SinthetikIroc · 03-18-2004, 09:06 PM

in the process of reading all this if i did see it i have forgotton by now,

wil this setup fit inside my stock 87 iroc rims?

if so then im def gonna start collecting parts for this

and also. i read along the way, the spindles with the raised bosses, not sure what that mean exactly just yet, but what years shall i look for to get these spindles?

and also, is anyone makin brackets for sale?

if somebody had the bracket and the spindles already to bolt on, i would interested in buying. as these 2 parts would be hard for me to get taken care of.

ebmiller88 · 03-19-2004, 08:10 PM

Yes they'll fit your Iroc rims, no problem.

Sent you a PM.

I think I remember seeing somewhere that Baer uses a 1/4' bracket for their setup (maybe that was the C4 page). So uit would probably work OK. I already went down this road with my brackets when the 3/8" ones turned out to be too thick. I opted for the 5/16 steel. I just wanted some extra thickness working for me.

I bought my steel at a scrap yard for only a few dollars a piece. You have probably already thought of this Ed, but if not try checking one of these places or the scrap pile at a machine shop, fab shop, welding shop etc. Of course I was only looking for enough to make brackets for my own car. I guess this may not be a practical approach if you are working at a larger scale.

I have noticed a potential problem with my LS1 calipers. I am having trouble getting the bleeder screws to seal. I am seeing brake fluid seep up around the threads. Tightening the bleeder doesn't seem to help. The fluid is not coming up through the center of the bleeder like it does when the screw is loosened. I have thought about this a lot and cannot imagine how this could be happening. The area around the bleeders had a fair amount of gunk when I bought them from the salvage yard suggesting that they may have been seeping fluid on the donor car also.

If this continues, I will trade the calipers in for rebuilt units but I would like to avoid this if I can. Any ideas?

just get rebuilt calipers. altho there isnt a store near you, my job sells those calipers for 39 bucks each and they have a lifetime warrenty.

so im sure somewhere along the line where you are located you can find some for not too much money

ebmiller88 · 03-21-2004, 08:15 PM

I didn't know these calipers were in the aftermarket yet, good to know. Where would I buy them, by the way?? The only thing with that is you'd still have to get the carriers and pins, etc, and I'm finding those are hard to find all by themselves.

I've had good luck buying clean calipers so far, no problems like you have, Chuck. The yellow calipers I did were so clean you could eat off of them...real nice.

I know that Baer used 5/16" in their Track systems, Luke got that thickness for us in the C4 threads, and I assume that Baer sticks with that thickness since it works for the LS1s here also, and their hubs no doubt are the same. I did get some 5/16" thick stuff but not a whole lot, and I'm having trouble finding any that is scrap. We have all the 1/4-1/2" stuff you'd ever need at work, and a lot of scrap, but no 5/16" anywhere...they just don't use it. I'm still looking for it on the cheap but I'm busy with the 13" C4s at the moment.

nastra and wagner both make them. so if you are located in mass. you can hit up a consumer auto parts and get the nastra calipers for 39 a peice. we also stock carlson brake parts,they make all the hardware and what not but not the carrier, but i think if i remember correctly some calipers come with it already.

just go to any parts store. they should have them.

novass · 03-22-2004, 06:45 PM

I was able to save the bumpstop on my conversion, I removed some of the bumpstop to clear the 12Mx1.75 12.9 socket cap screw,fits great. There is still plenty of metal to hold the bumpstop in place. I have several other things I have done that my help others out in their conversion, I will post them when I get pictures of them.

Just thought I would share.

slayer2000 · 03-22-2004, 07:00 PM

I used countersunk bolts for caliper clearance on the other side, but I guess you could use them on both sides and you wouldn't have to grind anything. I wish I had known before hand but that's life.

ebmiller88 · 03-22-2004, 07:27 PM

I applaud your efforts but I gave up on the steering stop on both the C4s and LS1s a while back. In the pic you posted, notice the shiny area in the middle of all those dots near the lower bracket to spindle bolt (it comes thru from the rear in the pic) and to the right of it. That's where the A-arm stop actually hits the spindle, nowhere near the actual steering stop cast into the bottom of it. That's why I choose to just cut them off.

(Not bashing you here, just giving my insight.)

Looks great though! Since we're giving insight anyway, I have changed the way I do the spindles a bit. I tap the lower spindle hole to a 7/16"-14 thread instead of the M12 x 1.75 I used to. By doing this it means a smaller hole in that area and therefore leaves a little more metal around it. This was brought up earlier by Tim (TRAXXION) and this is how I've chosen to deal with it. I still tap the upper hole M12 though, until I run out of metric bolts, then I may switch to a standard 1/2" bolt.

empty your pm box! i want em!

novass,
Where did you get the alen head bolts??

Local industrial supplier. They were like .45 apiece.

I know that McMaster Carr.com has them on their web site, for a box of 25 its a bit over $8.

ebmiller88 · 03-23-2004, 07:27 PM

I've gotta get those Allen bolts too. The Monte Carlo LS1 kit I'm working on requires them.

Ed

z28cdoyle · 03-23-2004, 08:46 PM

I also used standard thread bolts to mount my brackets to the spindles. I don't have anything against metric bolts but everyone else around me seems to. I found it nearly impossible to get metric class 10.9 bolts locally. Of course grade 8 standard stuff is everywhere and costs much less. I had no choice for the carrier though and finally found a source for the metric stuff.

BMmonteSS · 03-24-2004, 09:13 PM

Ebmiller: I started a thread over on montecarloss.com about my LS-1 swap. Those allen head bolts would have allowed me to leave a good bit more material around the bolt bosses. If you haven't looked at my post there are some pointers in my post as well as some pics. Over all it looks like the monte swap is a little easier than the camaro swap.

ebmiller88 · 03-24-2004, 09:34 PM

Yep, I've seen it and I think I replied to the stud question in it. The Monte mods are indeed easy but after doing the Camaro spindles so long, they're easier for me.

After semi modding one spindle to accomodate hex head bolts, I realized that the Allen bolts would have to be used. I've almost got the setup ready to go, just have to tweak it a bit. It does fitup better than the F-body kit though, not as much interference with the brakes.

novass · 03-27-2004, 06:12 PM

Well there done! Except for installation in the car. First Pic of the spindle/bracket. You can see where I milled down the bracket in two spots to center the carrier on the rotor. Also, how I milled the height of the one hex bolt down to clear the carrier. Then I powder coated everything.

novass · 03-27-2004, 06:13 PM

calipers

novass · 03-27-2004, 06:14 PM

complete. I am amazed at their size compared to the wimpy original ones.

lock · 03-27-2004, 07:10 PM

Looking good Novass!

ebmiller88 · 03-27-2004, 07:21 PM

Nice!!! I saw where you had to mill the plates down, and I've realized that 5/16" thick steel really should be used on the LS1s. I got 3/8" thick stuff to fit on Mark's car somehow but it didn't work on the kit I sent to a guy in Illinois.

They really are BIG!

Ed

novass · 03-27-2004, 07:55 PM

It is odd about the bracket thickness. One spindle I did not mill anything off of the bracket and it was fine. The other I had to mill off to get it to fit. I got the spidles given to me, I am assuming that each were from different years because the castings had different markings, however, they both were 'old style'.

ebmiller88 · 03-27-2004, 08:29 PM

I noticed that in the pic you posted but I didn't address it. Funny you should mention that...the kit I sent to IL, the buyer said that on one side he used the 5/16" bracket and the 3/8" on the other side, and all is well. Weird huh??

Ed

SinthetikIroc · 03-27-2004, 08:51 PM

anyone have any carriers for sale? as this is the only peices i need

ebmiller88 · 03-28-2004, 07:05 AM

If I had an extra set of brakes I'd hook you up but I don't. How soon do you need them? If you can hold on for 3-4 days, I can send you a pair.

Ed

SinthetikIroc · 03-28-2004, 07:29 AM

not in a giant rush really. i have just been unable to locate a set.

novass · 03-28-2004, 05:41 PM

I forgot to mention that these fit behind the 2nd design 16" Formula wheels(I posted a pic earlier in the thread) with about 3/16" to spare.

You can get them at a GM dealer for about $30 each. I found this part number 12455799 but I do not know if it is for a corvette or a camaro (which do have different mounting brackets) so you will need to go to a dealer and have them look it up.
