Yes, the rims are made by Fikse. The fronts are 17X8 and rears are 18X10. They were a little expensive, ok a lot, but the money spent was so worth it. I struggled with the purchase for months, as this was a lot of money for four shinny round rims. However the second they mounted them, I totally forgot about the $$$ (I still think about it from time to time. ha, ha) The set cost me around $3400 w/tax and shipping. I found a guy, after I placed my order of course, that would ship them to my door for around $3140. I had to eat the difference on this deal.
As for weight, the fronts came in around 17.75 lbs and the rear around 19.50 lbs each. The rims, along with the H&R springs, have totally and completely changed this car into a super exotic IMO. These rims give me more looks then I could have ever imagined.
Thanks for the compliment, it means a lot coming from fellow NSX'ers.
