Further to earlier posts on tools, I found this kit at a tool show, at about £70 it wasn't the cheapest kit around but I felt that it was good quality and bits are available separately. It is made by Wera Tools. Funnily enough, the only time it's been used in anger was using one of the bits to adjust the rear suspension on a Bonnie. Let's hope that remains the case.
The tyre pressure gauge was not included.
