I wanted to know that if i got some 18" wheels would i have to get my studs extended? or can i just leave it at that??
Thanx scion family

 

you don't have to worry anout extended studs however depending on the offset of the wheel you might look into a set of One Ton Garages 10mm shims for the rear wheels. they go behind the hub so you don't have to worry about anything.

BTW, I ran 18" x 7.5" with a +45 offset and needed the OTG shims. I was ok in the front.
