First off I gotta thank my buddy Sam (Ninjacoupe/Pony772 on the boards) He helped me out BIG time!
The install went fairly smooth except for a few snags along the way, but we all know it NEVER goes 100% right. We built the rear outside the car and then put it back in. I went with the 03 cobra 31 spline differential, FRPP 4.30 gears, moser 31 spline axles and all new bearings, races, shims and seals with Amsoil synthetic gear oil. I got it up and running on Thursday and all was well except for a slight hum on decel. We tightened up the pinion nut and that cured that problem.
As for the overall feel and streetablity, driving around town normally isn't much different than the 3.73. It definatly rev's much quicker when you get on it
The gears should give me another 3-5mph and let me use that last 1000 rpm's of powerband the 3.73's weren't letting me use.
