Anybody know the difference between weights between the stock rims and the Mille Miglies EV-S 17" Rims? What needs to be changed in the car if i get the 17"?

 

Nothing needs to be changed. A drop would be nice, but isn't mandatory.

Not sure on the weights, but what wheels do you have on there now?

Stock SE's (16), 97+GLE 15" Sawblades, GXE steelies

 

I've got stock 16's on the car now. i didnt know if anything needed to be changed in the engine or anything. I was told once that you had to change the computer or something because the bigger tires would affect the speedometer or something. That bogus?

 

Why would the tires be bigger?
Educate yourself by READING the STICKYS in this forum.

Cliffs---> If you get the correct size tire, it should be within spec re: to your stock overall diameter and wont change a thing.
