I help run the TDOCuk forum (http://www.tdocuk.com/index.php) It's aimed at owners of diesel engined cars, both modified and standard.
We're trying to get a track days organised sometime in the coming months. We'd love to have loads of people to attend, so we're asking around different forums. We don't mind what you turn up with. The more the better.
Below is the link to the Track Day thread.
