Gates thermostats £55

Relocation alloy expansion tanks £80

Designed for track cars to re-site the expansion tank to a more suitable position behind the front wheels. This in turn gives better weight distribution and (as part of other similar mods) frees up space behind the rad to let it work more effectively. Tested on our track car and proven to work. Comes with extra pipework, easy to fit, but won’t work with air-con still fitted. Why would you want air-con on a track car anyhow?! Sorry for crap pics.

Uprated water pump £80 bigger impeller shifts more water and quicker.
