Hello I have a '21 LT1 and want to know if I can upgrade the rear single piston

Been discussed before, really not possible due to the bracket locations and the parking brake.

If you need more braking performance, you can upgrade the front calipers to 6 piston like the 1LE and ZL1. The front calipers do 90% of the braking.

If you are looking to change the LT1 rear brakes because of some cosmetic personal dilemma, I can't help.

Sheesh if you could get some ZL1 stopping power on an LT1 you would be able to stop on a penny! Not even a dime lol

Although I also upgraded to the 6-piston 1LE front brakes after increasing my car's power level (and weight), I don't think this helps with stopping power or braking distance for the same exact car in a single emergency braking situation, it's more for sustained performance and heat dissipation.

And, needless to say, looks, which is what I suspect OP with those wimpy LT1 rear brakes is after.

Thanks to everyone that responded. That's a bummer

You would need race tires mounted up front (probably 100 thread wear) and a dry warm day to realize the additional braking performance on the 6 piston front calipers brake conversion. You won't see any improvement on street tires. You are absolutely right about repeatable brake performance stop after stop after the 6 piston caliper upgrade.

I was itching so bad for a Camaro I was willing to get an LT1. I'm glad I didn't go through with it because I absolutely love the looks of the big ass brake kit that comes with the copper-free 1LE brakes. Not that I would have upgraded the brakes once I purchased an LT1, but when I found out it's basically impossible anyways, it was just one more thing that helped sway the decision to move towards at least an SS. The rear brakes really do look severely out of place on an LT1 and more like something that would go on a Prius.

On the other side, with a 17" drag tire rear setup, you don't see the rear brakes at all.

Yea, that slipped my mind. Perfect for people who drag.

Nope, it’s not because the SS & ZL1 can run 17” drag wheels out back as well. Since GM was doing smaller brakes out back, they should have gone with a caliper/rotor combo that allowed for a 15” drag wheel. Then that would have been a win for LT1 owners.

Well ya know what I guess GM knew what they were doin as far as the step down from the SS. Wish I knew this before going w/the LT1 and my cosmetic
dilemma

Anyway back to my wimpy LT1...

Forum member Matt1LE ordered some caliper covers and painted them to match his car and now his 3LT rear brakes look just like SS Brembo rears... Might want to contact him for details...
