The only issue that probably isn't a big deal but if you drag race and have sticky tires the higher numerically the rear end the weaker the ring gear is since it has more teeth. I knew this but had to find out the hard way in another car. Sticky drag slicks with a 4.86 rear end (stock is 4.12), drop the clutch and "clunk" two teeth cleanly removed from ring gear.
