I want to pass along to all who own either the new Malibu or the Epsilon model something of concern with putting on alloy rims or aftermarket rims. The studs in the front hubs will probably not be long enough to stick through aftermarket rims to allow you to thread on the lugnut more than three threads, this is very dangerous and can lead to possible loss of a rim and damage to your ride. There is a fix though, you can replace the studs with longer studs from the dealer, just go in and ask for stud for an 07 with aluminum rims, these studs are almost a half inch longer than the standard studs, which are pilot studs ( they don't have thread all the way to the end ), and have threads to the end of the stud. Here's a couple of pictures of my friend's 08 with 22's on it. We had to replace the front studs with the longer ones for enough thread for the lugnuts. Also to replace the studs on the 08's and up the hubs almost have to be removed from the spindle, just be careful not to break the wire for the ABS sensor that's a part of the hub.
