Ha ha, maybe 'relaxing' wasn't the right word! What I mean is that it is easier to get into a rhythm that would otherwise have been interrupted by jumps and bumps.
Personally I loved it but after all these years racing at the track I have made some good friends and they all hate TC's (they are referred to as 'boring' cars) so I would be on my own!! [

What touring car are you running? I now those things can get very expensive.
