I am still mentally putting together my B-Street suspension. To that end, I am working separately with both Ground Control and TC Kline on two different B-Street legal comprehensive solutions.
I would love to here about the experience of others in this endeavor.

My car is a 3.0si Roadster that started with the M Sport suspension. Current setup is Koni Sport struts/shocks, H&R front sway with Ground Control adjustable end links. Still running the M Sport springs. Wheels are stock Style 108 at 18x8 front, 18x8.5 rear. I'm currently running Hankook RS-4s, 245/40 x 18 front, 265/35 x 18 rear. I was running same size RE71s and decided to give the Hankook's a try. They're a good choice for a lower cost tire but they're a tick off the RE71s. Just got delivered today a set of Flow One Race Spec F2 wheels. 18x8 ET40 for the front, 18x8.5 ET42 for the rear. Going to run 245/40 RE71s in the front and 265/35 RS4s in the rear since they've done fine there. The new wheels with the 265/35 tires will be my track day fronts so I'll have a square set of 265s for the track.
I won B Street locally last year and again this year with the car, but just barely. At state championships it's taken a 5th and a 3rd. At a national tour event I don't think I could trophy with it in B Street, but I may run a couple events in 2018 since non-M Z4s will likely move to C Street next year. I'll have to see how it fares against ND Miatas which will likely be the majority of the competition in that class.
