Is there any upgraded rotors available now or being developed for release soon? I believe our rotors are a bit bigger than what the ats v has...

not looking for bigger. I warped my stock rotors on track. just wondering if anyone produces a slotted or crossdrilled rotor that would fit in stead of replacing with stock.What makes you think a bigger rotor is needed?
Yeah i agree. i think its deposits but of course with a lot of shudder the dealer looked at it and said they were warped and i needed new rotors. Then they handed me an estimate of $2500 and I was like fuck that. could I get an aggressive track pad and wear them back to smooth possibly? I'll check with Girodisc. thanks for suggestions!Sorry to hear about the warped rotor. I will not get into a discussion wether warped rotor is a ‘real’ thing, but these rotors are thick enough that you can get them resurfaced and remove any pad deposits/uneven wear.
As for alternatives- check if Girodisc has 380X34 rings. You might be able to fit them to your OE hats. Also, Brembo GT has a standard size of 380x34, but those rings will cost you an arm and a leg.
Sometimes it works. To be honest , for $150-200 a good mechanic can resurface the fronts without sacrificing too much iron. It drives me nuts , to feel pulsation under light braking around 60mphcould I get an aggressive track pad and wear them back to smooth possibly?
Find another dealer, I've seen a couple have warranty cover new rotors.Yeah i agree. i think its deposits but of course with a lot of shudder the dealer looked at it and said they were warped and i needed new rotors.

Rotors are likely not warped , just have uneven deposit. That can happen from:What track/how much track time are we talking? Drag or road course? Kind of disconcerting that a brand new performance car would see warped rotors so quickly.
Thanks for the detailed reply, it actually brings up another question I had:Rotors are likely not warped , just have uneven deposit. That can happen from:
1. Not bedding the pads properly.
2. Pressing the brakes for a while after your session / engaging the parking brake.
3. Using too much ABS , which creates a pulsing action on the rotors.
4. Not allowing a proper cooldown lap after each session.
5. I’m sure there are more reasons besides bad engineering / not adequate hardware.
came here to say this lol^Check in with Ken at KNS Brakes.
They had rotors back then?Interesting topic. On my 2020 ZL1 the front rotors were warped at 2,000 miles. Car was never tracked. GM covered the warranty replacement as the rotors could not be turned down. I think the paperwork showed they cost $550 each.
It was the first time I had rotors replaced under warranty since buying my first new car over 50 years ago.
I had an SS as well, and knew it would set the brake on it's own, but couldn't remember the exact criteria for it. I asked in another thread, and apparently the BW will never set the brake automatically. Random fact...did you know the SS has 3 positions for the parking brake? Off, on (light), on (firm).Thanks for the detailed reply, it actually brings up another question I had:
My 2015 Chevrolet SS also has an electronic parking switch. After track sessions I use wheel chocks, put it in gear, and leave the doors unlocked so that the parking brake doesn't automatically engage. Is it the same procedure for the Blackwings i.e. e-brake doesn't automatically set when you open the door?
I use the emergency brake even with auto and I always double pulled it on my SS...I had an SS as well, and knew it would set the brake on it's own, but couldn't remember the exact criteria for it.

yeah they are not warped but bad pad deposits. I had dealer in Austin check it out as they said their techs working on blackwings and Vs all track their cars so I thought I could trust them...they charged me over $350 for inspection and quoted me $2500 on the replacement. I won't be going back to them.What track/how much track time are we talking? Drag or road course? Kind of disconcerting that a brand new performance car would see warped rotors so quickly.
