Default Bendix rotors warped; Powerslot or go back to semimetallic?

I installed Bendix premium rotors and Raybestos Quiet Stop pads on the '98 LeSabre about 9 months ago:
http://www.bonnevilleclub.com/forum/...ghlight=brakes

They were awesome til now.

Two days ago I started getting the same 50-70mph shimmy on braking that caused me to change brakes. Well, I take the front wheels off and the rotors are badly discolored and so warped I can actually see the highspots with the naked eye.

I guess the warnings about ceramics being able to eat up even good quality rotors were true

I love the ceramics' stopping power and quietness, but I don't want to be changing rotors so often. I could either get another set of Bendix and go back to semi metallics, or stay with ceramics and try Powerslots.

What to do...

2 year only, and specifically does not cover any wear-related issues.

It is a 2 year REPLACEMENT warranty in case of defective qualities that arise during that warranty period. I'm pretty damn sure you can get new ones for free. Did you get them at advance?

I was unable to warp my bendix rotors...those things were awesome.

but personally I am a fan of only bendix pads...especially over raybestos. CT3 or TitaniuMetallic all the way

I bought the rotors on EBAY in a "Best Offer" auction. I am not concerned with warranty replacement, but rather with whether I should go "safe" and return to semi metallics with good rotors, or "gamble" on ceramics again but with Powerslot rotors.

Can anyone comment on the quality of Brembo slotted rotors?

I installed my new bendix rotors (PN 141868 from summit) back in january because of rotor warping problems. For the past months since ive been doing my best to break them in properly (limiting hard stops, throwing it in neutral at traffic lights), and now they are showing signs of warpage as well (using rabestos ceramics pads). I guess the prob could be the rears but just dont know anymore

Im with you, im disappointed, i thought this would be the end of my problems :(

Can people post their non-warping brake setup? maybe this could give us some insight.
