How much are the replacement rings? I have Brembo GT kit and the backing plate for the P* fits, it looks like the P* rotor is only a 3mm radius difference. Well Brembo wants close to $500 a ring replacement costs. I'm thinking of seeing if I can fit the P* rotors if they are cheaper.I believe the term you are looking for is "slotted" disks... And I'm impressed that they are spec'ing those. My slotted & cross-drilled rotors on my '05 V70R much improved wet/snow braking.
We do call them grooved on the other side of the pond, same as manifolds/headers. Same same though!I believe the term you are looking for is "slotted" disks... And I'm impressed that they are spec'ing those. My slotted & cross-drilled rotors on my '05 V70R much improved wet/snow braking.
Thanks for the link, hadn't spotted the thread.I asked PolestarOfficial about the rotor spec change. You can follow the discussion here:
It's very odd for a rotor to be warped at such low mileage. Here is a decent explanation of it, https://www.kaltire.com/what-does-it-mean-if-my-rotors-are-warped/. Volvo does not "fix" rotors, only replaces them. His specific dealer must have only had the new slotted discs in stock.What does warped mean.
If you got the new slotted discs, does that mean they already used the non slotted discs and there are no more in stock?
Polestar quoted, the Volvonamed rear pads are exactly the same like the Brembonamed ones. I have the Volvopads and drove 8 laps on the NOS without any problems whatsoever. P50GTs pads must have had some defect.P50GT, to be clear for everyone that was when your rear Volvo rotors had those disintegrating Volvo pads, instead of having the Polestar spec'd Brembo pads.
JAM2, this was your front Brembo rotors that were warped. Did Volvo provide any possible reasons on why the Brembo rotors got warped at such low mileage?
