SKF Bearings Wheel Bearing and Hub Assemblies for 1997-2008 CORVETTE, 2004-2008 XLR - BR930099
Part Number: SKF-BR930099
$107.99 (1pc each)
I do not have a dedicated track car, although I track when I can. Honestly, mostly highway, very, very spirited driving when I can (I have a few back roads near me that are very fun). Tail of the Dragon and the Triangle every year with a few passes each.
I'm not the one with all the input on these but the gyst of it is that the X-tracker survives a lot more abuse from racing slicks and heavy braking without having to be replaced for a longer period of time.
I have seen some racers argue that the X-tracker is a must for the rear but that a lesser piece can be used in the front for track cars.
For a street car I don't believe it will be necessary. We're just not abusing the car as hard or for nearly as consistently long as on a track no matter how aggressive we think we are being.

My I suggest an alternative. MPI offers one that seems to fall between a full on track hub and OEM. They seem to be popular with the drift crowd with some pretty good reviews. Priced around $200 each. Part number RW 513-30.

That was going to be bearings I get when the time comes. Been looking at your suspension upgrades with great interest. Everything rubber is 25 years old now, like the control arm bushings...I have the SPI site bookmarked for when it is time. I still need to do my spring Corvette inspection to look, listen and feel how things look in the suspension/bearings. The Bearings are on sale and have 153 bearings in stock. Made in Wauconda, ILL, which is right up the road from my work.
I am very curious the change from 129.000 miles OEM parts to all new/upgraded parts as well. It does eliminate seeing a single item improvement however everything I replaced was on it's last legs. I am on the hunt for another rear sway bar, I have been informed running a 305 rear tire and a Z06 C6 rear bar could result in an oversteer surprise.
Very much concur with the suggestion that you look into MPI bearings. They are absolutely much better built, definitely more robust than stock or stock equivalent bearings. My conversations with the people at MPI and their guarantee that they’d last through many seasons on the track was enough to sway me away from the X-Trackers at twice the price.

I looked into them, I've seen reviews where they do not last as long and have leaked.
Mpi was the one suggested for the fronts for track cars trying to pinch a penny. The general concensus among those driving hard is that the x-trackers pay for themselves in that environment. Mpi is presumably a great upgrade for street cars, though for street cars there is no need for more than a well made Delco gold series replacement.
That is my understanding as well. Why I think they are a good in between for someone like me. I don't regularly track the car, 4 times a year maybe OTD. Nothing competitive. I DO drive pretty aggressively in the bends when reasonable and the car will have a LOT more power and a manual in the near future.
I'll never use anything but the X-Tracker again, everything else fails in pretty short order. The first time I did bearings I didn't listen to folks, ended up doing them again in under 10K miles on a street car.
Summarizing my interpretation of the review from another driver who has a few dozen HPDE events on the MPI, not me, I havent tried them yet:
The MPI is better than stock, not yet better than SKF, but they're working on it.
If there is an issue/defect with an MPI bearing, they are responsive and send out replace bearings right away.
Some are running MPI in the rear to save costs, and either still testing MPI on the front, or staying with SKF on the front.
If MPI warranties and replaces their bearings.... then the temptation if I were in the market would be to buy 5. If you manage to kill one, you slap the spare in and wait on the replacement. Always keeping a replacement par of 1. That's how I'd roll if I were a track junky trying to save money and time.

MPI released a new, more robust version. They told me that these were extensively tested and vetted by test engineers. Just finished installing mine over the weekend. We'll see how these hold up.

Is there a different part number for these or is it an update?
Any status updates here?
Are these MPI hubs holding up to the abuse of a track car?
Too early to tell - I only have about 5 or 6 sessions on these hubs as my last 2 track days have been cut short due to unrelated failures. My ABS codes and traction control issues haven't made a comeback, so that's a plus.
