Since these rim are 3 pieces, heard you can replace the lips and get them bigger so I was just wondering where can I buy these lips but a bigger size? is 4.5 the max on 17s? Only found 1 guy that was selling a pair.

 

You would need to get them re-barreled. Always loved the guys who did it with a step lip. Few guys have had success with Services

 

You might want to inquire with the guys at vrwheels or memoryfab.
