Reason Psymin's car was doing 12s was it was wheelspinning most of the time. I'm sure it could do better with Micky Thompson Drag tyres and maybe a slightly different suspension set up. It was very fast around Pukekohe.
My S1 is lowered on Bilsteins, has heavy sway bars, adjustable camber, pineapples, semi slicks (now slicks) on the track and handles heaps better than stock but was still getting passed by little cars with half my horsepower on the track.
I enjoy having a completely stock looking wagon which will have 300 -400kw by the time I am finished. the only reason
I don't build a track car is I am too poor.
