Vauxhall Corsa VXR Race Preparation


By John Thorne, Team Principal – Thorney Motorsport – Fri, 11 Nov 2011 13:00

In 2008, Thorney Motorsport’s Corsa VXR registered fastest laps at all race events, 6 overall race wins, and placed 2nd in the overall championship.

Here at Thorney Motorsport we have an excellent relationship with Vauxhall, as we are the only tuning company with Approved Vauxhall Repair status, we’ve been fortunate enough to produce an Corsa VXR race car, supplied by Vauxhall, for the purposes of testing and development. This has allowed us to develop a range of tuning products for the car and enhance these to the level of race preparation.


Building a race car is a very lengthy proccess, costing a lot of time, money and effort, however the more of this we spend on the car the better quality of racing we provide. We have a lot of experience with Vauxhall’s doing a lot of research and development on them. In ordered to get our race cars to winning standard the following things need to be addressed.

  • Reduce weight. The Corsa VXR weighs 1225Kg in standard trim, and can lose a huge amount of weight from its chassis. Depending on race series regulations lose all the peripheral toys and get it down to a bare chassis.
  • Brakes. Standard brakes are poor and certainly not up to track spec let alone race so replace with AP Racing 6 pot fronts and 4 pot rears with larger grooved disks.
  • Suspension. Replace for a complete Nitron coil over kit front and rear. The rear suspension towers will need re-inforcement.
  • Safety. Full 8 point cages are now available from Safety Devices and bolt straight in.
  • Power. FullThorney Motorsport Race exhausts (bore dependant on what turbo charger you run), turbo changes, delete the AMM etc etc, the list is endless but there are a lot of things you can ignore as we know they don’t work. Our race VXT has the same basic engine (older version with a few changes but its basically the same) and we run over 280 bhp from that so power is not an issue.

Our race cars have thier own unique colour scheme of black and green. These colours are printed on everything we produce. Below is the process we go through to give our Corsa VXR race car our black and green colour scheme.

We start off with a basic Corsa VXR and completely strip it out to its bare shell, removing everything little uneeded extra weight. Truth be told, the lighter the car is the quicker the car is. Once the car is stripped out all of the race interior can be applied.
