Hi lads can any of you help I need to no if there are any cosworth diffs out there 2wd and 4x4 that are the same rashio,s or very close why I'm asking is I'm running a skyline gearbox in my focos and I can here the diffs working over time and I don't no how long they will take the strain there under see wot it is a 4x4 box works on about 70/30 split this is only a ball park figer and a skyline runs 50/50 split . So when I click the skyline box it to 4x4 they start to fight each uver in 2wd it's all good . I can put any cosworth diff in the car that I won't as I'v got a 7.1/2 rear beam fitter . It's just I'm not very good when it comes the crown wheel and pinions so any help would be fab . O I'v only got a small budget to sort this I'm not the Bank of England lol
Thanks for your help lads
