Diff for racing?
Hi can anyone tell me which diff would be the best, on average for racing.
I have seen several for sale but don't really know which one to go for.
I am hoping to use 2000e box or Mexico.
thanks Rick

2000E box?! that's a bit naughty, the race comittee wont be happy if you turn up with one of them 
Idealy you want a set of rebuilt 3:9, 4:1 and 4:4 diffs, finding out which circuits to use them at is part of the fun - allegedly 
To be more helpfull the general rule is a 3:9 for an Escort box and a 4:1 for a Type 9 - old ones tend to have an effective life of about one to two
hours under racing conditions unless you are lucky btw............

Why no 2000e box when the regs say any standard box from Cortina 3/4/5
They don't all have alloy bellhousing if that was the problem.
Also I thought (though i'm often wrong) that a Mexico,Rs2000 and 2000e box were all the same.

Ahh, right, oops!! just re read the regs...... originaly there was one that said that you could use any of those gearboxes mentioned apart from the
2000E, non of us could ever work out why that regulation was there at the time (apart from the alloy bellhousing thing as the max weight was 600kg at
the beginning). Those ratios are used in a more modern box as well which was never banned so it must just have been a weight and cost thing - and as
cost no longer seems to be an issue

If only I had time to change diffs in between events. It's all I can do to keep the car on the road as it is and get to the events. And besides
trying to work out which diff to use where would take me 2 or 3 seasons, and I don't think I'll be in it that long unfortunately....
