4th gen LS1 rear disc to early f-body swap........anyone pull it off yet?

[SHANE 73Z]

Alright fellas,

I am getting ready to put rear disks on this heap of mine. I was planning around a Baer or Touring Classics C4 style rear conversion. That would set me back about 6 bills.



Now, I still have this hard-on for the LS1 rear kit. I like the E-brake arrangement and the fact that the rotor itself is a full 12" X 1". I also like the fact that the price is right as well, about half.

Now the big question, has anyone here made this fit?

I am talking to a stone stock rear suspended, no shock relocated, no nothing out of the norm fitment to the rear of a staggered shock f-body. No offense, but I dont want to hear about a-bodies as the clearance issues are much different.

I would love to pioneer this swap for all the low buck guys here, I just need a good starting point to convince me to try and pull this off. Basically I would like to know if the calipers/brackets clear the shocks in the stock (4th gen) positions or swapped side for side. I think I may have a pretty good idea to mount the e-brake cables.

Pics would be way cool as well.......

Thanks everybody,
Shane

I'm sure you've seen this website - it specifically discusses the 93-97 rear calipers and I'm not sure how different from later calipers it really is.

has some shots of the '98 and up LS1 install on a first gen. I also am about to run this same setup on my 69 Camaro. I'm just waiting on my rear axle so I can start bolting it all together.

I just finished the swap A couple months ago on my 68. What you need to know?? fairly straight forward, I took all my tips from the website dereck f posted.

what is the extra bracket he is welding on in these pics?

[Joe_Rocket]

Because of the staggered rear shocks, one shock would by in the way of the caliper when usering one left and one right bracket. So, some have gotten two lefts or two rights. ( don't recall which ). I believe in the pics you saw was the guy converting one bracket to work with the staggered shocks.

On the website that Joe Rocket posted there appears to be a spacer between the mounting flange on the axle tube and the brake backing plate. Is this spacer necessary for a normal installation or was it added for another reason?

I installed the LS 1 brakes on the rear of my 73. It is fairly easy but not without modification. I too had to use a 1/4" spacer between the caliper bracket and the axle housing. I thought it was because my axles were longer than the stock ones taken out of it. The place that built the rearend assured me it wasnt. I think everyone has done something different for the e-brake though. I used a pulley attached to the rear end, the driver side, to change the direction of the pull. It was cheaper than replacing the brand new ss e-brake lines I already had! And it works! But if you want it to look factory you will need a longer e-brake line on the driver side. Overall I am very happy with my brake upgrade. The car stops soooo much better than the disc/drums that were originally on it.
