I've had my Ebc ultimax slotted rotors with ebc red brake pads installed for about 25-30k miles and they may be warped in the front since I'm getting alot of vibration especially at high speeds on the highway. Does that sound normal for it to be already warped at this mileage and has anyone had any luck with warranty replacement? I don't think ebc will cover this but just curious.

I was looking at Centric premium cryogenic rotors as a replacement and was wondering if anyone has experiences with this or centric? I may want to switch back to a normal rotor vs slotted /drilled.

Any suggestions on which brake pad to match with the centric..maybe try hawk ceramic pad instead?

I also considered the powerstop slotted and drilled kit with pads so any feedback on would be great.

Thanks.

 

If you have vibration, when not pressing the brakes, it is usually not the brakes.
Vibration at high(er) speeds is almost always wheel balance issues.

 

The vibration occurs when braking and i did recently get the tires rebalanced.

 

Braking shimmy = most likely warped rotors. Not sure about these after market dealios. They look nice but some are cheap metal and some are for track use(hard, late breaking, warming and break in needed). Good luck getting them sorted.

 

Im using Stop-Tech rotors. I picked them up from the tirerack, & I'm happy with them. I replaced my wrapped OEM rotors with these. I believe they are part of centric.

I had the same issue with a set of ultimax rotors and green stuff pad on a TL a few years back. They were fine for probably 10-15k after break in, but then started to give that wrapped shimmy when exiting the highway which only got worse with time. Stopping power was never an issue with this setup, but it came with a cost to comfort. I don't think I'd use them again on a dd.
