The electrical system on a competition car is responsible for more than just starting the engine. Modern day race and rally cars rely on their electrical systems to keep the engine running correctly and provide important information for the driver amongst other duties. So, it is important to ensure that your electrical system is up to the job.

The best place to start is the battery itself. We have a great range of motorsport proven batteries that, not only provide all the necessary power for your vehicle, are also capable of dealing with the vibrations and shocks that can occur during competition. We also stock other key electrical distribution components such as alternators and starter motors to get your engine running.

Along with a great selection of other electrical items such as lighting, camera systems and AIM Motorsport lap timers, this is also the place where you will find our great selection of gauges and driver information systems. Gauges are a vital instrument in motorsport applications and allow crucial engine information to be relayed back to the driver.

For everything electrical on your car, we have your needs covered here at Demon Tweeks with electrical parts and gauges from LMA Smiths, WOSP, Stack and Auto Marine.
