ZL1 1LE Rotors again!?
Hello,
My ZL1 1LE has about 5K miles (that's all) but it's nearly all track miles - I rarely drive it unless it's to get to the track. About 2K miles ago, I drove home from the track and it rained - hard. I parked it in my garage and didn't think about it for a few weeks and had nasty rust spots where the calipers were. I couldn't resolve it and ended up buying new OEM Rotors. Somehow, now, again, I'm getting a horrible shake when braking hard or basically anywhere on-track. I didn't do anything wrong this time. I had a pro at the track drive it and he confirmed it's warped rotors! I've always been satisfied with the stock brake performance (though to be honest, I've never driven a car or this car with performance brakes so I don't know if there is better out there) however I can't keep replacing OEM rotors when they are not truly worn out but just having some kind of issue. Anyone have any feedback or advice? Have any of you replaced the OEM rotors with something more performance oriented and how did that work out? Last question, on this set, I gotta say I didn't do anything bad, any chance they can be warranty replaced? How would that conversation go with a Chevy dealer? Thanks guys... DM |

Rotors are a wear item. As fast and heavy as your car is, every 'x' hours on track, front rotors will need replacing. The more aggressive your pads are, driving style, pace, and race track layout all are big contributors to rotor degradation.
I have ZL1 brakes on my SS 1LE. Front rotors warp for me sometime in the 30-40 track hour range. Just another consumeable on a fast heavy car. The rears will last way longer especially if not relying on too PTM too much. There are non-stock rings and complete rotors available, but, none are going to keep you from having to change rotors on a regular basis on your track toy. |

Anyway, I'm just looking to see if there is something either better (from a performance perspective) or more durable that OEM. If I'm spending $1000, what's another few hundo's. Thanks! DM |

Another possibility, what can give you that warped rotors feel when braking can be uneven pad deposits. Find a good shop that can resurface rotors (per the service manual) to remove pad build up (or do it yourself). Then install and re-bed new pads per the manual. On track days make sure have the pad & rotors bedded in and you're doing a good cool down lap and maybe even drive around the paddock some. After you stop, move the car some after about a half hour. Same thing has happened to me.
