All these times are impressive, but not having raced at lot of tracks . I am not sure what is fast at which track.But I know Lakeside and QLD Raceway sprint and clubman tracks well.So this is just rule of thumb times .
70 is quick ,67.00 is fast,65.00 is very fast,63.00 is exotic car fast, 61.00 is bloody fast, 60.00 or under you will have trouble convincing people that your car is legal and road reg . this is for S30 type only . Add around 2-3 seconds for the clubman track at QR
