(C&P from another thread)
This design allows for caliper movement for C-clip axles when the axle shaft moves slightly in and out of the axle housing. The Porsche calipers are a fixed caliper design. When these fixed calipers are put on a c-clipped axle , the movement of the axle shaft going in and out ever so slightly will cause the rotor to push in the pistons of the fixed caliper. This is very predominant when coming out of a tight corner and then standing on the brakes to slow down. Which results in a long brake pedal.(C&P from another thread)

Got your PM. Yes that was me and my car. That picture is from about 2002. The company that makes the rear brake kit is called Movit. It s probably best to get the whole kit as the factory Park brake cannot be used with the Movit kit. Also take into account the rear brakes on a Fbody are a floating caliper design. .

Thanks for the reply. Does Movit still offer a kit that has the Porsche caliper?

In a straight line, this phenomena is nearly nonexistent.
Again, I don't intend to dampen the fun nor downgrade your effort, however I make no apologies for sharing the experience that even I was warned about from experienced race teams, club racers, speed shops, and other engineers as well as my own personal experience.

Do some effective research on pad knockback and you'll see how hard it is to deal with. Those mods will do little to prevent it. As a matter of fact, going to an axle with more unsprung mass increases the possiblity as well as the any increase in MOI if a rotor of increased mass is used. It's a serious tradeoff of switching from floating calipers to solid calipers on a solid rear axle. Even the most sophisticated IRS's still get it quite often, though not as bad as the Solid rear axles can. Stoptech and Brembo engineers warned me on several occasions about this, yet I ignored them and discovered what they were actually talking about.

You'll rid one significant factor, but there can still be plenty of knockback. It's not just down to the deflection of the axle (which c-clips do contribute to on cornering), but there will always be a significant amount of mass that can deflect when cornering which can cause pad knockback. Again, nothing is 100% deflection free.
Also, you'll be most likely running axles with more mass as well as the rotors that will attach to your brakes.
Even the stock floating calipers are knockback susceptible, but just not as much as what you're looking to do.
Another aspect that comes into play here is increased brake bias to the rear, which will shift the brake biasing right back to the rear defeating one significant benefit to an F-body "front-only" BBK. Having more pistons in the rear caliper may seem like an improvement, however your stock brake hydralic bias will be affected as well (though this is actually more dependent on total piston diameter for one side rather than just the number of pistons).
Again, not trying to discourage you, but there's no such thing as a free lunch and no one trick solution.

That's just the tip of the iceberg.
In general, there's no mod comes without compromise. It's just that the mod you're considering comes with lots of compromises.

Will this eliminate the long pedal travel that I have been reading about???
