I would stay away from the Drag brand wheels, they are cheap and prone to structural issues (which is why they are so cheap). I have also seen a set of Voxx wheels that were on a vehicle for autocross that failed during a lap, lots of issue.
If you want cheaper side of wheels, atleast go with one of the wheels that American Muscle offers IMO. They have a lifetime structural warranty, and 1 yr finish warranty, so if there are any issues with structure, you're covered.
