I would talk to Charles at Powertrix. He's a great guy, and their stuff is great. If your not going coilovers, I would get the Tein S Techs because of the tire/height you specified and the drop your looking for. They are about $165 approx. and drop the car aggressively. Heres a link to Z1 for their S Techs.[ http://www.z1motorsports.com/product_info.php?cPath=6_8&products_id=1236 ] That being said, I would go ahead and get the front and rear adjustable camber arms from Powertrix, because your going to need em down the road eventually.
