The Ultimate Car Tuning guide is now on-line!

The Ultimate Car Tuning guide has now gone live and is available to download from the 3 major on-line book stores as listed below, so download your copy now!


Once downloaded you will receive free updates for life. The first update will be in about 3 months time and they have already have lots of companies to add to it including Santa Pod raceway and many more. They hope that over it’s first 12 months the guide will continue it’s growth and will evolve into a much more comprehensive package than it already is.

If you have any feedback or ideas about the guide then please do not hesitate to contact us, all ideas, criticisms and suggestions are greatly received, after all nobody knows the tuning scene better than you guys. We can pass on the details to the writers of the guide.

Here at GSM Performance we can be found in several areas of the guide. We have written an article on fitting after market seats into your vehicle. So once you have bought your seats from GSM Sport Seats we suggest reading this to ensure you fit them safely and securely. We have also got links and information to our GSM Brakes website and we will be writing more guides and articles for this publication as the guide grows.
