Low ratio 25% reduction gears vvt auto gearbox qu

your right.
so i do 3100 rpm at 100 kmh,
so a reduction of 25%
3100 x 125% = 3850 rpm at 100kmh
thats assuming the overdrive doesnt lower it further.

the main thing i was getting at is with the power being a constant, was that i believe now with the bigger tires, the overdrive is dropping the revs so low in the torque band, that as you stated, she doesnt have enough power.
so lower the gears, it will raise the revs back into a usable torque range.



i got onto a supplier, and here was there response, as im orfdering them tonight, time will tell if it will work.

Hello,
with your 215/75/15 tyres and our 25% reduction gears you would be
a little lower than with stock tyres and stock gears combo, but
with the auto transmission I think this wouldn't be an issue in the
on-road drive and it would definitely be a huge improvement in off-
road.
