Can I change the rear offsets from 30mm to 34mm (staggered set) without any problems?

 

You should be fine. What offsets are your stock wheels?

 

Thanks for your response. My stock wheels was with the "appearance pkg" that has 36mm offset on the front and 30mm on the rear. I'm picking up 34mm offset on the rear and hoping that there will not be any problems.

 

Check how much distance you've got between the spoke to the rear brake because the 34mm offset, lower than your stock,
will push the wheels inside more. Not sure if you like to go for that look but most like the wheels flush to the fender.
