Need help keeping up with C6 Z06 & Porsche GT3 on Road Course

Man, you guys have got it going here. It is intriguing to me how you make 45 year old cars handle with the newest. There is much science involved in calculating how much force is involved in cornering, which, I am sure, is the major variable in road racing.

Using the physics calculation for centripital force:

Force centripital = mass x (velocity squared) / radius; it seems that, all else being equal, i.e. power and meat on the ground and CG, the differentiatior is weight (mass). Is this assumption correct?

I know there are variables in rolling weight, but does the assumption of the mass variability have merit in road racing? Various steering geometry constructs are better than others, but is reducing sprung and unsprung weight the major or minor concern in road racing?

If this is the case, would concentrating on weight (mass) reduction be a large contributor to handling?
