How low are 355 gears

Yup, it depends on what you want from your car. I used most of my cars as daily drivers and back and forth to work. 15 miles one way with half and half in town and highway but I still ran gears from 3.23 to 4.10's but I didn't run 14" tires either. Didn't know you could still buy them! May as well go with hi-way gears because the 14's won't do much for ya in traction anyways....if you want that 340 to shine, you need to put some tire behind it. They are good for easy high 13's in stock form but 14's most likely won't put the power to the ground.
