So I had been thinking of my brake solutions, and while I will likely not be doing my brakes till spring its nice to plan ahead.
Some noticed I was trying to sell my 205 calipers, but its seems harder than planned. I was looking at a st of stoptechs from a 7th gen celica. I had stumbled across some information when researching my 205 setup that lead me to think I could easily use this. I was reading the 7th gen forums and the 6th gen forums looking at hints for new rotor options since their dimensions were close. Well its closer than I expected.
These threads show that 185 brakes fit the st 6th gen, and the 7th gens fit them as well with a little adjustment. So therefore they should fit the 185 pretty easily.

As some know I am really busy trying to launch my new business and career this year and that is the priority. I still want to finish my car, but if I can do it simpler and with less fabrication I will. I am likely not doing as much to the car this year just due to my own time.
My other quick option was to use the revolution brake route or even the porsche caliper route. I would have likely gone wiht revolution just cause it leaves me the flexibility to convert to 5x114 hubs if I wanted to. The porsche caliper idea could work with the supra rotors but it needs to be offset by 3mm and lower by around 1.5mm, though it would make due without changing the height.
Most likely I am going to be using the 205 calipers just because that is what I have.
Part of this choice is using my rav4 spindle or my 185 spindle.
With no bracket I can run 12" rotors on the 185 spindle and 334mm rotors on the rav4 spindle. The hangup on the rav4 spindle is it seems I need a shallow setup to keep from hitting the ball joint. I need to take some more measurements before I decide, but I have a few other factors weigh out.
Over the past couple of years I have collected dimensions from a range of rotors I might use for my project.
