With 13" rims, you'll probably want the highest rear diff available, especially as a ZX9 has quite low overall gearing. Don't forget that highest geared = lowest number, so a 3.6 is higher geared (so higher top speed but slightly slower acceleration) than a 3.9, so I'd go for a 3.54 which is the highest you'll get for an Escort live axle.

Sting,

I'm assuming from the ratios your quoting that you're using a Sierra diff. I've done a bit of homework over the past few weeks on gearing as I too have a ZX9C2 engine, but I'm stuck with an Timken (English) diff in which 3.54 is the tallest ratio I can find. But ideally you & I ideally need a Sierra 3.14:1.

Drop me your email address and I'll send you copies of the graphs I've done, etc.

Regards
Adrian
