I've been toying with this idea for awhile, Custom made front hubs. Any modified cast iron hub is way to heavy IMHO and this is a better option. Plus I can compensate for the rotor hat thickness and make them with any bolt pattern out there. The pictures also show my new front brakes for 84-87 cars that us the Buick enclave rotor and an 88 Fiero caliper. This is by far the lightest combo out there in a 13" size. Will be selling those swap brackets shortly. The hubs weigh around 3lbs and the typical modified weights 7 lbs. Im machining them from 7075 High strength alunimum.

This is something I have been thinking there could be a relatively big market for- Everyone who is not trying to restore to stock their Fiero is putting larger brakes on- and then you gain more scrub radius-Which is already too big on the 84-87s. Some aftermarket company apparently did this a while back, but stopped. I think they were failing- if you can make it strong and prove it in a few of the vehicles that are raced, you'd really have something. Your brake bracket is a real beauty- I'd expect this to be also. I like the large amount of webbing I'm seeing on yours. Let us know when you are ready to sell them.
They are ready now. I have had testers running them and running a set myself. No track testing yet as it's been winter in most parts. I would love to get a set in a racers hands, know of anyone??

No I don't...How much are you going to charge? What you really need is someone to run the crap out of them on a track, even a few excursions. I was looking at some hubs sold in Europe for German Opel front ends(Used for kit cars- including Lotus 7 kits, I believe) but it was for 4 lug wheels, and their webbing was so thick there was no way to redrill them for 5. Yours are 7075, so they are basically as strong as a steel one of the same shape.
A little back story; My Father owned a Jowett Jupiter- A truly bizarre British car(Even by their standards!).....Flat-4, water-cooled with the Radiator behind the engine, with Torsion-bar suspension front and rear, a column shifter- They won twice at Le Mans in the 1.5L class. The reason the company went under was because the cranks kept breaking- There were no fillets, so it was easy for a crack to form. They corrected the problem, but it was too late. Your hubs look like they have fillets, so they should be very strong!
I'm charging $400 a pair. No sharp corners at all. The Webb's are 1/2" thick with .125 fillets. I've been making aerospace parts for 8 years and toolmaker for 16. These hubs are STRONG, need to find someone that can beat on a set.
I'm very interested in buying a set- But I probably won't qualify as a good testing subject- I hit some horrid bumps sometimes- But I make an effort to avoid them....And I have some high-quality performance tires, but they are AS and only 205/225 wide. I am, however, sideways around most freeway cloverleafs. I also have a set of your brake brackets to mount the 88 calipers w/Vette 12" discs....I can machine them to fit the new offset, but do you have brackets made already- Yours are nicely painted, and if I machine mine they will be either contacting Steel to aluminum, or I can paint them- What paint would you suggest to touch them up?
I'm very confident in the design and material, not concerned with failure. If I made you a set with an offset face all you would need to do is remove 1/4"-5/16" off the bosses where they bolt to the knuckle. And possibly shorten the bolts if they contact anything. I powder coat them but any black paint would protect the area you remove material from.

Those look really good .The AL hubs that failed were made by RCC .I had a set , but I sent them back because the discs that the kit came with had too sloppy of a fit on to the hubs . They did not have the extra gussetting that these hubs have .I use Street Dreams drop spindles and they came with AL hubs as well but much heavier duty than the RCC .The other advantage with Street Dreams is the wheel bearings are from 3rd gen Camaro/ Firebird and are bigger and stronger than Fiero bearings . Street Dreams spindles are no longer available . If I did not have a set already I would jump at a set of these hubs .Great work .
I like the concept of the lighter aluminum hub to offset the weight of a larger rotor. The flexibility in offset and wheel patterns will also be beneficial.
I like those '88 Fiero calipers up front. That looks like a great option for those of us who have a pre-88 Fiero with the '88 cradle swap.
I actually ditched my C6 setup up front for them. Better fit for the car and way less weight. My car is an 87gt with and 88 cradle, 13" rotors on the back also.

The bonus of being lighter set aside.......
The ability to do custom bolt patterns will have people jumping all over these! There are a lot of people fighting with wheel offset and such with adapters to make nice looking wheels work. Compromising by having the wheels stick out a little to get the wheel to work. The ability to make the rotor to fit virtually any wheel on the market, no adapter plate required, is a HUGE PLUS!
Great work!

I'm using the stock bearings. Looking at the load ratings and the weight of the car they are more than needed, just keep them well greased, I also used the stock bearings because they leave more material in the hub for strength.

I think most people that want to use other bearings, want to do so because OE Fiero bearings are no longer available, and the replacements are generally nowhere near as sturdy as the stock bearings.

For what what I use the car for the 13" enclave rotors and 88 fiero calipers is perfect for me. Great peddle feel and braking power, feels like a modern car. I also have the "S10" booster and full size blazer master cylinder. I will have brackets for this swap available soon.
I'm sticking with the stock size bearings, they are more than ample for the weight of the car. Even on the track. I'm using premium Timken races and bearings. I can drill them to any bolt pattern you want.

Just to verify, I've been running the stock front wheel bearings in endurance racing, have about 60 hours on the original factory wheel bearings that had 80,000 miles on them before going racing. No issues despite sticky tires and pushing hard. Repacked three times with quality grease.

My Fiero 3.8 turbo sees trackdays quite often. If I had the spare cash, I would be interested. I've allready had a machined down disc/hub crack near one of the wheel bolts. Regards, Rafe
I'm interested in a set. I've been a racer for past 7 years (Racing Spec Miata's). I am also a member of the Maritime High Performance Driving Club and run my 1984 Fiero Custom w/355 SBC swap at 12 to 14 track day events each season. Tight and technical race track that puts lots of stress and strain on bearings, spindles, etc. (www.atlanticmotorsportpark.com). I am also an Engineer with 30 years of mechanical systems R&D and testing experience. Perhaps we should talk?
I have a set and they are very nice.....Sluppy123 had a posting in the Mall(Edit; Last posting May 2017)....You may try searching(Google search; "Aluminum brake swap hubs Pennocks") for that or possibly sending him a PM....
