Ztherapy SU's, wow what a difference

Having personally seen a few cars running ZT SU's (including Steve's white 240), and the carbs themselves in various states of assembly, I can vouch for their effect and overall improvement on stock SU's.

Lots of little details are taken into account, for example on those I've seen even the throttle butterfly screws are flush to improve CFM. Probably not noticeable by more than a dyno or an all-race engine, but nice to know its there.

Perhaps someday I can afford a set. :)
