Great write up & patience on your part! Do you know how much brake bias the Supra has, front/rear? I was thinking only the front would require a larger caliper & rotor, if looking for more stopping power. The rear calipers seem oddly large when compared to the fronts. In my other cars the rears were so tiny compared to the fronts. Thanks MattI wanted to update with some additional thoughts and info on the BBK.
Signature Werks made a decent product here. The build quality is fine, not amazing, not bad. The lack of instructions is unacceptable for something this complicated. For perspective, see the below picture showing the rear left caliper mock up. This is an extremely complicated setup and not having instructions made it that much harder. They were also very difficult to communicate with, only responding on Instagram, and not very well.
The rear e-brake sits VERY close to the EDC module on my KW DDC's, and Id imagine that it would be the same if you were on stock EDC shocks. I ran the rear suspension through its whole range and it never touched, but it gets within 1mm.
The fronts were much easier, obviously as they are a simpler setup, however you must remove the front fender liner to access the brake line. Not crazy hard, just an extra step.
I have had a lot of issues bleeding. I did what I thought was a full bleed on Saturday after installing, then took it out to test drive it and had NO pedal feel at all, so I knew there was air in the lines. I did another bleed Sunday and got lots of air out. The pedal now feels 90% stock, with a little bit longer stoke until initial bite. I may have to take it to PSI or Eurotech to have them cycle the ABS. I did feel confident enough to bed them, and man, they took a LOT of hard stops to get hot. Super excited about finding their limits at the track.
I should probably take some notes down on everything I got from SW as well as my own pics I took and write up a quick how-to, if anyone would be interested.
