I forget what year range these upgrades are good for
But I dare say ALL of ours are GM 10 bolts and can do this.
This is the parts list not including the flex hoses for the rear.

FYI Anything that says Partzoneline, use GM Parts Direct instead and save $73 overall.

I'm doing it on my 78 Camaro this month, and I'm going to be doing it
on my '70 442 clone next so I'm posting it all here for you guys to review.

I've reviewed the
1. C5 rear brake upgrade options
2. LS1 rear brake upgrade options
3. S10/Blazer rear brake upgrade options

C5 is too expensive for nearly the same performance.
LS1 is reasonable but you have to fabricate an E-brake bracket
S10 is quite simply the best option.

(I have to reverify these)
C5 Caliper = 40.5mm piston diameter
LS1 Caliper = 44.5mm piston diameter
S10 Caliper = 44.5mm piston diameter

C5 rotor = 12.75"
LS1 rotor = 12"
S10 rotor = 11.6"

C5 setup = special brackets for calipers needed
LS1 setup = special brakets for calipers needed
S10 setup = no special adaptors

Wow last I had heard rear disc's required welding brackets to an axle housing. This would be much cleaner. Damn you... now I wanna do it

Can anyone say if this would work with the 14" SSII wheels though?
I know I've read that 11" rotors clear for the fronts, would that extra half inch be a deal breaker?

On the setup above still can be done but that only works as is with Chevy 10 and 12 bolts. Olds rears with bolt in axles require some head scratching to install just like the LS1 setup I have is. As for cable bracket fabricating to do LS1 brakes you can modify the original GM brackets to work. Complete LS1 rears can be had for 300 and less all day long. It will come with all parts you need to do the swap but again its not a 100% bolt on. You have to get creative on how you hold the axles in place with an Olds rear. I did it some machined spacers but I have another idea on how I could do ita different way. If you look around you can find just the brake parts for even less. I have about 350.00 in my whole rear brake system including the powder coating.
