• Novice Classes --  All entrants in a Novice Class -- say, Novice 1 -- compete for a single set of trophies. Novices run in the same run group as their Open Class. The Novices that run together in a run group will make up a separate Novice Class. 

  As a result we will have 8 Novice Classes.  
  See event information pages for classes in each. 

  Novice classes: see also the Novice rules.

  Stock, Street Prepared, Street Touring, and Street Modified Novices may run street tires only -- treadwear rating of 120 or more.
  Modified and Prepared Class Novices may use any Solo2 legal tire. 

• Street Touring 2 (ST2) --  is new for 2004. Two seat sportscars on street tires.

  NOTE: Section 14 will be the ST rules in the 2004 Rulebook. Sections
  1 thru 10 will define STS. Section 14.11 defines STX by how it varies
  from STS. We follow the same method as STX for defining ST2 as follows:
  14.12 ST2
  A. The ST2 class encompasses different vehicle eligibility limits
  than those specified for STS, and adds a limited number of allowed
  modifications.
  
  1. All STS allowances carry over, including street tires,
  emissions, etc.
  
  2. Vehicles eligible for this class include 2-seat sports cars
  and sports car based 2+2s (e.g. Porsche 912, 944, and 924, Datsun
  240/260/280Z 2+2, Mazda RX-7 2+2, etc) currently classified in CS, ES,
  GS, or HS. Vehicles eligible to compete in STS or STX are not eligible
  for ST2.
  
  3. Only factory limited slip differentials (LSD) are allowed on
  AWD vehicles as defined in section 12.4. For AWD vehicles which did not
  come with any sort of LSD, including center differential or transfer
  case, a single aftermarket LSD may be added. 2WD vehicles may use any
  LSD unit.
  
  4. Additionally Excluded cars: Lotus (all), Triumph TR-8, Renault
  Alpine, Sunbeam Tiger
  FWIW, there are 13 paragraphs that define the additional preparation
  allowances for STX. The above ST2 proposal includes only one.

• Street Touring S (STS) --  is an SCCA National Class
• Street Touring X (STX) -- Same rules as Street Touring S, but for sedans with engines up to 5.0 liters normally aspirated/2.0 liters turbo- or supercharged.  Limited Slip diffs and a few other extras are allowed in STX.  Rules are in the February, 2002 FasTrack News. 
  • STX is a new SCCA Regional supplemental class.
• Street Touring R (STR) --  has been discontinued by SCCA for 2002.  Former STR cars may run SM, OSP, or perhaps DSP, but SFR will not provide an STR class or trophy in 2002.
• Street Modified (SM) --  is an SCCA National Class
• Street Modified 2 (SM2) -- New Street Modified class for 2 seater and lighter cars.  First year in SFR (and SCCA!)
• NOTE: Specific rules for this class are not known to us at this time.  They will be posted as soon as possible.
• KARTS 
• Kart Drivers, please tell Registration you are Karters. 
• Read and become familiar with the SFR Karting rules before the event
Karts will not be allowed to be driven under power through the paddock; they must be pushed either on the ground or on a portable stand
• Street Tire -- Must run tires with treadwear rating of 120 or more.

At each event, classes generally run one run group later than at the previous event
