EB 2 piston to GT 4 piston upgrade?

[CTX148]

For those of us with the EB 2 piston front caliper/rotor setups, does anyone know if the GT 4 piston calipers will bolt to our exisiting mounts?

Was thinking about doing a brake upgrade but really dont want to go through swapping knuckles for the 6 piston brembos. Thought the standard gt front brakes would be a good compromise, if they bolt up.

The rotors are a different size, as well as the back plate (splash shield)... but I think the knuckles are the same for all models.

Thanks, I was tracking the rotors and calipers being different but didnt catch the splash shields would be different.

Looking at Levittown Ford parts website the shields are a different p/n for EB's and GT's.

PR3Z-2K004/5-A (EB)
PR3Z-2K004/5-B (GT)

The knuckles themselves, the only thing I'm seeing differences wise are the non-Perf. Pack models vs the Perf. Pack model knuckes so that looks promising

Based on some posts from the 6g forum it seems like ppl did this swap in the past but I wasn't able to find a. ref. to a S650 EB to base GT brake swap as of yet. If anyone has any info. on it I'd appreciate it.
