I disagree. It think a 370z could be developed into a 430 beater. Just would be very expensive. Extensive lightening, lots of suspension work, huge tires, and ground up turbo build. But your talking $1ooK of work.
My $15k 200 hp Porsche 914 race car had opportunity to chase a 430 all day at Laguna SECA Granted driver wasnt pushing the car to limits but chase footage is still classic. I love it when he dusts me in straights only to have me reel him back in in the more technical sections.
