Yes, I ran 20mm spacers for a while on my X, and they looked awesome! However, I recommend extreme caution, and input from professionals, because I had a lot of issues and ended up taking them off.
- It changes the camber of the vehicle, which lead to destroying my rear tires in just a few months
- I had trouble getting the nuts to torque properly, and there are clearance issues with some wheels, since your stuck with the factory studs.
- Because Tesla uses studs in stead of bolts, you're taking a risk mounting spacers because it's not as strong, puts more tension on the wheel bearings, and as you know, these cars generate a tremendous amount of torque. It could void your warranty.
Good luck!
