I have been running the Spec R Diff in my T3 now for 2 meetings. One meeting indoor with 10.5 and the other outdoor at Cotswolds UK in modified (Lipo 4.5 SP Gt2.0 ESC)
The Car was crazy fast outdoor with a lot of power and the diff coped fine all day with no leaks and it was very consistent.
Laptime wise the car was very fast and competitve and I will be using the diff at round 2 of the BRCA Nationals at Cotswolds this weekend
