MJM Racing is proud to present the first rebuildable, adjustable and regreasable front hub for 4th gen F-bodies. As most of you know already, these have been a long time coming and have gone though several interations and lots of testing over the last two years. If you've ever autocrossed with 315 Hoosier's or Kumho's, you know why these were developed.

Pictures can be seen here:

Highlights:

1. New forged and hardened 4340 steel spindle made by Mark Williams Enterprises to MJM Racing, LLC specifications
2. Timken tapered roller bearings
3. Factory ABS retained
4. Original exterior dimensions retained for a "bolt on" application with no other modifications required.
5. Adjustable for bearing play, regreasable and rebuildable.
6. Comes with new ARP studs

We will begin to take orders on 1-1-09.

We need to get at least 20 pairs in the initial order to get the best pricing on machine work and parts. Please post any questions as well as stating your interest so a list can be compiled.

The initial price will be $650 each plus a core. That price will apply to this first initial offering only and these are only offered to the people of this site at this time. The core charge will be $100 per hub if you do not have any old ones you can send. Frankly, cores are necessary and if that ends up being too low of a core charge to get people to send cores, it will go up. Please be considerate and at least knock the big chunks of rust, dirt and grease off before you send them. If you have already sent cores to help with development your names are recorded and you need not send any additional cores (unless you want to).

Our lawyer has prepared a document that must be signed by each interested party prior to any transaction. A copy will be emailed to all who state they are interested in purchase.

Please post all questions here or call me, my PM folder is already a bit full.

Howdy,

Anyway.. Sorry for sh*tting up the advertiser thread. Kevin, feel free to remove all this crap.

Short version is that I think the hubs are legal in FS and don't have a problem installing them. Protest me if you disagree.

I don't mind you adding to the thread Mark. The fact is, legality in certain classes is important to some and as soon as we have an official answer I'll post it up.

I know the SEB/SAC/SPAC are considering this now. So, if you want these to be legal, it might be helpful to send a letter in support of them. If you do so, please be brief and polite. You might even want to send a letter similar to mine restating the question rather than simply supporting my request. I wrote my letter from the perspective of a competitor, not as the owner of the product.

This is what I sent:

Dear members of the SEB,

I am writing you to make sure a certain part I would like use is legal, I believe it is, but would like confirmation. The part is a front wheel hub for my 2000 Camaro SS that I drive in E Street Prepared. On this model, and all 1993 through 2002 Camaros and Firebirds, the entire hub assembly must be replaced in order to replace the wheel bearings as the hub is a sealed unit.

I use 315/35/17 Hoosier tires on the car for competition and the added grip causes the hubs to wear out very quickly. I have been averaging 10 runs on new hubs before they are worn enough to need replacement. I have tried AC Delco from the dealer and Timken hubs from Autozone with similar results for each brand. When they wear, the bearings get play and the wheel moves in ways it’s not supposed to. This movement is transferred into the rotor, which in turn knocks the brake pads back away from the rotor. As a result, the brake pedal travel becomes very long and occasionally goes to the floor on the first application after a few offsets or slalom cones. When the hubs wear to this point they must be replaced.

I have found a hub by an alternate manufacturer that seems to last much longer. I used it all summer season in 2008 without the bearings wearing out. In fact, they are still in good condition. It is a direct replacement that is dimensionally, visually and functionally essentially identical to original or auto part store replacements. Visually, it is nearly impossible to tell one from the other. I have attached a photo of an AC Delco Hub from the dealer and the hub I would like to use.

Obviously, there is another difference other than simple longevity, or I wouldn’t need any confirmation of the legality in ESP. Unlike other replacement hubs, this one is rebuildable. It uses typical tapered roller style wheel bearings and races. So, not only does it last longer than any other replacement hub I’ve used, it can be rebuilt for a fraction of the cost of other replacement hubs. I believe the rebuildable version meets the requirements of the rule below because it is essentially identical to standard hubs in every respect except that after the initial purchase, it can be rebuilt for far less cost. Otherwise, it replaces the original hubs exactly as any other replacement part would. The only drawback to the rebuildable version is that it is slightly heavier, approximately a half pound, than the original hubs. But, for me, not having to replace them every other event far out weighs the weight disadvantage.

From the 2008 Solo 2 rule book:

"Alternate components which are normally expendable and
considered replacement parts (e.g., engine and wheel bearings,
seals, gaskets, filters, belts, bolts, bulbs, batteries, brake rotors,
clutch discs, pressure plates, suspension bushings, drivetrain
mounts, etc.) may be used provided they are essentially identical to
the standard parts (e.g. have the same type, size, hardness, weight,
material etc.), are used in the same location, and provide no
performance benefit. The allowance for use of such replacements
does not include camshafts, differential covers, or ring-and-pinion
sets, nor does it authorize the use of piston rings having different
configurations (e.g. “Total Seal”) from those of the original."

Please let me know if there is any other information I can provide to help you make you decision.

Thank you for your time in considering this matter.

So, if you have any other angle you think might help convince them or you just want to let them know how you feel, it can't hurt.
