I own a WS-6 and a SRT-6. The SRT-6 is faster out of the hole and to 60 but from a fast roll the WS-6 just pulls and keeps pulling. I also have a G35 coupe (350Z in a tie). It carves corners even beater than the 350Z according to the mags. So don't race one those in the corners!! The SRT-6 is just fun and very quick off the line and great in the corners.
