Re: LS1 front bake conversion help

The easiest way to do it would be to buy a complete kit from someone.

I assume you are planning to do the work yourself though. In that case.

You need to modify the spindles to accept a new caliper bracket. In the picture you can see the original spindle on the right and the modified version on the left. As you can see you need to cut off the two OEM caliper ears.



Then you need to drill out the two small dust shield bolts and tap to the size of the caliper bracket. This size will vary depending which bracket you buy/build. It is critical to get these bolts drilled and tapped straight. If you don't have the tools to do this correctly, take it to a machine shop.





You will also need to get or make hubs. The most common way to do this is to take a stock rotor and turn it down into a hub on a lathe. There are also great aluminum hubs out there.

Once you do this its just a matter of assembling everything.

Re: LS1 front bake conversion help

In my opinion they are good bit better than the LS1 for several reasons.

- larger rotor 12.8" vs 12.0"
- stiffer caliper
- look better
- bracket design is way cleaner and stronger (see this thread for the LS1 bracket fastener sillyness) https://www.thirdgen.org/forums/brak...kes-front.html

Here you can compare the pedal travel and pedal effort in the last two columns.

Re: LS1 front bake conversion help

If you check out www.flynbye.com that will give you an idea of the different brake combos out there that have been used for our cars.

Sounds good.

What do you plan to use the car for? Street, autocross, track days?

Also, what wheels are you using?

Re: LS1 front bake conversion help

Well I'm not real sure to be honest I'm 21 and just got into the Camaro world about a year and a half ago and when I got the car if had no motor no trans and every part that could be wore out was. But the body was good and had a pretty good pain job. So I have rebuilt everything and did it the right way. It's taken a lot longer doing it that way but I know it's dependable. That's why I'm doing the brakes. But it will be street and probably some track in the future.

I'm saving up for the Z06 18x 9.5 in the front and the 18x10 in the back. I have spacers for the front and I did the 4th gen rear axle swap so the rear shouldn't need any spacers to run those rims

In that case make sure to check out the Wilwood FSL caliper as well. I put them on a 13"x1.1" C4HD rotor and they work quite well. They are also about the same price as the C5 stuff.

Inside a 17" wheel.

No problem.

Personally I would go for the 1LE. I like a nice short pedal. I don't mind the extra pedal effort. Functionally I think both will work pretty similarly. I also like that they are period correct for the car. I would say however, most people would probably like the LS1 better. I weigh the period correctness pretty high.

Now if you asked me C5 vs 1LE it would be C5 for sure. Actually the C6 caliper with the smaller pistons would be even better.

Will the C5 Braket and hub also work for the HD?

You would use the same hub as a C5 kit, but the bracket is different.

I actually have a few sets laying around. PM me if you are interested in a set. I have designed a bunch of brackets for various applications. Some more info in this thread.

Re: LS1 front bake conversion help

Now how much better is the wildwood setup compared to the C5? Is it worth the extra money?

The Wilwood setup should be no more expensive than the C5. The calipers are roughly the same price.

Both work well. The Wilwood FSL is used by many many racers. It is probably the most common racing caliper out there. And it is because its a really nice stiff caliper that is extremely cost effective. Pads are a very common size and available in many different compounds. The FSL is a less complicated caliper, the only moving parts are the pistons compared to the slider mechanism on the C5, there is less to go wrong on the Wilwood.

The other problem with the C5 is it is hard to find new calipers, most out there are rebuilt.

Pad changes on the Wilwood are much easier, there is no need to unbolt the caliper. The pads are also larger than the C5.

You will probably not be able to get the pads at a local parts store. Best bet would be online or perhaps a local racer / stock car shop.

Re: LS1 front bake conversion help

Ok. I need to see how hard it is to find the bracket the C5 caliper bolts to. Not the bracket that bolts to the spindle. I just like the looks better! And since there doesn't seem to be much difference in the two calipers except the wildwood not moving. I mite get it

The brackets you are referring to are called abutment brackets. They are quite easy to find. The part number is still active with GM. You can also get them with the calipers. Look for the note "bracket included" when you are searching.
