Hi Dave,
I bit off a bit more than I could chew on Sat running 3 cars. Will be running in 540 for a bit as I loved thrashing the pants off my B4 but still not catching Jez.
Maybe next time.....
Anyway as for gearing,
B4: 28t Pinion 78t Spur = 7.243 final drive ratio
Jrx2: 25t Pinion 84t Spur = 7.324 final drive ratio
This seems a good balance of speed vs acceleration as I could clear the double jump like the mod class.
Cheers Brett
P.S. Can't go this weekend
