Thread: The Official what you need and how-to for CTS-V brakes

OK So an update as to my rear Cts-v project... the calipers are going to need a bracket in order to install them..they are off by about 1/2". The mounting bolts however are the correct size so that's a plus lol...I think the caliper needs to be spaces off the spindle about 1/4 of an inch as well. I will be designing a bracket soon and will CNC a prototype as well

sure... they look just like the fronts really, just smaller... as for the e-brake i wont be utilizing it... even if i were to do the rear gxp conversion i wouldn't use it either... i am going to start next week designing a bracket.. my roommate is an aerospace engineer so he will draw it up in AutoCad and then another buddy just bought a 5-axis CNC

Yup Brembo has a pretty generic design for these, these are the same off the '10 Camaro, G8 GXP, CTS-V, STS-V, Evo and I'm sure there are many others, sometimes the do change the bracket for mounting a little but I'm sure they all could take the same brake pads LOL.

On Amazon search for
ACDelco 172-2287 Caliper Assembly
ACDelco 172-2288 Caliper Assembly

Here are some pictures next to the stock brake calipers.

Just checked amazon and these are even cheaper now. $104 a piece

where did you see them for 104 each lol

he said on amazon.com

i know that lol i only found them for 126, which is still a smokin' deal anyways lol

Same part#'s? Lol... I found em around same $126-130 each. But not that cheap!

This is the first one, the picture is just wrong guys:

ACDelco 172-2287 Caliper Assembly : Amazon.com : Automotive

Second one is "Used" but repackaged and certified by amazon, good to me:

Amazon.com: Buying Choices: ACDelco 172-2288 Caliper Assembly

Be careful that it is the right part... may want to call Amazon to double check... because when I ordered the rear caliper... they sent me an e-brake pad. But the part number that was with the pad matched the rear caliper p/n... just a heads up for anyone ordering

Its the one buickman used. Caliper Assembly is in the title.

It was the title when I ordered it too.. also the picture was of the caliper... don't know what happened but it was a pain to return and get the correct thing.. just a heads up is all

looks like i'm putting brembos on my 2.5i.

I'm interested to see where this CTS-V rear brake project goes.

Left - 89047726
Right - 89047727

I found these as updated GM part #'s for the same CTS-V Calipers... Can anyone confirm this. Same price +\- $130...
just getting all my ducks in order

Well I made some good headway the other day, got some good measurements and mocked up bracket... next few weeks are busy at work so hopefully I will have some time in between

This is good news. If it all pans out would you be willing to manufacture a mounting solution? I would obviously pay you
