We are dealers for many manufacturers of Performance Upgrades, if you would like advice on selecting the best products for your vehicle or prices please contact us on 01442 601028 As we purchase these parts from the same Distributors as online stores our prices should be the same or very similar.

We can supply and fit any of these products in our workshop. We dont supply parts without fitting them.

Unlike online stores which mostly have no idea what works well on any particular make and model of car, we have the knowledge and expertise to be able to make product reccomendations and have direct access to the support teams at the Product Distributors who in turn have the support of the actual manufacturers of the products
