Is It Possible to Install Cobalt SS Turbo Front Brembo Brakes on the Cobalt LT 2.2

Hey everyone, I saw a few threads of people wanting to do conversions from stock Cobalt LT/LS and even SS/NA or Supercharged brakes to the Brembo Front calipers the Cobalt SS Turbos have. I think my cobalt has crappy braking to begin with and thought it might be a possibility to switch over to the brembos with the right equipment.

Basically if anyone has done this or knows of it can you please tell me from the stock brakes if I need new lines, a hub spacer, and if it would be possible to keep the 4 lug nuts as opposed to switching to the standard 5. I just got new rims and tires that are 4 bolt only so I wouldn't do the conversion to have to change my rims out again.

Just looking to improve braking in the front mainly and thought new bigger calipers would do the trick if they work with my car.

Thanks - TIMMAE!

It's possible to do the switch, you would need the lines and spacers and brackets and what not. You would also need longer wheel studs. As far as keeping 4 lug, you could but you would have to have some rotors drilled for the bolt pattern

With that said, unless you track your car it really probably wouldn't be worth it. A good set of pads and rotors is all you need. Never had any issues with the stock brakes

Not sure the 15'' would clear the Brembos unless you move everything from the SS suspension front and rear Including the proportioning valve.

Thanks guys for the help and info on this. I have had a impala SS for a few years that I recently sold two years ago and from going now to just driving my cobalt all the time the braking I feel needs a upgrade. I know especially on the highways the braking just isn't where I'd like it to be to be safe when going 70 + and a smart car cuts you off only doing 40 lol not cool.


I will have to think about how much this would cost and if it really would be worth it.

Thanks - Tim

I do believe the minimum you can run with the Brembos would be 17s. A friend of mine has a set of Saab 9-3 wheels on his SS/TC right now, and that is a tiiiight fitment.

That would be great if mine would be able to fit. They are Konig 17x7 4x100 Offset 40 millimeters Backspace 5.57 inches Bore Diameter 73.1 millimeters.

I wouldn't mind putting a spacer on them to fit inline with the caliper and rotor.

The stock 18s are a +42, so you have a couple mm extra there for brake clearance, but since it is a smaller wheel, you'll still have to test fit them (with redrilled rotors) to ensure they do clear the calipers.

Sounds like a plan hopefully in the next month or so I can see about getting them and what the all around costs would be.

Thanks everyone for your help ! I really appreciate it and glad I asked on here first

Just to confirm, these are the Saab 9-3 wheels my buddy is running with his snow tires on his SS/TC



They are a 17x7.5" wheel, +41mm offset. Obviously, spoke design does play a part, but 17s with that amount of positive offset (or ideally, less) should clear.

I really do wish I could find a brake rotor that has a 4x100 pattern that would be close-enough (or identical) to the 5-lug rotor used with the Brembos. Would make for a much cheaper swap for myself to retain 4-lug.
