Varrstoen 2.2.2 Question
 

If I were to purchase Varrstoen 2.2.2 in the following staggered sizes:
19x9.5+22
19x10.5 +12

I would have to buy a 5mm spacer for the front because I have the sport package, correct? Also, I have been getting mixed answers as to whether or not I would have to roll the rear fenders. What tire sizes should I buy to slap on these wheels? I have done research and cant find the exact answers I am looking for. I dont want to make a 1000+ dollar investment and have it not workout in my favor. If anyone has these wheels I would love for them to tell me how their experience with these wheels went. Thanks in advance.

I am at stock ride height and plan on lowering with swift springs sometime in the future. Will this also be okay?
