Flush 20" on FX37

[airhunt2]

Hey guys, picked up a 2013 RWD FX37 and am planning to lower it with BC Coilovers and other necessary suspension parts. Looking to sit flush with about a 3.5"-4" drop in total, not looking to go air ride. Websites out there seem to offer some puzzling information as to what wheel size/dimensions I'd need to go with. I have the OEM 20's on there now but want something better looking. I realize the OEM size is a 20x8 with +50 offset, can I go with a 20x9 or 20x9.5 with +35 offset? I'm sure someone in here has theirs, any info, pictures, recommendations, would be greatly appreciated! Look forward to seeing some cool options!
