Ideas for a 3.55 diff

[stevema]

Hi

I'm building a project Triumph Spitfire with the F20 engine & 6 speed gearbox from the S2000.

I can't use the spoon's diff as it's too low at 4.11 so looking for something around 3.55:1. It has to be able to take the 240 horses kicked out by the F20 and be available second hand in the UK.

Any ideas for donors?

Thanks
Steve

thank you very much guys, found this beauty already.. not cheap but being rebuilt it should save hassles once installed

A complete rear axle should run you £200 or so, that's with shafts and all.

For an LSD in good nick? thanks
