86 Challenge 2026 Round 5 Buttonwillow The Circuit - 2:04.01 - Subaru BRZ

86 Challenge went down to SoCal with SpeedSF, this time to Buttonwillow's new Circuit. I had never been to this track and was really surprised at how fast and flowing it was. I also adjusted my car with stiffer rear springs to help more with rotation. I feel like the car is the best it has been, and I had a great time except for the fact that I finished P2 half a second off of P1 ‪@bpt582‬ 😭 00:00 - PB lap 02:29 - An earlier, neater lap that was a tenth slower than my eventual PB Thanks to our event host SpeedSF and to 86 Challenge's sponsors Racetreads.com and Yokohama. 2022 Subaru BRZ https://86challenge.us/ street class 245/40 R17 Yokohama ADVAN Apex V601 (4 prior events), 17x9 Enkei TS-V Racecomp Engineering Tarmac 2 Clubsport coilovers.
