Gary (a local guy) without a computer....got a set of Sumo 6.1's installed....he has 27 inch tires on his Zuk....with stock diffs

he told me he paced it with his GPS and at 4,000 rpm's his speedometer said 70mph and his GPS said he was doing 67mph in 5th gear high range.

how does that compare with a GRSII? (in high range)
Ron Conley got a set installed last night too...he has stock diffs and 33 inch tires...he'll be giving us a report as soon as he exchanges his Sumo 6.1 for his GRSII

where did you find that excell file?
nevermind I found it

the T case gearing is before the spedometer. So it doesnt matter what t case gears you run it wont affect the spedometer.

way old thread.
