As far as weighing them... I never really got around to it. But supposedly they weigh 14 lbs... which is nice. Although the weight of the Azenis compared to the Kumho 712's probably negated some of the weight savings.
I'm not really going for any particular look. I just wanted something that looked clean and not too flashy, which is why I'm trying to get some OEM/Mugen sides and rears... I just wanted functionality with a little bit of style. I'm starting to get pretty serious about autoxing... but I don't want to go to a 15" rim just for performance. I wanted to maintain the stock size to maintain a good compromise between style and performance.
16" tires are much cheaper than 17's or 18's... For right now, I'll be rolling on 16's. When/if I do get a set of 15's though for strictly track use, I'll probably roll on a set of 17's.
Sorry Pearl... no bright banana yellow paint, aggressive body kits, dual exhausts, or a (then) giant wing for me

Although I do give you props for the hard work you put into your car.
Sandiegan: I took the rear mudguards off today.
