A quick question on different rear gears
If I put a set of 3.9 gears in my 6spd... will I have to get the speedo reset? Or do the wheel speed sensors tell the speedo how fast you are going and therefor don't have to touch a thing. I just absolutely need this answer so I can finally say weather I want them or not.
