Matches the Rockauto listing #2 above. Rockauto's price is a little better plus the 5% discount.

Rear rotor:

Matches the Rockauto listing #4 above. Rockauto's price is a little higher but probably about the same with 5% discount.

I should check GM Parts Direct also.

Yeah, you also have to use care when browsing the 2014 CTS because they were making both Gen 2 and Gen 3 cars that year.

Oh yeah, the CTS coupe (and V coupe).

See....annoying.

Not on Rockauto's list.

I am not liking the options shown for the rear. It seems to be missing the Vsport. The front listed three parts I think which would be CTS coupe, the V coupe and the Vsport. The rear only lists 2 and I think they are 2nd gen parts.

I think the Vsport rears are the same as the other CTS models. I wasn't planning to do the rears since I think all the pulsation is coming from the front. Is that bad?

The rears aren't brembo?

And no you don't need to do the rears but you should probably know what the inner and outer pad life is.

What's really confusing is I think the CTS-V used RPO J56. Well if Rockauto is accurate, J56 was also the RPO for the Vsport. That means the RPO application does no good for trying to identify gen 3 Vsport vs gen 2 V in 2014 and 2015.

The Vsport rotors on Rockauto cross to:

CADILLAC CT6 2016-2018
CADILLAC CTS 2014-2018
CHEVROLET CAMARO 2016-2018

This is believable.

The rear is CTS only.

The rears are not Brembo. Some people swap in the V rear calipers, but I don't plan to do that.

I will check the rear pads when I do the brake bleed (the fluid is nasty).

Check both inner and outer.

So the front calipers are fixed 4 piston units? And the rear are what? Regular floating calipers? Single or dual piston?

You may want to call (or visit) a local dealer to get a printout on brake part numbers. Tell them you are shopping around for brakes or something. Get the part numbers, specs and prices if possible.

Just ordered the OEM, non high performance pads on ebay for $90 + $8 shipping. Also picked up a set of rotors from a Texas GM dealer selling on eBay.
