I would like to know if i can keep my stillen cai gen 3, stillen gr kit, magnaflow cat back exh, and 18" blizzaks and cobb ap and move them to my possible 2010 g37xs. I am in between leases and would like to know what i need to sell before i return my 08 back to stock to return to dealer.

 

Yeah don't think you can move them to the sedan...

What size are the tires? The xS with the 18s uses 225/50/18s I think?
