That was my hunch, I get the impression sports touring tyres have come a long way in the last decade or so. I've heard the Ron Haslam race school apparently use bridgestone T30 but have no proof.
You'll be fine mate. Just remember they tend to lose grip / get greasy as they get hot...If it's a very warm day and you're pushing on, ease off a bit from time to time. It's not the leaning that stresses the tyres, it's the stopping and going...
Cant be bothered to change them if they'll do the job, will most likely reconsider once they need replacing. I've had a rear tyre move sideways when driving out of a corner before, so just want to avoid that sphincter-tightening experience if possible. It's still fresh.
