Tech, as we tend to call it,
is really a safety inspection to the rules as noted
below. Car classification issues are not the function of
tech. Vehicle classification is the responsibility of
the competitors. A copy of the rule book and some
supplemental listings are available at the event to
assist in determining vehicle classification.
The following items are required checks per the 2006 Solo II rules. A paraphrased summary is contained below for information. The binding language is contained in the rule book, which is the governing source. The actual text can be found beginning on Page 26 of the SCCA National Solo 2006 Rules.
