I wouldn't take a car to the Ring unless it has been running happily for at least three months and done at least a trackday or two.
It's a fook of a long way to go and have a problem, it's a punishing trip, lots of miles and the Ring breaks even standard cars working well.
Each trip every year most 200's break in one way or another, so be prepared to have to fix them as part of the "fun"
