Its time for superstock/ GT to evolve. People who are racing these WRX's, SRT 4's, and EVO's have money and spend it. Change the rules for GT and allow 4 and 6 cylinder turbo engines to run. Sooner or later this will happen so why not allow it now? Another problem is these import drivers probably know very little if any at all about stock or super stock. Talk to these people at local bracket races and try to get them interested and involved. They'd be a great addition to the stock/superstock classes.
