I know this is lazy and i could probably look through the thread but i need a gearing start point for a 4.5R in a BD running rubber on carpet on a BIG track, talking two basketball court size but with some twisty bits. Should i go with the 10-10.5 suggested? ran 10.25 in practise as a shake down at smaller club and seemed ok. have seen setup sheets with 8.5fdr though
spose i could just wait and see if pushing the limit is a good idea!
