STREET TIRE (SK1 & SK2):
(a) Purpose: To encourage drivers who compete in CSCC SOLO events to race
on the same tires they use on the street. (Also referred to as “Street
Stock.”)
(b) Eligibility - SK1 & SK2: Any Stock Class legal car, prepared in accordance
with Para. 13 of the 2003 SCCA National SOLO II Rulebook, with the
exception that all of the tires mounted on the car must have a TREADWEAR
number of 140 or higher molded by the manufacturer on the sidewall.
(c) Indexing: Each car competing in the Street Stock class will be indexed in
accordance with the PAX (performance) index. For the sole purpose of
team championship point calculation, times shall also receive an additional
“Street Tire” index (SK) which is listed in Appendix C.
(d) Separate classes:
1) SK1 consists of SS, AS, BS and FS.
2) SK2 consists of CS, DS, ES, GS and HS.
3) Men and Ladies shall compete in separate classes.
(e) Registration: Each Street Stock competitor shall, in addition to listing SK1
or SK2 in the Class block, shall list the class he/she would normally run in
(e.g. if a competitor normally runs CS, he would write SK2 in the Class
block and CS in the Indexed Class block).
(f) Results: Every Street Stock competitor will have their corrected times
listed, then the PAX index for their car, followed by the best 'indexed' time,
arrived at by multiplying their best corrected time by the PAX index number
for the cars class and also the SK index from Appendix C. [Example
Calculation: (Best Time) X (Class Index) X (Street Tire Index) = Final
Indexed Time]
(g) Trophies: Trophies will be awarded for each event in accordance with Para.

Curt Luther wrote:Jeff's answer makes the most sense. I do believe, at one time, it was ST1 and ST2. When they introduced the STS and STR classes, they might have made a change then to reduce confusion...which in this case caused more...
