Enkei RPF1 15x7 vs 949 6UL 15x8 for track??
Posted: Mon Oct 03, 2011 8:34 pm
I have a 96 Miata, dedicated track car used for HPDE and potentially NASA/SCCA TT. I use 205/50x15 G-force R1 tires and will be staying with that size.
My delimma: Enkei RPF1 15x7 wheels weighing only 9.8lbs or 949 6UL 15x8 weighing 12.3lbs.
The 15x8 will stretch out my 205 tires giving me added contact patch and stiffer sidewall. But I'm sacrificing unsprung weight compared to the lighter Enkeis.
It's hard to know whether the added power due to less unsprung weight is a bigger benefit or the added grip. I tend to think handling wins over hp, but when you've only got about 120hp at the wheels, maybe not.
Thoughts? Let's assume price isn't a factor.
