I have more in an Excel sheet when I get home I'll post.
Also my personal input. 15's are gear'd more towards a Track wheel due to it's Lighter Weight, Smaller Overall diameter tires, And the smaller tires weight less which inter is less Rotational & Un-Sprung weight. 16's look more of a show type wheel as it's a little bigger and "Fills" out the fender more.
15" Benefits:
- Light Weight (Reduced Rotational & Un-Sprung Weight)
- Smaller Tires
- Lower FD Simulation when using Smaller than OEM Diameter size Tires
