Yeah but the 4.30 is the higher ratio, so if you want the front end to pull you would need the 4.30 front and the 4.37 in the back otherwise you would be pushing the front and it would want to get the back end out on you.
I vistited wuth ZUK on it and he said the 4.30 front/4.37 rear was the way to go. He had 5.38 front and 5.29 rear, which is the other way around with the higher ratio to the rear and apparently it had a slight negative effect on handling.
Makes sense, it's tricky to sit and think about. Definitely post up your results!
