matt036 Donating Members 280 Member For: 14y 10m 8d Gender: Male Posted 14/04/14 04:25 AM Share Posted 14/04/14 04:25 AM I was running a 275 40 17 MT's. I was hittin limiter rite on the line if not right after but not before so it might have 1 or 2 mph at best left in it with that setup but would need a bit more power to get it there. For time and I was runnin id say puts me bang on the power figure it made. Link to comment Share on other sites More sharing options...

Id say the ba's had the taller gears for the 5 speed manual but released the 6 speed with the same gears. They might have gone the shorter gears in the bfs being a 6 speed alowing for 6th as an added overdrive. Link to comment Share on other sites More sharing options...

It's possible that Matt's is a non-factory T56 with a 3.45 rear giving him a bit more top end in 4th gear.Were you using the same tyres, Gaz?
