XYZ Racing Drag Racing Coilovers — Mercedes-Benz SLK R170 4/6 CYL 1996-2004

The Mercedes Benz SLK R170’s front-engine, rear-drive layout puts weight transfer squarely in the coilover’s hands the moment you leave the line. XYZ Racing’s Drag Racing coilover for the 1996-2004 SLK 4/6-cylinder cars is built around that single job: shifting mass onto the rear tyres fast enough to convert engine output into forward drive instead of wheelspin.

This isn’t a dual-purpose road-and-track spring-rate compromise. It’s a launch-focused set-up, tuned so the R170 chassis squats and loads the rear contact patch the instant power hits the rear wheels, rather than letting the nose-light roadster rock backward and spin up the axle on the line.

What this coilover does for your 1996-2004 Mercedes Benz SLK R170 4/6 CYL

Fitted to an SLK R170, this kit’s job is to control how quickly weight transfers rearward under acceleration. The adjustable set-up lets you increase preload and damping stiffness at the rear to load the tyres harder and sooner off the line, while the front end is set softer to encourage the nose to rise and shift mass backward instead of resisting it. That front-to-rear balance is what stops the rear tyres breaking traction and turning a launch into wheelspin instead of drive. On a road-registered R170 doing test-and-tune nights, it also means you can drop the car back to a usable ride height for the drive home without disturbing the settings that got you down the strip.

About the Drag Racing coilover

XYZ Racing built the Drag Racing coilover specifically for 0-400 metre standing-start runs, and the platform is engineered to work across FWD, RWD and 4WD applications rather than being tuned for one drivetrain layout. The core idea is weight management: independent front and rear adjustment lets you bias mass toward whichever axle is putting power down, so the driven tyres get pressed harder into the tarmac the instant you launch. That extra compression on the drive tyres cuts down the time they spend spinning free before they hook up, which is where a run is won or lost in the first fifty metres. The same set-up that helps the car leave cleanly also keeps it settled once it is up to speed, reducing the twitchiness a soft road set-up would show at three-figure speeds. On the rear-drive SLK, that translates into rear-biased settings that load the back axle hard on launch.

Fitment for the Mercedes Benz SLK R170 4/6 CYL (1996-2004)

This kit is specced for the R170-generation SLK built between 1996 and 2004, covering both four-cylinder and six-cylinder engine variants. Chassis code ME23 confirms the fitment on this listing – check your V5C or chassis plate against that code before ordering, as coilover mounting points differ across Mercedes generations.
