I just fitted an ST version with the end can to my GP, first bump I went over the tail can bracket unclipped the panel and if it wasn't for my cat like reflexes catching the panel it would have been down the road. It wasn't any big pot hole either, it was a small trench like thing. It happened about 2 miles into the first test!
Has anyone come up with a solution for this? I've not really looked yet but before I start just thought I'd ask.
