I've seen this and that about different ways to do the front, the rear but through some unknown way, (flood/corrosion whatever it was because I just bought the fbody myself) all the brakes need replacing and I was hoping to kill several birds with one stone.

I'm looking to upgrade the front to some aftermarket rotors and LS1 calipers, and everything else from a 98+ camaro brake setup that I'll need. I'm hoping I can get the calipers in good condition but the rotors brand new to bring up the value of the car incase I sell it.

Then in the rear, I've decided to buy a 4th gen rear end from a junk yard, will there be a big difference in price from the LT1 rear to the LS1 rear? I heard it might cost $300 generally but I haven't gone to price one yet. Then after that what parts do I need to install the rear on an 87 IROC?

Finally getting LS1 brakes for the rear end, what are all the parts I need for that? Same way as the front, aftermarket rotors and factory calipers with hardware.

I would rather have gotten 4 brand new calipers but that would end up costing me an arm and a leg. Or would it? any alternatives I should know about?

For the full conversion how much has it costed you? Is $1,000 too cheap?

I don't mean to add more and more threads to tgo, I just got such a headache and i've been looking forever for all of this stuff.

Thanks

There are many threads on various brake conversions. You might consider a . Ed Miller is the resident brake guru.

I wouldn't have posted if I couldn't find what I was looking for. And doesn't ebmiller88 get enough emails a day about brakes? Every single one of these threads suggests him for help with a conversion. Honestly, I thought for sure i'd be BOTHERING him. If he wants to chat, by all means.

I searched through this brake forum all day yesterday and I couldn't find what I was looking for.

If anyone sees this thread, and knows exactly where some of these threads i'm looking for are, please oblige with a link or two.

 

I searched with "LS1 brakes" in the brake forum and came up with four pages of info to include the following, which might prove helpful:

By the way, Ed Miller has designed and sells various kits. Check with him for your needs. I'm sure he can hook you up.

JamesC

 

Thank you, I'll check them out after I read how to swap the rear ends. There's so much reading to do.

 

By the way, the 1LE option is also a good one, at least IMO. Spohn sells the front kit (Ed may too for all I know). You can mod the rear yourself. Check the following link:

I curious JamesC, what's the reason you prefer the 1LE option disc brakes over the LS1 front and rear conversion? As far as I know, the LS1 has better stopping power.

 

I have both setups

Ls1 on the Formie and 1LE on the TTA. I'll take the LS1 setup any day.

They are both new and recently refurbushed, so the comparison is a fair one.

EbMiller is an awesome guy to deal with and he will take the time to answer questions as well as anything u buy from him is priced fairly

I went with the 1LE's because that package was the only one available at the time (with the exception of the after market). I went with the rears, essentially because I wanted a matching set and also because I required a working e-brake. Without fabbing something up, I 'believe' this is a problem that still exists with LS1 brakes (not a biggie, I suppose, if you have an automatic). Futhermore, I didn't relish swapping the entire 4thgen rear end in because of its width--IMO, two inches a side is two inches a side too much. I also think there's a wheel fitment problem involved as well. Please double-check that info. At any rate, either the 1LE or LS1 or any of the other current packages will be far superior to the 10.5 Delco Moraine set-up you currently have.

I'm debating this myself...........which one is the least costly?

And............fabbing brake cables or anything else is no prob.

For what I spent on the front 1LE's knowing what I know now I could have had Wilwood 4pots for the price.

 

Well the rear end shouldn't cost too much from a junkyard but mine is all rusted up pretty bad so I was thinking of replacing. But i'm also under the impression I can sandblast it and the 1LE setup total would be cheaper. I don't know that for a fact. Wilwood is just TOO expensive.

 

Priced a full rearend with brakes from a junkyard lately? The local yards here wanted $600 for a '94 LT1 disc posi. A private buyer would be better for you. If it's just rusty, clean it up.

The LT1 rear brakes are more of a direct bolt in and you won't have to mess with the e-brake issues, LT1 e-brakes are a no brainer...bolt right in and will give you good performance.

Replied to your PM.

The issue is that when you utter the phrase "1LE", price goes way up. I have 1LEs, love them, and won't sell or get rid of them due to the time I have in them, the are one of the last sets of orginal GM 1LE parts, and if I tried to sell them I wouldn't get back what I have in them, there's just too many setups out there. BUT, they will fit wheels that other setups won't, such as GTA wheels. There's a plus and minus to practically all setups, it will depend on a number of things.

Least costly will depend on new or used parts. An all new LS1 setup will run you about $900, and all new 1LE setup is $850 from Spohn. Obviously a used setup will run less so it depends on where you get parts and if you can catch a deal.

PM me if you want my recommendations.


And to the orginal poster, IMHO $1000 is too cheap for both the front and rear setups unless you can do a lot of the machine work and modifications yourself. Again, it depends on a lot of factors.


Ed

 

Thanks Ed. I really like the 1LE fronts. All original GM parts also as I started collecting for them in 1998.

Now I really need some rears to balance the setup and it probably will be one of the "L" setups. When I get around to it that is

I can afford to go a little over 1k and around 1300 sounded good but I haven't decided on the C4 setup or any other setup for that matter, and just yesterday I came down with strep, so I probably won't make the deadline anymore. Although the car is the least of my worries. Either tomorrow or saturday i'm going to the local yards to see if I can quote a rear end.

If I decide to do business with you, I'll keep in touch. Thanks

Also, I do plan to do all of the labor, the only thing I can't do myself are modified spindles(i'm guessing, unless it's easy) and some heavy duty fabrication(if there is any).

Modification of the spindles for the 1LE set-up is relatively simple. If I remember correctly, all you need do is cut the ears off the spindle (hacksaw) and drill and tap two holes. You can purchase a CD from Spohn (at least it was available) or from AndyZ28, which details the mod. I accomplished the mod with the spindles off the car, but IIRC, some members did it with the spindles on car.

After reading again are you talking about the price for the fronts?

The rears should be a good bit cheaper than that correct?

 

I'd like to know that as well

 

I went to the junkyard today, nice place where they actually let you walk around and see the cars. Saw a few junked f-bodies. I was quoted 500 for a functional LS1 rear end(They'd have to get it from another yard). They were asking me what I planned to do with it and I told them. So then they showed me a 92 rear end with stock discs, which i'd never seen before. I thought they were rare. Anyway they were rusted up so I'm going to see if I can get this LS1 rear.

Do you think it's a good price and how much estimated should the front/rear swap cost total if the rear end was 500? This is nice, I'm finally getting somewhere.

 

get on www.carpart.com and do a search for 98-02 f-body 6-speed rear (more likely to get a good rear ratio), and bypass the junk yard markup of the middle man

 

No dice, I went to the site and it only lists 93-02 camaro's disc rotors and shocks.

*edit 500 is THAT bad?

 

Yes, the price I quoted was for fronts only. Again, the rears will depend on where you get them. The rear brakes usually go for $150-200 used, then factor a new set of rotors into that. Then you will have the issue of the e-brake cable hookup and brake lines to fit, especially onto a drum brake rear.

Still right at $1000 for all of it depending on where you get parts.

Ed

PS: IMO, $500 is too much in my book, maybe not yours.

 

Thanks Ed.

I quess it's time to start gathering parts.

Depends on what I can find at the junkyards.

 

are you asking if 500 is a bad price for a whole rear end with brakes? If so i think 500 is not too bad if a local pickup can be made and it is the newer ls1 style brakes, then it wouldnt be a bad deal. You might try www.camaroz28.com and search the classified section for someone parting out a car or offering a rear for sale. You might be able to find a better deal that way as well.

good luck
