The screw thread platforms let you fine tune stance and geometry easily using the supplied polyamide adjusters.

How it drives

Expect a flatter, more composed chassis with improved turn in and high speed stability, without the crashiness of cheap kits. We have fitted ST X on multiple customer W207 coupes and run them ourselves. Feedback is consistently positive on ride quality, fit and finish, and fast B road confidence.
