On a related note, I had some chubby chick in a red FR-S tailgating me the other day. When given the opportunity, I downshifted, gave her the soot bath/meth flames treatment and literally left her in the dust like she was standing still. It was clear she went WOT too. It was also clear that there was a very significant power differential in our rides, my 450-550 lbs of extra weight notwithstanding.
Anyways, what are your power goals? 400, right? Can that reliably be achieved on stock block? I'm sure you'll be much quicker than she was. Being pretty lightweight, it doesn't take too much to make these things fast, and their chassis dynamics are legendary.
