I've done the same swap on my 1LT using a set of ZL1 take offs.

Everyone above basically hit all the important points on doing this already. Figured I would weigh in as well.

From looking at your pictures, you have every part needed to be able to do this as is. Some things to note however:

1. Get new TTY caliper bolts. Everyone already said this and you stated you were going to, so your good there. While some people reuse them fine with a little thread locker put on them, IMH brakes are no place to cut corners.

2. Unless you have extra cash, don't worry about replacing any of the dust shields. These are the backing plates being discussed. I trimmed mine using a air cutoff wheel and had no issues. You will need to trim both the fronts and backs due to the ZL1 front calipers being larger. If you ever need to revert to stock you can just buy some OEM ones and put them back on.

3. Getting the SS/ZL1 master cylinder is definitely recommended but not required. I have mine sitting the garage waiting to be installed but I still feel the difference without it.

4. Same for the stainless lines. They will hold up better over time as they will not expand when braking like the standard hoses will. Many threads on the forums for this if you look around. These are also waiting to go on mine.

5. Putting DOT 4 fluid in when you flush the system wont hurt anything for sure. However DOT 4 will more readily absorb water and therefore need to be maintained more than DOT 3. Unless you will be doing hard braking to really heat up the brakes than you won't be utilizing the full benefits.


Some other things to consider as well, depending on the miles or condition of the brakes you may want to break them down and rebuild them. This really would only be need if the dust boots are in bad shape as the seals and pistons may be worn then.

When I rebuilt mine, I want as far as to powder coat them metallic candy red as they were already apart. It doesn't cost much but really makes the kit pop.

I linked a few pictures of mine to give you an idea.
