Road comfort you can feel

If your standard suspension feels crashy or unsettled on rough tarmac, this kit delivers the sweet spot. The car glides over broken surfaces with far less sharpness yet remains controlled in corners. With 16 precise clicks of rebound, you can set a cushier ride for town and motorway use or add firmness for a more connected feel on your favourite roads.

Installation and setup

Professional fitting and a four-wheel alignment are strongly recommended. For expert installation, choose MJ Modifications in Warwickshire - request a fitting quote at info@mjmodifications.co.uk.
