Can you describe for us what was done? My understanding is that the ZCP option includes different shocks, springs, and wheels (as well as some remapping of EDC). Does your car have EDC? I am just wondering if this upgrade could be achieved for non EDC cars. Also, how much of the improvement you perceive could be attributable to the wider tires? Finally, can you give us an idea of the cost?

Thanks for the write up.

Cheers!
