What is CONFUSING; what caliper/rotor/hub will fit under stock wheels. I thought I was on top of all of this stuff until I started reading about Caprice rotors, 1LE rotors, and stock rotors being turned into hubs. Why? Thicker... larger bearings? Can caprice rotors be turned into 1LE hubs? I'm confused out of my mind.
What does the 1LE hub do vs a stocker hub? Is there an offset where the 1LE pushs the wheels out further, if that's true then did 1LE equiped factory wheels have a different offset?
Sorry for all of these questions but things are getting SO cool that it's been hard to find the facts. Having the sticky posts disappear and then some posts getting 544 replies, well....lol, that's just insane.
I just ordered Wilwood forged superlites and plan on running C5 rotors on stock hubs but now I have doubts that it'll fit under stock size wheels.

 

The 1LE brakes did push the wheels out father then the 10.5"s, however GM still used the same offset wheels. It is not significant enough to make much of a difference when the stock rims are used. However if really big rims are used that barely fit in the wells with the 10.5 brakes, then it will make a huge difference when switching over to the 1LE brakes. Kits like the C4HD that use the 1LE rotors as hubs will push the wheels even futher out do to the addition if the rotor being mounted onto the hub.

 

They will fit easily under your 17" Centerline rims (I checked your site to verify your rims). They will fit easily under a 16" rim even (most- that is, The only rim I've heard trouble with is the gold lace GTA rims).
The C5rotors are 12.81"- so the Wilwood Superlites will mount with an outside radius of 7.09"r on the C5 rotors. That is exactly the same outside radius I have with the 12.90 rotors and the SL-6 Wilwood calipers. (note the sl-6 calipers have slightly more clearance than the Superlite calipers.

Your mounting radius of the Superlite calipers is 3.965"r and a 3.50"spread.
The tapped spindle hole radius' (adapter bracket mount on spindle side, not caliper side) is 3.325"r. Now all you need to figure is what is the offset that the adapter bracket needs to be milled (surface differences from the spindle mount to the caliper mount faces on the adapter bracket.)

 

Thanks for that dimension, that gives me a big head start. Now I'm just going to make it on a piece of 1/4" ahead of time and use washers to align it perfect.
Out of curiousity, what's with the caprice rotors? Should I get a set of used rotors from the junkyard and turn THEM into hubs for the camaro? I just need to know now. Also, I'm unfamiliar with the bearing races. Can they be replaced? I haven't seen a part number if that's the case, thanks in advance.

I don't know any info on the Caprice rotors. As for bearing and races, they can be replaced- any standard autoparts store will carry replacement parts.

Check out the EMachineShop site for making brackets. I would draw it for you if I could but there is no way to copy and send the CAD file to you to submit to them. I could baically draw one and print it, but it doesn't show the dimensions or how to draw the part in the first place. You'd have to try and redraw it yourself in order to submit it to them for order- even if I did print one out for you. Look on my cardomain site at the bottom and you will see the picture I printed off of there site for my bracket, but you'll see there is no dimensions. My dimentions are on my sketch on the left. http://www.cardomain.com/memberpage/518752/6

The biggest brakes you can fit under stock 16" wheels are the 13" C4 HDs. Biggest under 15" wheels are the 12" C4s. C5s require 17" wheels...

Yes and no. You can definitely turn them into hubs but they have a 5 on 5 bolt pattern, whereas the 1LE hubs (and our cars) have a 5 on 4 3/4" bolt pattern...

It moves the rotor out an additional .300" and also uses a bigger outer bearing, Set 3 vs. a Set 34 for the stocker hub. I posted a pic of the 2 side by side in the big LS1 thread over in FAQ...

Yes, pretty much...about 5/8" or so wider track. The wheels are the same but the front track is that much wider (.300" x 2= .600" ---> 5/8").


The Wilwoods just might work since they're a thinner caliper and are curved...naybe they'll work...I dunno..


HTH...

ed, Spohn has the kit that I plan on making myself since they charge over $1000 more than the parts they're selling (~$700 when I priced everything out).
That's not including the spindle modifications which he charges extra for.
His kit also fits under the stock 16" wheel so it should fit under my centerline wheels.
I'm ever so greatful for the dimension of the spindle mount holes from center, that saves me a lot of fab work. I've already got the bracket up in solidworks so making it will take less than an hour. I might just go through emachine shop since the local waterjet cutting shop has shut down while they relocate.

 

I understand. As far as I know, the only wheels that kit won't fit in is the GTA crosslace wheels, other than that you're good.

Jon. Here's a pic I thought you might like to see. Here's the 1LE and "stocker" hubs side by side. Note how the 1LE hub, on the left, has a taller hub face and therefore will push the rotor out further. This is where the 1LE cars get the added track width.

Dean...you on probation again? What'd ya do this time???

Ed

 

Do you have a picture of the actual bearing races and bigger bearings vs stock size? That would be awesome info.
Thanks

 

Yes i was wondering if the bearings were different myself. Do you have a part number i was goin to buy some new bearings. What about the seals there the same right.

 

Not on me, I'm at work now. But I will be making a parts run tomorrow for bearings and other stuff so I can get a pic then.

Stock bearings: Outer, Set 34; Inner, Set 6, Timken seal #8871;
1LE bearings: Outer, Set 3; Inner, Set 6, Timken seal #8871.

Yes, the inner bearings and the grease seals are the same. Also, the 1LE outer bearing is all steel, the stock outer bearing's cage that holds the rollers is plastic (Timken bearings). I only use Timken bearings.

Im at work just went to check the bearings the 3 is quite a bit larger then the 34. Now i hope the aftermarket companys are all smart enough to put the right races in the rotors. Napa does use timeken bearing also and the numbers are the same just to let yah know. Its a BR3 at napa what is funny is the booked said a z28 used a br3 and a regular camaro used a br34 where the z28 uses the br34 also unless it has the performance package.

 

Yes, they are noticably bigger bearings.

Ed

 

The br3 was used on a 81 camaro also.
