I already have a Jag 10.5 fitted to mine but i am yet to drive it, so I was interested to know how it felt on the road. Rod has ran the same set up for years in his car without any issues except drive shafts breaking but that was with around 550lb/ft which I will be a good 75lb/ft behind at very best. Rod has a special set of shafts made and hasnt had a problem since, he did say mine should be more than up to the job as they are though.
The installation of my diff is quite a bit different from yours though, mine will be an out and out road car that will maybe see the odd trackday/ session.
I was wanting a bullet proof set up as well, and good handling set up. I am hoping I will have managed this with the diff, box [TKO600], beam, brake and suspension combo i have got.
