[Carl H]

k guys im going from a 4.08 final as per std on the s14 chassis here stateside to a r33 gts-t automatic with a 4.36 final...hooray acceration.now the question is will i need a new speedo gear to compensate for the change in rear end or if i can calibrate my speedo for the change how can i do this?

you can have a shop do the recalibration, it's cheaper than getting the new speedo gear that's setup for specific gearing (also very tough to find).
