...IMHO I guess TECH @ "Club" races depends on how SERIOUS that club racing IS.
At small local "Club" racing - IMHO Tech is a waste of time.
Set up some loose guidelines - and encourage everyone to run within those guidelines and don't be too "POLICE" like until the local racing has grown to a decent size turnout.
As the size of the club/turnout grows - set more guidelines with a firmer policy of checking (as needed)
Watch the quality of the "on track" racing - there's not a lot of need to worry about TECHING a car that spends a lot of time KNOCKING down walls, spinning out - and simply inconsistant.
Good racers, especially those who like to run larger races generally don't like to waste their time "Cheating" because that won't help them be fast w/ LEGAL stuff when they go to large events.
Running rules that are TOO Tight at local club races CAN make the atmosphere at those races "Un Fun" and a lot of local club racers race 100% for FUN.
