My 235/60r/15 inflated to the correct pressure at standing with the tire deflection turns out to be 24.75" When rolling it might grow a bit.
I can afford to lose a fair chunk off the line. The 3.73 now puts my first at a 14.02 ratio. Taking off is second right now is a 9.08 ratio and it handles it with ease.
The 3.08 will put my first at 11.58 I don't want to go any lower than the 3.08 as i don't want my highway rpm to drop too low
Currently in 5th what farting around i can bring the rpm down to 1100 in 5th and accelerate out of that quite nicely.
