I bought the car around 2 years ago and still trying to sort some of the mods out . I am not sure what the final drive is I thought it might be 3;73 but I am not so sure anymore . 1st and 2nd gear go by so fast dont really watch what the speed is when hitting 6000 rpm but in 3rd it hits redline at around a 100mph . I am thinkng maybe 4;10 gears know but could not find any RPM charts to help. Thanks for any help
