they are continental extreme contacts. ultra quite, i had them on my gallardo spyder once.
the wheels are slightly heavier than stock i assume because they are cast wheel versus factory wheels are most likely forged. (correct me if i am wrong).
by far with this wheel choice, i am extremely happy with the fitment and its quality and price.
Niche is one of only companies in US that makes their wheels in house, not from China.
I have heard rumors of many other famous name brand wheel companies (i.e ADV.1) use Niche to make their wheels. its perfect for my daily vehicle!
Niche is made in USA? Thanks for the info. That's good news. I will inquire with a dealer re: the net weight of each, they look quite similar to the Avant Garde 510 wheel I've been stalking. You notice any difference in your MPG, if in fact wheels are heavier?
