x tech good answer on two of the counts,,,,,, yes 4:88 and i switched to a synthetic 75/90 half way thru last years season and to add i lost traction on two runs witched caused the car to shake real bad ,,as far as set up these where a set of used gears that i set up and worked to get get the best gear pattern leaning towards the toe of ring gear ,if you look you can see that the drive on the ring gear runs the entire tooth ,i have no idea of time,passes on the set but they didnt have the fractures in the ring or razor sharp edge ,these are just pulled from my car , a g/sa 3650 lbs car tha ran 11:50 to 11:80 depending on air conditions with a 1.529 60 ft ,,i was on the fence about going with the synthetic low weight and it showed that there wasnt enough viscosity witch ended up with metal to metal on hard launch and the tire shake didnt help,,,just asking who runs a 8 3/4 with a heavy car how they are doing with there set up gmonde
