Is J60 a non-vented rotor? I don't think its really worth doing this, and this comes from someone who converted the front to brembos. You have to pull the hub/wheel bearing to get the backing plates off, otherwise you can trim/cut them. Is this just for looks of are you trying to solve a problem?

 

J60 is a solid rear package but I have vented rotors on the rear when I bought it a few years back. It’s odd because I have the 18” wheel package that came on the car so you’d think I would have the bigger rotor package on it but it’s not. I was wanting to do it because I need new front calipers anyway and I like the looks of the Brembos. Figured if I’m going to replace the calipers and rotors I might as well get what I want. I was actually going to buy the larger J61 dust shields from rock auto if I get the bigger brakes. I believe the dust shields are 349mm. I’m trying to find my best route either with the Buick Regal setup or the Camaro SS setup. I like the look of the red calipers on the Camaro and the black with Chevrolet racing on it. But if I can find a bargain on anything Brembo I’m content. I was wanting to put EBC dimpled and slotted rotors on the calipers.

 

Thanks for all your help man. I really appreciate it. So these don’t come with the brackets right? So I’ll have to get the bracket along with the mounting hardware right? They just come with the pad hardware is what I gathered. Also do you think I’ll need wheel spacers? I have the factory 18s on my limited ltz.

 

Brembo is the bracket. Its a fixed caliper, bolts right to the knuckle. They have pistons on both sides of the rotor so it does not need a bracket and sliding pins, you'll also probably want to get a piston compression tool specific for them so you can change the pads when it comes time. Use your original 18mm bolts, you will need the calipers, pads, and either buy the regal GS dust shield or trim the curved edge off of yours. I tried trimming first and didn't like it so I got the Regal ones, also changed the wheel bearings with high quality Timkens since they have to be pulled to get the shield on and off.

For pads, be careful to find some without the roller skates on top if you're not going to use a 19-inch wheel. They are just little vibration dampers that are attached to the top of the pad, some people (like me) just cut them off with a Dremel, it has no real effect unless you're tracking the car.

Your OEM wheels will definitely not fit, you'd need at least a 25mm bolt on spacer. Generally speaking, most 18s won't clear the Brembos no matter what and you are highly recommended to get a 19-inch wheel. My Rotiforms are 19x8.5 with a +32 offset, while the stock 19s from the LTZ are 19x8.5 +45, and I still needed a 5mm spacer on top of the 13mm backspace I got from the aftermarket wheels (if I used my original wheels, I would need a 1"/25mm bolt-on spacer). However, around +30 you're getting past flush into poke territory and that looks dumb as all hell.

I'm moving to a 2014+ Camaro base model 18" wheel right now with new tires, they are a factory 18x8.5 +32 wheel and clear the Brembos very nicely provided you use low profile wheel weights for balancing and do not have pads with roller skates. I would suggest something like this, as I got a set of new takeoffs with no miles or damage and brand new TPMS for $300 on facebook marketplace. It means you will not have to fuss with spacers which can be dangerous if not done correctly, and you're still on an OEM rim. Plus they look way better.

EDIT: If you're DIY-ing this stuff and not super experienced please be careful, brakes can be a pain in the butt to modify and if something goes wrong when you're driving, you'll have a bad day. Like one time, I did a brake job on my 2001 Trans Am and decided since I didn't have Loctite for the big bracket bolts, I would just skip it, well guess what next time I drove I lost a front caliper into the wheel at 80mph and ate a jersey barrier, totaled the car.
