Cheers for all the comments guy.. I will keep it updated as more progress is made.

For the moment im going to be using my Quaife Gearbox, Quaife Front and Rear Diffs.

I plan to go with a PD gearbox in a few months time once mapped.

I think as long as i dont launch it to hard, they will be up to the job for now. And ive just fitted Group A Front drive shafts and re furbished my rear drive shafts.
