only 63' straight.. is your FDR correct? i think the Transmission ratio number your looking for is 1.9
A local Xray t4 2015 driver told me the diff multiplier is 2.1, so I would definitely like a confirmed multiplier before I go nut changing gearing. Currently running a 17.5 Schuur Speed short stack motor but will be changing to a Certified Trinity D4 when we start our day racing schedule in early October.
I just confirmed that you are correct....and my local friend is NOT!!
