The 034 team says this is normal based on my setup, which includes Carbotech XP12s for track and 1521s for street. The 034 rotors performed well until the end, I just wish they'd last a bit longer. I'll attempt the Girodiscs to see if they hold up any better (thanks Pete @ 529innovations). 🤞🏼🙏🏼

oh crap.. I'm running Girodisc front and I like those. For me it's 8-10 tracks days at VIR.
