I wonder if any of these will work?

I think one needs to try it with the stock MC and give some feeback. On paper, increasing the caliper piston size without adjusting the MC bore size would translate to a longer stroke, and more sensitivity and a softer feel. The danger is actually running out of pedal stroke before achieving max braking performance (ie hitting the floorboard in a panic stop).
The Dodge hydroboost one looks like it would be close enough to at least possibly bolt up. Of course would need to adapt to the fittings. need to try it also

If that is true, then one needs to weigh the risks. Unbalanced F/R brake bias, or better balance with a pedal stroke that might be too long. If I had to choose, i'd go with the first one.
I am still waiting for someone to actually run this entire setup and report back. I actually backed out of buying an insert kit mainly due to the bias issue so if there is a way to actually fix it I may grab a kit despite my other concerns with the caliper modifications.
I moved my spacers to the front so I could get this thing off jackstands and take it for a spin. The amount the pedal moves before significant braking occurs seems to have increased. It reminds me of going from a manual system to a boosted system. The amount isn't huge (maybe 1/4-1/2" of travel) but it is noticeable if I'm not just being hyper sensitive. Braking performance seems increased and panic braking is still excellent. I was able to find room to do two panic stops from ~60mph and got the initial chirp followed by modulation that I'd expect. All in all, this is a great swap and the extra pedal travel will probably be no big deal once I get accustomed to it. I have the ATS Brembos in the front and the 43mm Taurus calipers in the rear. I think I'm going to need new front wheels though. The poke is a bit too much for me. Click the thumbnail for a larger image.

Why? Everyone is calculating cobra R like bias which is a ford build race car.
Like what omj posted?
Does he have the larger rear calipers? I didn't see where he stated that. Mustang5l5 is wondering about the ATS calipers with the larger 43mm rear.
Everyone running around with just ATS calipers up front has a bias of about 80/20 which is not acceptable. According to jack hidley of MM adding just the front calipers will actually increase the stopping distance of the car compared to the standard cobra setup.
He says it towards the bottom of his post.Does he have the larger rear calipers? I didn't see where he stated that. Mustang5l5 is wondering about the ATS calipers with the larger 43mm rear.
