So basically drilling out for the difference in bolt size it will open up the spacing so they bolt up?Yes, Cadillac ATS brembos. They are dirt cheap...even new
I've been searching for a used pair. Missed a couple that sold on eBay for $100/pair. I'm running corvette calipers now but wouldn't mind the Brembos
My understanding is the Spindle needs to be redrilled as GM uses a 14mm bolt while the spindle is drilled for Fords 12mm bolts. Also the bolt spacing is 1mm or so narrower.
Eventually I'll get to it. I'll repaint the calipers in a more traditional brembo livery
$700 plus shipping but yes. I’m actually more concerned about home much it of a direct install they are. What if I want to go back to “stock” calipers. Are spindles that screwed upi saw the same post, isn't the guy asking $600 plus shipping? seems like a decent deal.

Not same guy. But same setup. Minus the “corvette “caliper. The post I saw didn’t say what they were from. Just said gm calipersFound the post.
Looks like he's welding the mounting flange and then redrilling for sn95 spindle mounting.
These are also the same ATS casting.
I got a set of them also and wanting to do the mod. Little hesitant on drilling out the spindles to be honest. Curious to see what you come up withOk, dug into this and got some parts.
Not a bolt on swap, as claimed incorrectly. The road racing forums are giving flak on this mod.
To get them to fit Cobra 13.1 rotors, you need to open up the spindle mounting holes to 14mm and slot them about 0.5mm towards each other. You also need to mill off about 0.075" off the mounting face of the mount ears.
Then you need to remove about 8mm of the pad material because the rotor diameter needs to be about 13.4" vs the smaller cobra rotors.
So...some work needs to be done.
I think there is a better way. The calipers have steel inserts so they will mount a variety of spindles. My thought it to machine up a new insert with a m12 threaded hole offset 0.5mm to match up to the SN95 spindle spacing
You can see in the bolt hole, that if you go to a smaller m12 bolt that th sn95 use, you do have room to offset them inward, and perhaps upward as well to sit the Caliper lower and cover the cobra rotor better
I also think there's a better rotor to use too. I refuse to slot my spindle or shave brake pads. Needs to be bolt on or nothing at all.
I bought that Caliper for $50, so I'm definitely curious about doing this swap "correctly"
I like the paperweight idea. Clean it, paint it and give it a useful new life.
With those now out how close is the mounting?
