I'm having a new gearbox made at the mo and have the option of changing 1st, 2nd and 5th gear ratios.

What do other cars use and find good?
I currently run a Renault un1 box
I think 1st and 2nd need to b longer cos they are over so quickly at 400+ bhp
so was thinking if they are longer it means I get a chance to use the gears, hit about 40 in 1st, 70 in 2nd, then STD 3rd and 4th for quick midrange and a longer 5th for motorway cruising/top speed
I prob wouldn't want any more than 160/170 in my car tho lol.

Also I'm getting a plated Salisbury diff made
what sort of ramp angles, clutch packs... Would b best for mainly road use and a little bit of track and 1/4m use?
Cheers
