Brembo mounting bolt spacing

Brembo mounting bolt spacing
Hello all,
I am looking at picking up a set of brembos from a 03-05 suprcharged jag, 4 piston front and rear.
Anyone know, or can measure for me the spacing between the two mounting bolts for the front and rears?
These are not going onto a jag, but an old audi of mine.
Thanks!

Front Brembos are 150mm with 14.1mm through mounting holes.
Rears Brembos are 90mm, with threaded mounting holes most likely m8 threads.
Remember that the calipers are matched to the STR rotors. The way they are designed, you will have to stick with the STR rotor diameter and widths.
The rear rotors are a solid rotor about 1/2" thick

uhh... do you want rough measurements? you're going to have to machine something very specific to your application to make it work, so the measurements we provide here are going to be of little consequence for you,
you really need to buy the calipers and have them in hand first in order to start mocking them up for your particular application and then build hardware using measuerments garnered from that,
you will need to source appropriate rotors, or custom rotors or 2 piece rotors: hat and friction ring,
on top of that you will need to add an additional set of spot calipers to act as your parking brake, as the rear STR calipers do not have a mechanical e-brake provision,
although the cost of entry for a set of STR brembo's is pretty low second hand, you'll spend a considerable amount more trying to get them to fit your application,
does your 'old audi' really not have an aftermarket big brake kit to consider? I don't think you're going to save much money if any going this route,

I am in the process of acquiring a set of brembo calipers off of a jag
I already have a set of boxster caliper sitting around, but as my car weighs in close to 3800 pounds, they wont be enough for what I am looking for.
Yes, kits do exist, using usually porsche calipers, and then you purchase an adapter, and then depending on what vehicle you have, you purchase a set of rotors form either another audi, mercedes, or go the two piece rotor method.
I was just curious as to the ballpark measurements.

GS42R and TIjoe,
Thanks again for the info.
My understanding is stock these used a 355x32, and a 326x20 Rotor.
The fronts are 38 or 40, and 44 mm pistons.
What size are the rears?
what would you like to know?
Its a 91 V8, with a 5 speed. The original 3.6 v8 has been swapped for a 4.2l out of a 93 v8.
Ran ok when I got it, but not 100 percent.
Did the timing belt, and afterwards did a compression test and was not happy with what the numbers looked like on one of the cylinders.
maybe it was a stuck valve.
Heads have been rebuilt, seals changed, and valves hand lapped. Engine guy said everything was perfect and within spec.
I ripped the short block apart, had the block soda blasted, and spend a month collecting all the bearings for it, and bolts. Ended up with arp mains and the last set of connecting rod bolts on the shelves in america, supposedly.
Had my engine guy put the new rings, deves, in, bolt the con rods to the crank, and the crank in.
Putting on the front and rear plate, oil pans, heads, and timing belt, oil retention valve, valley pan, I did myself.
Pics, I have not made the brackets, going to start measurements today or tomorrow.
Pics of test fitting
making sure enough rotor for the pad to sit on
