6 Lug rotors or hub for a Camaro spindle?

I have a late 70's Z28 subframe, and have been collecting parts to get ready to clip my '56 Chevy pickup, and I'd like to keep the 6 lug wheels. Been trying to find a 6 lug hub to use on the Camaro spindles and had heard that there is a 1-2 year light duty truck hub that will fit (but no one knows the year).

Talked with a local guy on Sat who said to use a '69 4x4 front hub and '94 or newer rotor?

Can anyone confirm/deny that this will work, or does anyone know the info on the light duty hub?

Thanks, Bill

PS- Please keep the "keep it stock" comments to yourselves. I'm not looking for opinions, just some help .

I don't see anyway a 4wd hub will work on a Camaro spindle. Completely different animals. If it were me, I'd probably send the Camaro hubs off and have them redrilled.

 

Most truck rotors are going to have a larger overall diameter than the Camaro rotors, that will mean not only finding the truck rotors, but having to remake your caliper brackets.

Lot less work to just redrill your rotors.

 

And if that's my only recourse, then that's what I'll do.

HOWEVER, there is supposed to be a light duty Chevy truck hub or rotor that fits the Camaro spindle. It's supposed to be the "hot ticket", but I've searched here, Stovebolt, and 67-72Chevytrucks with no luck

 

I do a lot of brake stuff (the joy of owning a cnc plasma) and am VERY interested if there is such a beast. SUBSCRIBED.

 

Are you looking for hub as in drum brakes or a disc brake hub. Chevy trucks used a integral hub rotor setup. If you are looking for a hub look for a truck hub from the same year as the camero. You may have to screw with the bearings to get a set that mates it to the spindle.

Now as for stock who in thw world would want a stock Chevy truck on a hot rod and custom site, for me it would be dropped axle all the way.

 

Can you have the Camaro hubs redrilled for 6 lugs? Not sure if the diameter would be big enough for 6 on 5-1/2.

 

Thanks, PnB and you are correct, it is supposed to be a light duty integral hub/rotor

prewarcars4me- will keep looking and share what I find.

 

I know that this is not a traditional solution but I wonder if you contacted Willwood if you could get a hub with hat and rotor setp in 6 lug.

 

Music teacher's salary and Wilwood prices are like oil and water, man

I did find a thread on th 67-72 site where one of the guys milled the original hubs down and used them as an adapter:

 

yea but you could just buy an adapter if you wanted to go through that trouble.

Chevy didn't go to discs on their trucks until about 71 or 72, so if you want discs that is going to be where you have to look. Now the '69 Camaro that had discs used a rotor and hat, I would just about bet money that if you had an earlier truck hub that you could drill the hat and you would be set. Then you don't have to go searching everytime you need new brakes, you just replace the rotor.

 

Just feeling that if the simple answer is out there, I'd rather not go to all the trouble of machining, etc, just to have someone say-

"Gee, why didn't you just use the stock GM hubs from a..."

Between family, church, work, scouts, etc, my free time to get things done is at a premium.

 

Sorry PnB, I was preparing my little pity party while you were typing

It's a 1978 Z28 clip, so I'll probably have to look at newer truck parts... seems like '94 sounds right, but everything I've looked at is incorrect.

I did find this info as well for the Camaro hubs:

Front Outer SKF Part # BR2
Cup radius=.0500"; Width=.610"; Standout=.1350"; Outside diameter=1.7810"; Inside diameter=.7500"; Cup length=.4750"; Cone radius=.0500"; Cone length=.6550IN

Front Inner SKF Part # BR6
Cup length=.4650"; Width=.625"; Standout=.1600"; Outside diameter=2.3280"; Inside diameter=1.2500"; Cup radius=.0500"; Cone length=.6600IN <!-- / message --><!-- sig -->

 

And they were 5 lug.

 

"71/'72 truck? You are right, I put a blazer front under a 1/2 71 for a fella when I was in Mexico and he had to carry two spares.

 

There are 6 lug aftermarket rotors available
to fit 73 - 87 C-10 HD spindles.

IIRC, the crossmember bolts in.

Common swap on earlier trucks.

 

Thats why he was hoping for a 4wd hub that worked.

Maybe a Toyota (or other import) that used a 6 lug rotor and the right size bearing/races fit in? I get headaches when designing a new kit looking through all the bearing specs.

 

I may just have to pull the rotors off my daily 4Runner to see if they might work

 

If you'll look at the center picture in post 10, you can see that the rotor has been countersunk for the six lugs in the adapter. I don't understand why you can't drill the rotor for studs if you can countersink it for clearance.

 

Wall thickness of the tophat to clear the studs/shoulders.

 

They make screw in wheel studs. I ran into the same problem when I converted a Vega to 5 lug, and screw in studs took care of it. It was a while ago, but I think I had Moser redrill the rotors.

 

How about nissan pickup thay had the same 6 bolt pattern

 

I think you are pretty well stuck with redrilling the hubs you have. The only late GM car I know of that runs 6 lug hubs is a Caddy CTS-V and their front hubs are a sealed bearing unit like most front wheel drive units are even though they are rear wheel drive. The rotors are also right at 14 inches in diameter.

You might look into how close a 67/70 C-1- front hub comes to matching The Camaro hub as far as height and wheel bearing size. If that can be made to work you could redrill some rotors like the front ones off a 78 Toronado or maybe the rears off a disk rear end car with 11 inch rotors.

71- and up 4x rotors are larger
11.8" and have a much larger 4" center hole.

 

I have no idea about this, but a thought, is there something in the speedway catalog, be it an adapter for the spindle, something like I got to put tapered bearings on my '53 truck axle?(front disc brake kit). Or can an S-10 rotar be redrilled and adapted. Just a couple random thoughts.

 

Any one know if a complete 6 bolt spindle set up would fit his ball joints?

 

In the '88-'98 Chevy truck bodystyle, they had a light duty 2500 (read 3/4 ton) that was a 2 wheel drive, running the 6 lug bolt pattern. They had a 7200 pound GVWR.

Seems to me like theres a low-budget swap for the '63-'66 Chevy C10s using parts from that type of truck. No idea about interchanging with CamaroBird stuff.

 

Did you try this?

 

I was just looking this stuff up the other day.
what i can tell for sure is that the 91ish (generation 3) camaro hubs swap with 81-87 chevy trucks spindles and visa versa, with this caveat.

chevy (camaro and truck) had two braking systems, one used 1'' rotors and the other used 1.25 rotors. the components swap light duty to LD and heavy duty to HD but not across LD to HD because the spindles and bearings are different. The hubs are identical and begin with the same blank for each with the difference being the bolt pattern.

OK ^^^^^^^^^^^^^^^ is all the 5 lug stuff.
then came the six lug pattern, which is the same HD or 1.25 rotor with a 6 lug pattern. That rotor will also swap with a HD 5 lug rotor camaro or truck.

Now all you need to do is figure out what 91ish stuff fits your 197xish clip.
clear as mud right?

If you get that far and want C5 corvette brake upgrade i can tell you how easy that is too.

 

Looked it up on rockauto and that 6 lug rotor you are talking about was a 1988 2500 light duty. As for making it work with your set up, that might bring all its own challenges. Not sure about the diameter or which bearings to use, but you could again use rockauto to compare sizes and come up with some application.

 

Nonstop, will check it out as soon as I get a chance- THANKS!!!
