Thanks for the replies guys. Yes, 30lbs is pretty heavy. Actually...they're 32lbs. A Q50 Sport Rim with Run flat is 62lbs. The tires (Dunlops) are 30lbs....so were looking at 32lbs per wheel.
My plan for the Q50S Hybrid:
Reduce Weight of Sport Rims by 9lbs each...by moving to sport wheel/370z front wheels. (36lbs total)
Reduce Tire Weight by 5lbs each, will switch from Dunlops to PS2 (20lbs total)
Install 2 piece Akebono rotors at all 4 corners. 10 pounds of each front wheel, 5 off each rear wheel. (30lbs total).
All said I should drop my unsprung weight by ~85lbs. That should net some NICE acceleration/braking improvements and probably nice fuel economy gains in the city. I have the hybrid and keeping it running in EV mode in the city really boots MPG's.
The Q50S Hybrid AWD is already a low low 5 second car to 60 (RWD is high 4's). This should net me a great improvement.
