No the front is a true 5 lug conversion. 300zx hubs. I just dont have enough lug nuts for both wheels. haha. So yes, it is just to roll the car around on.
The rear adapters use one of the 4 lug studs as a safety. The other 4 studs of the 5 are coming from the adapter. Its a good design. Way better than the crap I had on the red car at one time.
No updates really. Saving money for the brakes, driveshaft, r200 diff and other stuff.
