Struggling to really remember anything else, probably missed a couple of things, would have to read through the thread.
But to make it this good handling wise actually cost very little and it keeps it a very well mannered road car with great comfort, but surprising how incredible it was on track performance wise and so flat. Of course you could go more extreme with KW coilovers, stiffer anti-roll bars, weight reduction etc but its not a track car, my daily and fun car.
