I was thinking about upgrading to zo6 red calipers all around. I've read to do this I have to upgrade to the ls1 rear brake setup. What I was wondering if I have to pull the axles to do this upgrade?

 

I have read that LS1 axles are required for the conversion. I have also read the LT1 axles will work.

I wish someone can put this to rest once and for all.
I am wanting some rear LS1 brakes but I am waiting for a good deal.

 

Read this 3 times.

You must swap to LS1 axles to use LS1 rear brakes.

 

Whoaa, I dont know how the triple reply occurred, sorry.

Now that that is settled.
What is the difference between the 2 axles.

 

The length is slightly different and the LS1 axle is made to work with the LS1 parking brake.

 

Thanks shoe,
I think that finalizes my decision to not go LS1 rear brakes. The performance increase cant be worth the hundreds of dollars it would cost.

 

Wait, this post jUSt skrewed up my whole plan, I just bought a lt1 rear and then found a complete ls1 brake setup. now EVERYTHING ive read on thirdgen.org says it will jsut bold right up!? does anyone have pics of the problem area? is this something I can just modify? its just not making sense to me.

 

Well since thirdgen.org FINALLY got back up and running, I did a little more reseach and you CAN bolt LS1 brakes on an LT1 rear. theres a few ppl that have done it and one of them said he just spaced the caliper back a little. the rest said itw as a direct bolt up. hope that helps.
