Bearings are overheating and the grease is failing which is leading to the bearings breaking apart and seizing... not fun when setting up for a turn @ 90mph.....
I only started running into this problem when I upgraded the brakes to a two piece rotor. My theory is not enough cooling and the heat is being transferred through the AL hat to the bearings and fucking shit up in a hurry.
Carbotech race pads aren't helping either....

This is why there are all-steel hubs available, which extends their life to up to 3 years / seasons.
This is the hardcore racing FC's...

Where might one find these steel hubs you speak of :D

Pretty sure Mazda didn't design their spindles and bearings to be thrown into corners at 150mph. Grease isn't going to help very much. Ever heard of such a thing as an upgrade? :suspect:

I will cut you.
It's actually happening on the street as well... then again... we all know how I drive soooooo yeah.... It will also happen during a 20 minutes session @ LRP.... but hauling the car from 150+ to 60 every 63 seconds with a few other braking zones in between isn't helping. I would venture that if I put the stock brakes back on the problem would go away, but times would be slower for obvious reasons. The ITS guys don't have this problem and they're putting down similar times as I am...

What are the fast race car guys running at the track? Besides I haven't seen you post anything for him stating what doesn't work and why.
Thank you.

I will cut you DEEP!
Cheapo grease doesn't work, can't handle the heat. The fast guys at the track in ITS are running stock brakes with upgraded pads, all they're allowed to do. The other classes have destroyed the front ends of the cars to get ducting to the brakes. This is what one of my winter projects is. Move the oil coolers back to just infront of the of the wheel wells and duct them from the front bumper. Fabricate a Y in the ducting to feed the oil coolers and the brakes.
Before I had some Naca ducts in the belly pan... my thought was that being a bit of a high pressure zone... or so I thought, it would feed the brakes... I'm not so sure it is.... so the front of the front bumper we all know is.... we'll see what happens next year... car is officially off the street as of Midnight tonight :(
