I have a 2.2L LS, and my car has rear drum brakes. Can the rear drum brakes be converted to disk brakes? Does the conversion package even exist?
Thank you

 

Yes it exists...But that's expensive...

 

yea its gonna cost you around 900 for the kit to do it and its gonna delete the rear abs and you'll have to run at least 17" wheels to clear the calibers since its a big brake kit.

 

And anyway, since most of the braking comes from the front, I don't see the point of getting discs for the rear..More esthetic than really efficient...And there's no ABS on LS I think...I don't have ABS on mine..

 

ahh yeah i didnt think about the ls models not havin rear abs.. but yeah unless your doin autocross or some type of road racin then you really dont need that much stoppin power.

 

Even then just getting some really good front brakes should be enough.

 

drum brakes are perfectly fine reallyh just upgrade the ffronts. it's just for looks a good set of slotted rotors and pads and good taken care of rear drums will stop just as well as all disks.. i'll be honest though i wish i had all 4 disks

 

SSBC, look on cobalt addiction or Turbo Tech Racing.

but like everyone else said, just upgrade the front brakes. I am about to invest $12,000 in my build and all I'm doing is slotted front rotors, HAWK HPS pads, Russell stainless steel brake lines and new shoes for the rear drums (drums have over 45,000 miles), I am getting 17 x 8 wheels with some good rubber, all of that in harmony should bring my car to a halt quickly. rubber on the road will substantially alter brake performance.

so if you dont already, get more rubber on the road and some minor mods to your brake system and you will be happy.

 

Yeah we have sold MANY SSBC drum to disc conversion kits for the cobalt, they are a great upgrade.

 

thanks guys. i'll just stick to upgrading the fronts, but i just don't like how the drums look... eh, the hell with it. i always wondered... which are better cross-drilled or slotted?

 

the upgrade kit is more for asthetics than anything... not gonna make that much of a difference. like said, its a larger kit, so to compensate, you would have to upgrade the fronts as well.

As far as the drums... paint them. I am gonna do mine black this spring. basically make them as invisible as possible. I thought for a while of painting them silver with a black section to look like a disk and caliper at high speeds, but decided against it.

your best bet is to get cross drilled and slotted. but make sure that the slots are straight, curves dont do anything, and make sure the slots reach the edges of the rotor, otherwise you are not efficiently dissapating heat. I just upgraded to the GMPP slotted and drilled and love them.

 

kevlar brake shoes and cross drilled drums, ftw

speed holes in the drums make you stop faster

 

this may be a silly question, but what does "FTW" stand for?

Painting the drums black doesn't sound like a bad idea!
How much were your GMPP rotors?

 

thanks... calipers and drums are going black this spring.

rotors were 160 from Crateenginedepot.com

BTW.... FTW means "for the win" another way of saying something is good.

 

Curious, are there rear drum upgrades for the 2.2s around?

Upgraded drums plus brembo front discs would be one sweet setup.

I painted my calipers and drums black a while ago. They look GREAT. I can get you a pic if you want.
