To the OP: sorry for the thread jack but I figured since you two are engineers I could use this as a place to bump ideas off you guys. If you want me to delete my posts I will.
No worries, I like the input and what you guys came up with.

bajallaman did you consider cressida rear rotors? ive been trying to find some that are vented, my plan was to use 300zx rear calipers because they are super super cheap in the junkyards. I'd use is300 ones if I found them cheap, what are you using for a bracket on the rears?
The cressida rotors are a slight bit smaller in diameter than the stock celica/camry stuff but are vented and fit the drum ebrake bits.
I never did cause I got the legacy rear rotors to fit perfect with very little machining. The parking brake works and they are a large vented rotor. You can most likely run the upgraded rear rotor from Brembo (If you look at the first page, another user stated the option available) and run the bolt on 205 rear caliper. That would probably be the cheapest route, however it is not confirmed this works.
Just keep in mind when you're doing this the unsprung weight you are introducing. The cars the brakes come off of all have aluminum uprights. We have heavy cast iron ones and adding a heavy rotor does not help at all. This is where a two piece rotor will shine, but cost you. Also keep in mind practicality. Those brakes look beautiful ALLenTRAC, but I feel they maybe slight overkill for most applications. If you are doing an event like REDLINE Time Attack or similar, I can see that as helpful, but most of those cars are full on race cars with fully dependent brake systems. Going anything larger than equivalent to an STi seems unpractical. Also these rotors are rotating mass. Larger rotors = larger inertia = slower acceleration. These are all things to consider and I have put a lot of thought into.
I will be sharing my calculations soon once I finish the excel sheet. You guys can use it to analyze your different setups and see what works best. For my combination I got a 171% improvement for the front with around a 70% front and 30% rear bias(Stock came out to 74% front and 26% rear). Thats assuming I can find a 2 piston caliper in the rear to fit. I am most likely just going to make a bracket to get the Legacy caliper to fit. I will be deleting the ABS pump and installing a Bias valve to adjust my proportion to get 4 wheel lockup.
