wow guys, i bought these calipers off ebay and just realized that they are not the same as everyone elses! the guy listed them as CTS-v calipers but he did not know the year... does anyone know what these are???





please help, i already bought EVERYTHING and HAD THESE STRIPPED AND REPOWDERCOATED ALREADY

 

Sorry to hear man....why don't you re list them and hope for the best. I've always felt it's iffy buying stuff online period....ebay or forums, you always take a risk!

 

yeah my problem is that i dont know what these are off of! does anybody know????

 

so i looked up this part number on the pad 07.7783.43

looks like its a rear caliper

anyone know if these will fit my rear brakes??

 

That's a question a lot of people have asked, but since it seems nobody's had rear calipers to play with, nobody's bothered trying.

I say, that since you have the rear calipers in your hand, do some measurements, and see if they fit the rear without modification. I'm sure everyone on this forum that's wondered about the V rear brakes would appreciate it.

 

maybe it's fate....watch them fit in the back!!!!

good luck again!

 

YES! Please try to fit these on the back. We have wondered if they fit for some time now.

 

yes, ill definitely see if I can fab something up. i can even machine a bracket if needed... ill let you guys know the results sometime this week i should get them back from the powdercoater tomorrow!

 

I think those are the rears on the newer CTS-V. That would be cool if they work. I have been watching this upgrade and like the front but would want rears to match. The fronts on the newer V's that go with these rears are actually 6 piston calipers. The older CTS-V's only had 4 piston fronts.

 

send them to this guy so we can all have a set of rears

yep, I already talked to him If I cant figure out how to do it, they'll show up on his doorstep

 

Thank you sir, I appreciate it

 

Any updates?

 

he made another thread, found it last week....doesn't fit

 

chance of making brackets ?

 

well the bracket would need to be so big that you would almost need a 19 inch wheel in the rear, even if you COULD do a bracket. the bolt spacing is different and the offset is VERY different. someone might be able to make something but it definitely wouldnt be worth the price :/ and probably wouldnt function very well

 

That would be highly probable. Unless one can modify other areas of the whole brake system with regards to proper effective piston surface area, modifying the rear brakes can actually worsen braking from what a stock system does. The 4th-Gen F-body brake system already comes heavily rear brake biased from the factory.

EDIT: One more thing I'd like to mention is that "bigger brakes" will certainly add more unsprung weight to an already unsprung weight laden rear suspension.
