Thanks for the replies. Ill probably take it more local anyway as the track is miles away and not worth wrecking it for, but even at the closer track it can get 4-6 feet off the floor on grass which I would expect it to be a bit more durable on, especially when the upgrades get sent out.
Decisions, decisions.
I do like the fact corally listen to the customers though and fix the issues, even if it does take them ages
