Which Gear

[nugget68]

Im getting ready to swap in a WC T5 from a fox body, currently a C4. I am running 255 40 17 rear (25.05 inches) and 225 45 17 front (24.97 inches). What speedo gear do i need?

assuming it is an average C4 with 7 drive teeth for the speedo gear, you need a 17 tooth driven gear.
