No issues with the 18x9 rims with the 30 offset. I bought 245/35/18's for the front rims and they rub a little when turned sharply on the bump in the upper front of the wheel well. I am lowered though. At stock height it should be fine. I rubbed that same place with the stock rims and tires after lowering so unless you hammer it in a little, it's most likely going to rub when you lower the car. If you order Forgestar's you need to tell them if you want the metal centering ring or plastic one. For track use and to withstand the heat metal is best, for a comfy ride the plastic is best. You need the lugs and socket from somewhere so I just got them from Forgestar. Normal sockets won't fit in the Forgestar lug hole. I put 18x10's on the back but I think 11's will fit if the offset is right. Anything you want to know, just ask and if I have the answer I'll give it to you.
