Personally, I really think the SCCA E/Street Prepared (basically, I refer to the "Street Prepared" catagory) concept of their rules are very, very good and keep the cost reasonably down and to the benefit of the average wrenching garage do-it-yourselfer car nut.

I would only request of them (the SCCA) to exit certain vehicles which they've recently allowed into the E/SP class (the little foreign imports have too much advantage in their short wheel base configuration). In other words, I'd favor more Classic American Pony/Muscle cars to be the domain of entrants within E/SP. You could get into models/years/special options, etc, but the "Street Prepared" category is, basically, a class/category that allows bolt-on mods, update/backdate, and without internal engine modifications. I've built my car around that set of rules... ran that class since its inception back in ~1985 to current... very satisfied with the competition and concept of the E/SP class/category.... may, possibly, still someday get back active into it (I observe the local current events, as well as the SCCA national-level competition/entrants).

Now... I'm considering another club here in the midwest (WIS/IL/IN/MI) (www.mcscc.org) featuring "hi-speed" road course solo/autocross competition.. (and their rules are different than the SCCA Solo rules, and car classifications of types/models/years, etc, that I've been accustomed to)... based upon "points per modification".. which, quite honestly, I feel is too arbitrarily assessed.... I've tried, to a small extent, in getting that system changed ... like world war 3 breaking out... oh well... maybe I'll join them rather than fight them... and it's a well run series with good social gatherings, etc. "If ya wanta play the game.. ya gotta play by the rules.."
