Hello Chaps

Did a bit of a search but not really any joy so just wondering if there are any people in the know regarding what power the Capri 2.8 (LSD equiped) shafts can take ?

I see there are stronger items available from people like Quaife and a company called Fostek, anyone any experience of whats best to go for or have any further info that would be relevant ?

Needs to cope with around 450 bhp coupled to 265 sticky tyres and a lot of abuse. Any help advise would be appreciated
