You want a longer box, the standard 19:70 FD is too short as it is in a tuned car for acceleration as you spend too much time changing gear.
With a decent stage 2 first gear is so short your faster to 60 if you start in 2nd rather than 1st. If you are doing 1/4 mile from a standing start in a santa pod / motorway slip road senario you'll be wanting to change into 5th before the end of the quarter mile meaning 4 gearchanges at half a second each.
The only final drive longer is the 19:63 in the hdi eco and its not a straight fit, infact to my knowledge nobody has ever managed to fit it to a 306.
