What do you guys think of this steering/susp upgrade?

I like what you have planned except, I like to run the same size tires and wheels front and rear so I can rotate them on a regular basis. I think rear discs are a waste of money for most street cars. You might want to take a look at the Hellwig sway bars too. I haven't personally inspected the Firm Feel bars but I have the Hellwig ones and I do like the quality, geometry, and fit.
