Whats wrong with the stock wheels, and why should I consider aftermarket wheels?
The stock wheel on the 3rd Gen RX7 is in fact a very good wheel for a stocker, as it is fairly wide and is quite light (15.4 lbs each). However, there are three reasons to consider aftermarket wheels: 1) you want more performance, 2) you want better or more distinctive styling, and/or 3) you have money to burn. (I will keep my remarks focused on the 1st reason.) For best performance, I’ve uncovered two rules of thumb for matching up wheel and tire widths in the course of research: 1) the tire width and wheel width should be about the same, and 2) in no case should the wheel width be less than 70% of the tire width . Doing the numbers for a stock 3rd Gen RX7, 8 inch wheels are about 90% of the width of a 225mm tire, which conforms to both rules of thumb.
