oh, i wasnt aware that there were a host of people out there in japan working out VIP style cars to run hot laps at Kumakubo...../sarcasm
In any case, when i build my PJ car i will be conscious of those things.... but on a 5000 lb 4 door im not concerned with saving weight to gofaster and handlebetter around corners...
if that were the case... why did you buy an audi instead of built time attack civic that would run circles around your audi??? it would be faster and hadle better right? IN FACT, why not just start shaving pounds on the audi, remove the whole interior, cut away some interior metal, remove the airbags, spare tire, and a whole host of other things.... IT WILL BE FASTER, RIGHT?
Point proven? your welcome.
