Hub, Alum., 80 Newer, 5 x 4-3/4", 5/8" Fine $220.00

They are made for a monte carlo
Anyone think these would work on our spindles?

 

I believe those are still A-body hubs.

The MonteCarlo's where A-body platforms until 1982 when they switched the '82 design to the G-body platforms.

G-body hubs will work, but the A-body will not.


I have custom made G-body aluminum roadrace hubs made from GlobalWest on my F-body Camaro right now on factory f-body spindles- but my entire brake setup is custom built to them from ground up. The offset is different than a turned down f-body rotor into a hub.

 

Coleman does offer a Camaro hub, I just haven't bought one to give it a try yet but I do plan on it. The only thing is that the hub OD is 6.250" so you'd still need to have it turned down to fit in to C4, C5, and LS1 rotors or use a custom two piece rotor with a big enough hat to fit it into. Here's the link to that:

Ed, Those are definately for the second gen Camaro's and will not work on our 3rd gen spindles.

I looked into them before I had mune custom built from GW.

The offset is different than a turned down f-body rotor into a hub. That's what I was told over the phone, I shoulda asked when they were coming out with alum. thirdgen hubs.

The MonteCarlo's where A-body platforms until 1982 when they switched the '82 design to the G-body platforms.

G-body hubs will work, but the A-body will not.

So your saying they should work bearing-wise on the 80 to present design, just a different offset which would require a special thickness of bracket for mounting the caliper C5,C4, er whatever. I was also thinking the wheel studs would need to be changed, that parts easy enough' though.

How much did those cost from GW?

 

Thanks Dean...I'm putting together a front setup for my '70 and will probably use those hubs and taper them to 6" to fit either C5 rotors with C5 calipers or a Wilwood setup.

On a side note, a lot of guys in the 2nd gen crowd use C5 calipers and such with the 13" HD rotors. There's only .15" difference in thickness so it should work fine.

Ed

 

I believe but don't quote me that the spindles those hubs are for are thicker and longer than our spindles so even bearing and race swaps won't work.

The ones I have from GW are actually a CAD file they had on hand already for a custom application they made specifically for Wilwood (as a sub-contract) when Wilwood was putting together a custom brake setup for a customer on a 4000lb roadrace G-body car.

Doug charged me $500 total for hubs, studs bearings and races shipped to my doorstep.

There are a total of 3 threads on this build under " VSixtoy ". Here is the first of the 3 showing the hub separate from the hats and spindles.

I test fitted one of my hubs on hand on the 2nd gen spindle and using a Set 2 outer (2nd gen outer) and Set 6 inner it fits great, but like you mentioned the spindle nut went a little low on the spindle and fully exposed the cotter key holes above the castle nut. I guess you could just use two washers under the nut and cure that issue but I don't know if I really like that or not...I'll just wait and see.

Just a last bit of friendly info, You guys do realize that those Coleman hubs are $220 each and then you still have to buy the bearings and races separate. Thats going to put it with shipping and everything up to about $500 for those also and then you still have to have them machined from what you are saying the OD is too large to fit inside a C5 rotor.

Plus, the studs are 5/8, ours stock is 12mm (For reference, 13mm is 1/2"-what I have), those are closer to almost 16mm so you will have to have your wheels drilled also. 1/2" you do not.

I would strongly suggest doing as I did and contact Doug at GW for the ones I bought.

 

Dean, didn't the ones you have, have change your offset, which means spacers to get everything to re-align, so that your scrub radius is unchanged?

 

The ones I have had an offset very close to the 1LE rotor faces. I can not recall offhand exactly where they were (I search and check)

But the spacers I had made were so I could run "rear" rims on the front. I have 4 "rears" on the car so I can rotate them.
again, I'll do a search and get that info on the hub face offset comparison and the overall rim center (aka current scrub radius compared to factory 1le brakes with a "front" IROC rim.)

 

John,

A stock rotor face mount (iron caliper 10.5" rotor) where the wheel would touch to is 0" for our "reference standard"

A factory 1LE rotor face is outward +.318"

Mine with rotor onto the hub (so hat and hub together) is only +.149" I would need a 3/16" spacer to mount a "FRONT" IROC rim on though so the caliper will not hit the spokes of the rim since my calipers are large. So the offset and the spacer combined gives a total mount face of +.337"

Its very close to a 1LE factory setup; ( +.318 compared to +.337)

Yet, I use an aprox 13/16th (.818" to be exact) hubcentric spacer to compensate for the 16mm difference in offset of the "rear" rim as opposed to the "front" rim. So the 3/16 (.1875") spacer needed for the fromt rim to fit, combined with the 16mm(.6305") difference of using a rear rim= my .818" spacer I had made .[sidenote: I am using 3" long by 1/2" ARP wheelstuds on all 4 corners, not the factory 12mm studs]

A C4 rotor w/factory 1LE hub (turned down from a 1le rotor) really push things out to +.618

My overall setup is very very close (we are talking about .019" difference) from a factory 1LE car scrub radius.

 

Dean,

Thanks for the math on the offsets!!

I have always wanted to know those dimensions.

SDIF

 

Your welcome.

I have that and several other good info already on those 3 Wilwood build threads. I have spindle /bracket bolt radius' on there also which is improtant and useful info in making your own brackets for any type of aftermarket caliper.

 

Thanks for the info on the coleman hubs guys. Looks like Global West is the place to go for aluminum hubs if anyone is looking.

I won't be ordering anytime soon, the coleman hubs would have been no shipping cost for me and minus the lug nuts could have cost even a few bux less.
