Front and rear BBK for $2,000 is a lot more appealing and affordable than $3,500+.
I know you don't need the rear BBK for thermals, I'm more interested in a rear BBK for the lighter 2-piece rotors. I think the Wilwood 6R/4R kit designed for the twins is probably the way to go. That is the most affordable matching front/rear BBK setup and probably one of the lightest, too. Those WRX Wilwood Dynapro calipers are an amazing deal, it is too bad they don't have a rear we could use.

WW 6R/4R I don’t think the rear are lighter. And fronts barely lighter. But they will obviously hold up to tracking abuse way better.
Rears are tough to drop weight because of parking brake. A few rotor options that lose a little weight in rear but sacrifice parking brake.
For a more hard core track setup then a real front and rear BBK like WW or AP is great.
For a more casual setup the LW WW 4R + some slotted DBA rear rotors and pads is a solid cheaper setup.
