If you have the 14" wheels, then you have a 4-lug car. These are not optimal for Road Racing as they don't have the 'big brakes'.
I am assuming that the perceived advantage was in gearing. This would depend solely on the tracks you run. You could find yourself short on MPH in spots where you need it.
I would upgrade to the five lug set up if I was going to RR.
