Tuning
By Thorney Motorsport
Welcome to the tuning section of Thorney Motorsport, here you will find detailed descriptions and explanations on the tuning upgrades we offer to BMW, Vauxhall and now Ford RS models. Each car is broken into sections covering Handling, Power, Brakes and more. Each section then has links to our shop where most upgrades can be purchased as mail order for DIY fitting.
We specialise in the road car tuning of all Vauxhall and BMW cars but we hold specific expertise in the a select few models.
- BMW M-Division Range - especially the E46 M3 & M3 CSL.
- We run the CSL Cup, catering for all BMW M3 Models.
- BMW E92 M3
- BMW E60 M5
- BMW Diesel Tuning
With our Vauxhall range we specialise in the VXR models, we own our own Corsa, Astra and Insignia vehicles which we utilise for all of our development work. We also use our Race cars as proving grounds for nearly all of the modifications we retail - we do not sell anything we do not believe in or test. As a direct result of our Dunlop SportMaxx success we developed the VXR-R and VXR-S models.
As part of our expansion we now hold a network of 50+ Official Performance Centres across the UK. These are Vauxhall Dealerships that have been specifically trained and vetted by TMS to offer our upgrades to the entire range of Vauxhall vehicles. An updated list of our Official Performance Centres is available here.
As befits our status as the only Vauxhall tuner with Vauxhall Approved Repairer status our Warranty terms are jointly operated with Vauxhall themselves under identical terms as your standard Vauxhall cover. This means that whatever the problem with your car, standard or TMS modified - you are covered at any Vauxhall Dealership.
We offer a range of servicing for BMW and Vauxhall, all covered by the manufacturers warranty using genuine manufacturer parts and equipment.
Our latest development in the Ford Focus RS. We have recently developed a range of tuning upgrades for the RS, entailing Power, Brakes, Handling and Race Car Preparation.
As well as our extensive road car tuning operation we offer a race car preparation and management service. As well as running our own race operation we offer race car build and management for owners running in the CSL Cup, Dunlop SportMaxx, Britcar, GT Cup, and British GT Championships.
