you just posted track thoughts. (archive)

so i think this weight issue would be important to you. did you not just post what mods you would do in the future for tracking your car?
now, in my simpleton mind, force is always proportional to mass times acceleration. similarly, the coefficient of friction is also a function of how much force (which is a function of mass and weight). if you had the same wheelbase and the same tire width, you could carry more speed without losing traction in a lighter car.

this is the principle behind the lotus elise. you could call that a crappy jap car, too. but in an experienced driver's hands, it will probably put our M coupes to shame.

now, you also mentioned this bit about the more powerful cars all weighing 3100 pounds. that's true. the 360 modena weight about 3018 pounds. give or take. and it has much less torque and less hp than the new z8. but it does have a 550 pound weight advantage. so, do you want to guess which is the faster car? straightline? in the curves? on the 'ring?

as an enthusiast, i'm surprised that you care less about weight. it impacts brake longevity. it impacts suspension life. it impacts treadlife. these are all things you also mentioned in your: mods i would do after i did some tracktime....
