I did last months roadbook, last weekend. TOR managed it in the summer in a near standard Disco. Not now you can't. All three Discos in our group received panel damage on one section. It's also a section you can't avoid. We were not particularly bothered by it but if you took your shiney standard Disco along the track, you're in for a beating. Great fun though, I enjoy their roadbooks, and they are getting harder 8)
