They came with the car I just bought, and were unknown what model Enkei they were. I sent pics to Enkei and they said they were GF1's 18X8's and they weigh 18lbs. They come with tires I'll go check the brand in just a bit. The fronts have good tread left and the rears are almost new.
$500 Plus shipping. Just give me your state and zip and i can give you a quote, i have an account so it the shipping cost should be good.
UPDATE: Tires are: Fronts are Toyo Proxes FZ4 245/40ZR18 And the rears are Spector H100 245/40R18 93H.

Thanks for looking,
Mike
