I'd like to get one of Marlins third members complete with an ARB. Should I consider high pinion? I'm gonna go atl least with a v6 housing, high pinion is only $100 more. No mods are needed for high pinion, right? Also, would 4.88s be too low for a daily driver. I've got a 5 speed, runnin 225 75 15s right now but would like 31s. Are 4.88s too low ya think? I want decent RPMs at highway speed. Right now I'm around 3000 RPM in 5th gear goin 65-70 mph.
