thanks for the timing!
I don't think I got any completely clear laps in that last session, but I wasn't losing too much time getting past people.
I have a bit of work to get under 1:10s still, but with a properly working diff, same length control arms left and right, and a bit more tweaking I think it can be done
I didn't even get the brakes up to temp (probably something about GTR brakes on a 1000kg car )
