anything between a 47 - 54mm roll out
I have run a highest of 53.6 witha SP GT 2.0 and SP 17.5 with motor just over 60 deg/c
Start conservatively geared and keep gearing up till motor temps around 65 deg/c after 5 mins and you can gauge from lap times and performance feel.
Always nice to have a few cars to run against.
