Totally agree with MWS comments on unsprung weight. I was disappointed that CF composites were not on the LCI. But the 516s are at least a small improvement.

It is very difficult to find aftermarket rims for the i8 that are lower weight than the stock rims.

Titanium lugs help a little bit, I got them and saved several ounces per wheel.

The i8 tire set-up is consistent with the difficult trade-offs between Eco and performance. Hence there is some room for performance enhancement at minor reduction in efficiency.
