My co passenger and also owner of a 318is was filming.
My first trackday and the car was running great. We were just in time, the day before it was ready, equiped with a new suspension (Bilstein B8 + -35 H&R), every single suspension rubber replaced, renewed every single part of the distribution and renewed most of the hoses under the intake.
Z3 1.9 ssk, single mass flywheel and Mark D. chip. The car felt great! Only minor things: the exhaust pushes against the car, so it's quite loud inside and I can't hear the engine. I replaced the centre bearing but it's still noisy.
So here's the vid:
