than left at a fixed factory compromise.

What this coilover kit does for your 2005-2010 Chrysler 300C 4WD

Fitting this kit to a 2005-2010 300C 4WD tightens up the body control the factory setup gives away in favour of comfort. The 720-way damping adjustment lets you wind in more low-speed compression to check the nose-dive that comes with a V8 and AWD hardware sitting over the front axle, then back it off again for the motorway commute. Monotube construction sheds heat faster than the twin-tube dampers this car left the factory with, which matters when the AWD driveline is already adding unsprung weight for the dampers to control. Ride height adjusts independently of damping, so you can drop the stance without running out of usable spring travel on UK road surfaces, and the rear end stays settled under the torque this platform sends through all four wheels instead of squatting and stepping wide out of a junction.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s best-selling coilover line, refined over years of development by the brand’s in-house engineering team and proven across race programmes worldwide before any of that knowledge reaches a road car. The line is built specifically to bridge daily road use and the occasional track day, rather than specialising narrowly in one or the other. Each damper offers 720 individual damping positions, a wide enough spread that a 300C running commuter duty most of the week can still be wound up for a track session without swapping hardware. The construction favours consistency across a session, so damping force does not fall away as the dampers heat up. For an owner who wants real control over how the car turns in and settles rather than a fixed factory compromise, Street Advanced is the kit XYZ Racing points most 300C owners towards first.

Fitment for the Chrysler 300C 4WD (2005-2010)

This kit is built specifically for the Chrysler 300C 4WD across the 2005-2010 model years, matching the AWD-specific mounting points and geometry rather than a generic rear-drive 300C kit. Confirm your 300C is the 4WD variant before ordering, since the AWD hardware changes the front subframe and driveshaft clearances the coilover has to work around.
