I am building a Mk6 escort for track day use only. I would like to sacrifice some top end speed and maximise acceleration by changing the gearing.
I have been informed that in the IB5 range of gearboxes the gear ratios are all the same and it is the final drive ratio that is different.
Please could someone tell me what final drive ratios are available and in what model(s)there are generally fitted?
Also how do you indetify the final drive ratio of the gearbox?

Thanks
