In my 05 I went with the .373's. I had an issue soon after getting the gears installed last October where I broke loose in third on an interstate and did a 360. That being said, throttle has to be given a bit more respect, especially with the run flats and the .373's. I originally was going with the .355's but changed my mind last minute. I'm happy with the choice. You cant go wrong with the .355's or .373's. They both have their ups and downs. I think the .373's make the car much more user friendly in town and navigating through a parking lot. I hated riding my clutch to keep the car going 5 mph through a lot or over a speed bumps.
