I know, but I've always been told that the caliper won't clear 16 inch rims. They say the Camaro ones are a tight fit as is.

I know this is kind of an old post but im wanting to do the gxp brake conv onthe rear of my car since them brakes suck on my car and i know you can use th estock callipers,pads and rotors but what about that bracket that the calliper bolts to to bolt it to the hub?? Do i use the alero one or the gxp one???

^^ Well do you have disc or drums currently.

A disc swap is straight forward. Take the old ones off, put the new ones on. If you have 16 inch wheels, no wheel change is necessary for Camaro/Impala fronts, GXP rear. The GXP, Corvette, XLR set-up require 17 inch wheels. No matter what, you need a 16 inch spare from a 00-05 Impala

The only issue I had with this swap was the rears had to be tapped into place with a hammer. Just tapped, not wacked in like your beating the shit out of somebody you hate more than anything, or Justin Bieber. Like I said earlier, the backing plate makes it a tight fit and after being on my car since 2011, the backing plate will still go back to it's old ways when I remove the bracket.

The only thing I find a challenge is pushing both pistons in at the same time with my C clamp. It can be done, thanks to a swivel head on the clamp.

I had to put the banjo bolts on the rear upside down to fit. No leaks. Just be sure to use the crush washers you get with the calipers and remove the old ones ;)

Call me silly, but IMO the OE 4 wheel discs stop great, and I can't imagine why anyone would feel the need to upgrade.

Not all N body cars came stock with 4-wheel disc brakes as many like my '99 GA has/had drum brakes on the rear. The front single piston calipers are also noisy and creak a lot when stopping. Upgrading to larger dual piston front calipers and rear disc brakes gives you much better stopping power without the creaky noise.....win-win. :coolio:

My front calipers always creaked.

Stock brakes did work fine on my car, but why not upgrade?

To jump on this debate... upgraded motor, upgraded suspension, upgraded size of wheels and tires... where now is the failing point of the car yet one if the most crucial??? The braking system... so it gets upgraded as well... bigger wheels and tires alone are reason enough to upgrade ... more rolling mass and larger centrifical forces will burn through stock brakes fast! I learned that the hard way... put on my chrome 20's and had to replace my pads after 300km... and i don't use my brakes much... i read traffic and let off and coast to avoid braking...

I was going thru brakes a little bit faster than normal. Car was running the the mid 14's and jamming on the brakes at the line to not break out. I'd need new brakes every 18,000 miles instead of 24,000 like I was getting

Not enough to get upset about, but still the dual piston set-up looks cool as well :awesome:

do any of you run ceramics with drilled & slotted rotors in the winter?

I have 4 wheel disc brakes...

Yeah my front brakes creak sometimes too..
my

Finally getting around to actually installing these and running into some issues...

I bought the camaro calipers used and just noticed they didn't come with the banjo bolts and the ones that came with the braided lines don't fit.... anyone know what the thread pitch is and a part number to get one at the dealer? Also it looks like the braided lines will rub on the axle which is worrying me a bit.... anyone else notice this?
Thanks for the help!

I am pretty sure its 10mm x 1.5 Maybe some one can chime in here
I am sure Matt had SS lines also

Does anyone have a list of the part numbers?

No need for part numbers really.

If doing the fbody swap.


04 impala rotors, 01 camaro pads and calipers. Simple.

what about the rear brakes?

Rear brakes you can only use 05 grand prix GXP brakes. They are expensive and not the easiest to come by because of such a scarce amount of GXP grand prixs out there.

I've read on the GAGT forum that the rear C5 Corvette brakes are very similar to the GXP brakes and will bolt on to the GA. That could be another avenue to try. I assume you'll need the bracket for them though.

Yes, that's true. I have run them for several years.
You use the GP GXP bracket and pads, but a Corvette caliper.
You will need to slightly enlarge the mounting holes on the Corvette caliper.

Hmmm interesting... but you can run full gxp brakes too right?
