Have done 1.50 in it, can definitely do 1.49.5, probably less in more skilled hands. I welcome any experts out there to make suggestions on how to improve it.
Here's mine. Good for 1.45.XXX with softs (maybe 1.44 with more practice) and I could maintain 1.46.xx with the hards during the race. The 5th gear is made for slipstreaming action.
The setup was made for racing and not hotlapping, so stability was the 1st concern.
