Ok, I'm game.
Didn't google
1. Surface area difference. Think airplane wings. also, just a small tidbit ... if you drive at about 60mph you'll get the impression that you're feeling ... ..... err ... bouncing jello !!!
2. "broader fenders?" height or width? If height, I'm gonna agree with the left turn fact and add in that if the suspension is also higher on the same side, then probably stability in turns is added.
3. "30 psi" --- I forfeit this answer. I didn't want to cheat by going to google.
4. +1 pressurized (not much but enough) +1 coolant.
5. lolo, a bit more than zero ... once again google has the answer
Actually, I should just erase my answers and give you Henry Ford's answers. "hold on while I call my bean counters
" That was probably one of the most educated answers I have read!
