damn it i just got my car back today from my gear install and let me tell you 4.30's are the way to go. They are f in awesome. I used to barely be able to grab a 2nd gear squal now i can burn threw 2nd into 3rd and chip the tires in 4th. It livened my car up something great. I highly reccomend motives 4.30's and they dont whine and arent bad at all to install my mechanic said. I only needed one shim and that was the factory shim that was already in place.
