NEW RE-71RZs + SPL Arms… Sonoma Went WRONG

In this video, we head over to EU-Tech to install a fresh set of SPL control arms on the BMW M4 before mounting up the brand new Bridgestone Potenza RE-71RZ tires. After getting everything dialed in, we took the car out to Sonoma Raceway for Time Attack testing to see how the new setup performed on track. The RE-71RZs seriously impressed us with grip, confidence, and consistency, but the weekend didn’t exactly go to plan. We ended up having some rear-end carnage with the car that kept us from fully competing the way we wanted to. Even with the issues, we still managed to fight through and bring home a P2 podium finish in Time Attack.
