problems with ATE Power Discs?

[Ameer Antar]

I've tried the Powerdisks on a 5kt. Great braking power in all weather. I didn't have any warping/cracking issues. But I torqued them down myself...There sposed to be 81 ft-lbs. and most cheap impact wrenches can do 250+ max, so they might get damaged at the shop. I wouldn't trust any mechanic (unless you drink w/ him/her) to use a torque wrench, esp. on wheel bolts.

One other thing, I heard that machining rotors is not the best b/c you grind off the specially tempered surface. The grinding heats up the surface and is not like a fresh set of rotors. I guess it depends on your funds though. Machining rotors is like $25... set of rotors maybe $150.

Some of you might recall I recently posted with tons of questions about 
odd wheel noises in my '88 80Q, and alignment issues. The end of the story 
is: I'm not so huge a fan of ATE Power Discs any more. 

I had the front end of my car basically rebuilt after a track accident, in 
sequence first from totally new wheel hub, wheel, suspension assembly, to 
most recently having new rotors put on. I reported to you folks that I was 
hearing squeaking wheels and I had wheel vibration even after a (somewhat 
drawn-out) alignment which included measuring the subframe and confirming 
it was true.

It turns out my less-than-a-month old Power Discs were warped. When my 
mechanic had them machined to true them, the rotors both broke. He 
couldn't get a satisfactory answer from ATE as to why this happened, so 
instead of getting another set of Power Discs, he obtained a set of 
cross-drilled Brembo rotors. No more vibrations, no more squeaky wheels. 
The Brembos are quite beautiful.

Have any of you encountered problems with ATE Power Discs?
