I have a 2004 Sedan 5 speed, it is eating rear tires, after some discussion at a different shop (new tires and alignment at large chain that is big out here 9 mo ago) it appears I need a camber kit. So while I am at it I was thinking about a few upgrades, the car will be a daily driver about 60 miles a day of mainly highway with a few fun corners thrown in. I am thinking about the SVT suspension kit, which camber kit would be best ? and is there a better way to go or what wlse would be good to replace while I am taking it apart anyway. Car has 139,000 miles. I have read the stickys and threads, I need help please.

Tell them you want the toe set to 0 that will fix your problem. I bet they are giving you alignments that are "within spec" but still bad enough that they will eat your tires. I highly doubt its all camber wear unless there is excessive rear camber(more than 1 or 2 degrees)
