Considering a staggered set up for your WK2?
Please don't. For one you'll piss off Schleprock to no end and two if the Jeep would perform better with a staggered set up I think the crew at SRT might have realized the fact. I'm not saying stick to the 295/45/20 size but whatever you choose keep them the same. That is all.
