Denver I hope you flushed your entire brake system. That's some nasty lookin brake fluid you have in that bowl.

which w-bodies came with 12" rotors from the factory?

None that I know of.

Monte Carlo's have 12" brakes from the factory

If it were me though, I would go with F-body brakes.

why the f body brakes? i would think the monte's would be easier...but i dont know much about the brake systems yet....

Monte Carlos had 12" brakes.
You can use the Monte Carlo brackets with your factory calipers to install 12" rotors.
If you want to upgrade to F-body standards you will need brackets and calipers from an f-body with the appropriate pads. With those parts, and a tiny bit of fabrication you can buy the 12" rotors that are made to fit the Monte Carlo, or aftermarket rotors that fit your application and have dual piston aluminum calipers that are superior to the GP calipers.

Dementeddj, glad to hear that you're interested in our rotors. Did you end up purchasing them?

i didnt know D/S rotors made THAT much of a difference =X my brakes are squeeking...id say thats what im gonna go with

Iirc R1 is the vendor I got mine from.

herc how much they charge?

Most of the really nasty stuff in the bowl was from the junkyard F-body calipers I got. After seeing the color of the fluid, I decided against rebuilding them myself and traded them in for remans.

But I did a complete flush anyway, till I got brand new clean fluid out from each wheel.

Here's some reasons I like the F-body brakes more:

Bigger pads:


Dual piston calipers:


Combined with the 12" rotors, it stops much better than stock. And the f-body calipers weigh a lot less than the stock calipers, which offsets some of the weight of the 12" rotor.

All four I wanna say was under $150. I picked them up on Ebay for a buy it now price. I don't remember cause I ordered all kinds of stuff that day.

The weight claim is misleading though. Your rotor weight is what is important with stopping. The more rotating mass you have on an axle (bigger/heavier rims, bigger/heavier rotors, etc), the longer it takes to stop.

Heavier calipers won't effect your stopping distance, just your speed.

I'm sure the larger pads and stuff outweigh the heavier rotors...but the the weight savings on the calipers won't help you stop quicker.

so whats so great about 12" rotors?
