Stoptech washer issue

[BryanL]

I'll snap a pic this week but both of my rings are this way. Jerry-both of my rings are wallered out. I don't have much time to wait on Stoptech as I need rings for the first event in two weeks.

Are the Stoptech rotor assemblies the same dimensions as "stock 13in" replacement rotors. My question is; if Stoptech doesn't get new rotors in time, can an off the shelf rotor do in a pinch by spacing the caliper relative to the spindle if necessary?

[BryanL]

I have no idea Rob. It sounds like I can find slotted rotors. But I'm more concerned about this happening again. I have reached out to RacingBrake but didn't get a reply. I may just run the factory caliper setup instead.

I did call Stoptech today and talked to Pat who acted like he had never heard of anything like this happening. He asked me to email him which I did along with pictures. Will let you know what he comes back with.

I tend to think there is an issue with be build process on the blank rotors since the only issues we have seen like this have been from the blanks. Otherwise wouldn't we see this problem across the world with Stoptechs. Do any of the AI guys have an issue with the rings wallering out?

Ive had mine on there since 2013 and just checked them again this week. No issues. Maybe yall got a bad chinese washer batch?

There is no way the washer caused the issue.

Hub deflection makes the most sense to me, do the pads have a tapered wear pattern? I would take Aaron's brake durability with a grain of salt, I rarely see him use the brakes

Hub deflection makes a lot more sense. I'm paranoid though and check my hubs all the time. Surprisingly they last a while on a heavy mustang.

Y'all got me thinking again.

Presently I run these calipers:

I run custom brackets made by a buddy in college station to adapt them to the 4th gen f-body spindle.

They accept off-the-shelf 13x1.1 J55 rotors from the C4 'vette:

In addition I have the super awesome blainefab 3" brake ducts that seal off the inside of the rotors:

With this setup I make a set of rotors last almost an entire season before one of them will crack at a whopping cost of around $100/pair.

So I'm only around $700 in for my brakes excluding pads so far.

Now that the rules allow slotted rotors, and if I so feel inclined in the future, I can now jump to the two-piece bandwagon like everyone else for an additional $550-600, and drop 4 pounds of weight off each front wheel:

Maybe if I'm a good boy this year I'll reward myself with new shocks and these rotors.

Hub deflection does make since but my pads are wearing evenly and I could not feel any deflection at all. I changed hubs even though the one's on the car felt great.
