I'm not if any of you remember me bragging about how my rotors weren't warped after 12K miles, even after i had road raced it, autocrossed it, etc.

Today, coming from a 110mph frantic slowdown (racing some guy in a mustang on the freeway)...i see some cars up ahead so i brake hard. the shake down began! The car shook right up to i hit about 60mph. So, i did some braking tests the rest of the way to work.

from 60-0, hard braking, no shudder.
from 40-0, hard braking, no shudder.
from 110-60, soft braking, no shudder.
from 100-60, hard braking, shudder.
from 80-40, hard braking, little shudder, if any.

So, i'm happy it only shudders at higher speeds, but, eventually, i will need new rotors. At 15K...my Max has succumbed! My rotors are warped. Noooooooooala ObiWan in star wars episode 1ooooooooooo

 

I don't know whether to laugh at your comments or feel sorry for you..... both sounds good. Welcome to the "Warped Rotors Club"

 

My GXE with 30000 on it does shudders at all speeds. It just happens to be a little scarier at high speeds.

 

mine does that sometimes and sometimes it doesn't. It is really strange. Sometimes braking from 90mph I feel nothing and sometimes braking from 60 mph I feel a slight vibration. I have 7700 miles right now....maybe I will get the rotors fixed up per the TSB at the next service....

 

That's funny cause my rotors we shuddering at like 30-0 speeds.
