(i seems to be in a bad karma year)

Last week i had a track day, first one.
track is known to be hard on brakes and tires.
i was running Hoosiers.
Brakes was terrible, it felt like i had street pad in front and race pads in rear.

well after a day. my ABS shut down and i spun
here are a few video of my run, you can clearly see that i have brake problem, brakes way too much in rear

Now you know why I spent the $$$ ($750) on a rebuildable bearing.

These appear to be very well built, and hopefully the last set of hubs you'll ever buy. I'm just reposting this information here; I'm not involved with this business.

Any questions should be directed to Mike (contact info below).

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:
http://www.mjmracing.shutterfly.com/

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.

We installed one of our masters on his car and he was very happy with the results. More info to come early next week.
