Has anyone done the Caddy ATS Brembo front brake upgrade?

[Rusty67]

Apparently there is a hardware kit that allows us to bolt on the ATS 4 piston fixed caliper to the front. S&S Engineering makes the kit. I read up on this on a few other forums. No one seems to have put this kit on a Mach 1. I'm wondering if anyone knows if this setup will clear the Mach 1 rim without mods/spacers?

Also, I'm wondering how the pedal feel will change. I'm not sure how much this will change pedal feel due to the total piston surface area being acted on. We might need to change to a bigger bore MC to maintain pedal feel/travel.

On top of that, I haven't looked into the surface area between the two pad to see how much of a difference it is. I am interested in this swap. The stock brakes on the Mach 1 are decent but I've been looking for a way to improve them without going to a larger rim for a LONG time because the stock rim is heavy enough and the 18" stock style rim is, I think, even heavier.

It isn't a race car but I'd like the upgrade to be a win in every way instead of a concession in some ways and a win in others.
