Thank you, I gave u some rep for that tranceformer. So ive increased my gearing by 1.5% or the tire? That is very minimal. To where the driver cant tell the difference. So if I install some 4.08 gears I should still benefit from ~10% acceleration increase correct? I was told it wouldnt make much of a difference once the tires were in place.
