So I have Enkei GF1's on my car, 17x7 with 205/40/17 khumo tires. My question is, how much do these wheels weigh? I've looked for hours on the internet trying to find the weight of them, and for some reason can't. They aren't on wheelweights.com, or not at least that I can find. I was wondering if maybe one of you could find it for me, or know where it may be. The reason I'm asking is because since I've put them on I've gotten worse gas milage and my car seems to accelerate slower. Oh and does anyone know they weight of the stock steel rims that come on an 04 es? Thinking about getting new ones...
