This looks nice.

895 for the front
1195 for the rear

nice. 2 grand to stop better. u palnning on buying these Z? if so let us know how they work.

Nah they are a little rich for my blood.

If anybody would have let me know a long time ago when I made that one post I was going to see if I could get a "group" discount( I work at SSBC) PM me.

Hey two questions one: Why are they only 2 piston in the front and 1 in the back, why wouldn't they make it 4 in the front and 2 in the back. And two do they work with the abs computer on the car b/c if they don't your braking will be worse. :)

nice find i bet there look good hoply someone is the ginny pig for these lol...

They do work with the ABS sensors, and as far as not using a 4 piston front and a 2 piston rear, I think it has to do with the size of the master cylinder. It can't make enough pressure to actually function with a bigger caliper size than those. I will ask tomorrow when I go to work and actually find out why. Also these calipers compared to the stock ones they are alot lighter. It's all about the unsprung weight.

I understand about the unsprung weight but the prce for such a benifit is way too high. I think they are reaching for the stars on the one. I would have to thing realy hard for 1000 for all 4 but 1000 for 2 that is out of the question. besides that I realy want them.

That's why if I could get a bunch of people togeather to order them all at once I might be able to get them discounted. I understand that almost $2000 for a 4 wheels is not chump change, but if you wanna play you gotta' pay :) I keep gnagging for my brake kit, so more than likely I'll be the guinea pig for the people on the forums except for the one guy. His car was used to develpe the kit.

big breakes are cool and all but you have to watch out for the significant powerloss at the wheels. 5% is not uncommon loss from the added weight the big breaks add.

I dont understand your reasoning behind that. The calipers dont move so weight isnt a concern there and the rotors used would not weigh much if any more that the solid stock ones.

"GOT BRAKES? We didn't think so! SSBC now offers the ultimate solution to the braking problems on GM's new Delta platform! Big stopping power in a little package."

Since when is their braking problems on the SS? Don't we have have the best brakes in our class? Don't get me wrong I love nice brake kits but I don't think this is too neccesary until you do some serious performance mods.

I think this will be more of an extreme visual upgrade, simply because our 18's make our rotors look small!

here's a great question. Have you ever taken your cobalt ss over 130? Well i may or may not have and let me tell you, stepping on the brakes at that speed is scary. If anyone has ever had a big brake kit on their car they know what i mean. The brake fade from 130 is absolutely insane and the bigger brakes don't fade as quickly. Convert to a big brake kit and tell me if you'd EVER go back to stock brakes ever again, there is no such thing as having too much brake power.

Uh stepping on the brakes in any car is going to be scary at that speed, aside from extreme performance cars. And the only reason why they're better at those speeds is because they're a hell of a lot lighter then the SS... and more aerodynamic too.

I dont understand your reasoning behind that. The calipers dont move so weight isnt a concern there and the rotors used would not weigh much if any more that the solid stock ones.

Unsprung weight always effects a car more than sprung weight. Anything not supported by the suspension has a larger performance effect the heavier it is than something sitting on the suspension. Though usually the weight difference for even a large big brake kit is nominal. Most popular kits use lightweight two piece rotors, and aluminum on the hats and calipers to keep weight down.

If anyone gets those let me know how they feel, I'm planning on getting them for my Cobalt.

I dont understand your reasoning behind that. The calipers dont move so weight isnt a concern there and the rotors used would not weigh much if any more that the solid stock ones.

the calipers dont cause the power loss, the greater mass of the larger rotors is multiplied by the increased diameter. if you take something that weighs the same, but with a greater diameter, it takes more energy to get it spinning or to stop it from spinning.
when you add both mass and diameter the effects get exponetional. the same thing happens with bigger wheels and tires. all else being equal, a wheel tire combo that places more of its mass at the outside will dyno less at the wheels.

how much bigger are these rotors than the stock ones? i know the stock ones are pretty big and for these it says 17" wheels are required for clearance. dont the ss/sc brakes require at least that?
