Thanks everybody!
They do make them in an 18" version, but this is all about performance. I have always wanted some lightweight 17's, and then upgrade the brakes. I think these weigh somewhere around 12-13lbs. This sale on eagle F1's for $88 a piece plus $100 cash card made me buy the wheels sooner than I expected. I am waiting to see what happens with the warmonger brake kit. I am hoping to get those or wilwoods if the warmonger kit takes too long.
