So, finding wheels for the Fiesta is difficult enough, finding light, Street class legal wheels is even harder. From what I can gather, Rota Slip Streams in 16x7 might be one of the lightest wheels available for the car at (depending on the source) 13.5-14.3lbs. The problem? The offset is ET40. I've yet to confirm this, but I've been told that the previous +/- .25in offset allowance has been changed to +/- 7mm. If this is the case, only half a mil needs to be taken off the mounting face to get them legal, although proper fitment with tires that run wide such as the 71r in 205/50/16 might demand even more offset, say a 2 mil reduction to ET42. Any thoughts on having a machine shop lightly modify the wheels? They're lighter than the expensive Oz's and IMO look much better.
