They are still not on for the fact they need to be rebuilt and powdercoated.:/

Default A few comments

<center><img src="http://www.world-challenge.com/files/photos/thumbnails/DSC_3533_720x0.JPG"></center><p>You state:

"[Belleville springs] have a very high spring rate so once they are torqued down they don't allow the disk to move. When a disk isn't allowed to expand the hat may crack around the bolt hole area. The Brembo hardware is more expensive because it was specifically designed for that application. Brembo solution is used by the few OEMs running two piece rotors, I am not aware of the Belleville Inconel washer to be acceptable when durability is of importance."

Compared to the Brembo Mclaren spring, you are correct - the belleville springs do have a higher rate. We chose to use these because of the calculated thermal expansion at the rotor flange. We specifically design our fastening hardware such that when the flange is expanding, the springs behave with approximately linear behavior (the belleville force/displacement curve is actually cubic). The force generated works out perfectly.

You seem to imply with your statement that our rotors would not properly float. This is simply untrue - if it were I'd have Chip Herr banging on my door demanding new rotors after every session. This obviously doesn't happen - in fact Chip often comes in to the pits with 1400 degree rotors. Unlike Brembo GT kits, our Alcon kits use the same exact rotors as in Alcon race applications.

Durability? We have 1000s of customers with hundreds of thousands of miles. Please don't make unfounded claims regarding our kits' durability.

Cheers,

Ted

Default Tomasz, could you elaborate on your claim regarding plating?

Default Why do you take the caliper off?

I understand if you have Alcons, where you have to take them off to swap pads. But I never took the StopTechs off.

Default That was a while ago, no, then I did not know I was going Brembos.

Let me know when they are on.

Default Hmm...

Are you telling us that STaSIS race cars run rotors with the Bellevile springs on them? I thought that they were there for anti rattle only and were not used at the track. (I do not know, I am asking. I assumed no washers on race rotors.) I am also sure that you change rotors every race...

If you look at the experience of people runing these on the street and track the story changes. There has been at least one documented STaSIS rotor failure (and few of the StopTech). My claims are founded, I am happy to link and post pictures if needed.

Default please post a link. i don't remember a rotor failure.

i remember a Stasis hat &amp; caliper adapter failing (both on same car a year apart) and i think the design had been changed for both parts before the failures happened. i didn't think either was caused by lack of plating or the washers.

there was also issues w/ APR's caliper anodizing.

i do wish they (Stasis) had some kind of plating on the rotors because the rust is unsightly and the rear pads for the TrackSport 298mm kit don't cover the rotor surface as well as the fronts so there's a ring of visible rust by the hats.
