Summer Improvements

[scutter]

I would try the following for your questions,

1, Try blanking off the areas around the radiator to nosecone, air will always take the least path of resistance.

2, Has the diff got the correct type of oil in it? Would a service/oil chnage help?

3, Can't comment on aftermarket, did the ford have a built in limiter?

4, Cheapest option is to service what you have, mind Wilwoods always get good reviews. I've wilwood on the front of my v6 but standard 4x4 on the rear with mintex pads, can't comment on performance as not running yet.
