wheel question/fitment?

Hey everyone, just have a quick question concerning fitment of some new wheels/tires for my 2000 TA. I have the eibach pro kit which lowers 1in. rear and 1.25in front and have been looking into A.Z.A. staggard wheels. I want to get 18x8.5 front with 235/45/18 and 18x9.5 rear with 265/35/18. bolt pattern 5x120. I do not know the offset of the wheel but the wheelmax guy says they will fit. Please fill me in if anyone has this size wheel or know any definitive answers. I want to purchase soon!!! Thank you for any useful info. Also, I have 4 new toyo proxes FZ4 275/35/18, will these work all the way around?
