I don't think you will find much of a performance improvement with 3.08 gears. I originally put 3.55's in my '93 5 speed and it virtually eliminated the use of first gear and, was too high reving on the highway (nice take-off accelleration though). Then I changed to 3.27's and it was much much better all round. I'd buy the oem type Ford Motorsport gear set (about $200) rather than Richmond, because you will find them quieter. Also, when you install it or have it installed make sure you replace the clutch pack (about $50) for the traction-lock/limited slip. The actual gears I bought were made by DTS from Detroit, who are one of the suppliers to Motorsport.
