Check out my two 2:11 laps on Buttonwillow 13CW with Speed Ventures, competing in Bimmer Challenge on 12/18/2022. I forgot to turn on the GoPro at the start of the lap in the first one, but it ended up being a 2:11.468 which is a new PB for me! The next one happened a few laps later and was just a tad slower at 2:11.570.
I'm quite stoked—this was on heavy Style 261s and 300TW tires, I can't wait to try and put down something noticeably faster on fresh 245/40/17s and a fresh alignment.
Specs: Three-stage intake manifold with BMW 130i tune, Wavetrac limited-slip differential, Koni Yellows with Eibach Pro-Kit springs, Dinan camber plates, Turner intake and Magnaflow exhaust, 18-inch BMW Style 261s with 225/40/18 front and 245/35/18 rear Michelin PS4Ss, E9X 335i Brakes with Zimmermann rotors and BimmerWorld braided brake lines, Ferodo DS2500 pads (Hawk HPS rears), and a camber-rich track alignment done at Chewerks. The car came with E9X M3 control arms.
