can i use the ss five lug pattern and disc brakes for both the front and rear on my cobalt Ls

 

Sure, all you need to do is replace all 4 hubs and install a new rear trailing arm in you car. Unfortunatly thats about I'm guessing $1500 in parts alone. Plus the calibers, brakets, hoses, disks, and extra lug nuts. You can do it its just really expensive.

 

NOT worth it, you can find pleanty of aftermarket replacement wheels, and breaks for the LS that will be better than the stock SS stuff.
