You should consider going with a higher spring rate up front to balance it out. 900 rear is pretty high. It's possible and some race car's do run slightly north of that but your really going into some different territory there. Most track guys run somewhere around 400f/800r for this platform. I currently have it and I think it rides just fine on the street. I would probably bump up the front spring rate a bit to ~500 if I were to do it again and keep the rear the same.
Stiffer rear sway bar is entirely unnecessary especially once you get more power down to the ground and stiffen up the suspension. The back end will be coming out enough as it is without the help of a bigger sway bar.
