Thanks to BM for 'putting the numbers' to the answer.
Mikie.....48 divided by 15 is 3.2 and is a 'quick leave off the line' or less effort coming out of the corners for a T/C and GT8 etc than the 16/47. The 'bigger' that ratio result is, the quicker your engine max rpm is reached.
Are you 'cutting your tires'....(foams).....? There is also a 'ratio tool' there that I've seen the 'pros' using in their personal bag of tricks.
