For Slush 2009, two new SCCA classes Street Touring Roadster (STR) and Street Modified FWD (SMF)
are supported to allow preparation and testing for the 2010 season. Rules from SCCA FasTrack are below.
- Catalytic Converters (add to 14.10.E):
Same as ST, STS allowance.
- Limited Slip Differentials (add to 14.10.K):
Aftermarkets units allowed per STX/STU rules.
NOTE, per the STAC: Classing for STR will not be formula based, but will utilize a list of eligible vehicles. Cars *not* on this list
are not eligible. However, as in all subjective classing, cars may be petitioned by the membership for inclusion and will be
reviewed on a case by case basis.
Street Modified FWD
- SMF would encompass ALL FWD cars under the current SM weight formula: 1550 lbs + 125 lbs/liter
- All SM rules will apply, with the following exceptions:
Cars running in SMF using tires with a nominal width of 275 or less will
NOT receive the weight break as stated in SM.
FWD vehicles originally classed in SSM (formerly known as SM2) add 100 lbs
to min weights.
SCCA Renamed Classes For 2009, SCCA has changed the names and class identifiers for three popular classes. SFR follows their lead here; Watch out to avoid misclassing your car!
Street Touring (ST) used to be called Street Touring Sport (STS)
Street Touring Sport (STS) used to be called Street Touring Sport 2 (STS2)
Super Street Modified (SSM) used to be called Street Modified 2 (SM2)
Novice Classes
Novice Classes give new participants a chance to compete with others of their own skill level for trophies. Novices may only run on Street Tires, treadwear rating of 140 or more. They are described HERE Avoid confusion of Novice and Street Tire Classes: Novice classes run on Street Tires in the run group of their open classes. Street Tire Classes (see below) run together in their own run groups, and there is no Novice Street Tire class per se... If you run in Street Tire class you compete head to head with open class drivers and there is no Street Tire Novice trophy.
Class Identifiers are the open class with N at the end, such as BSN, CSPN.
Street Tire Classes
-- SFR runs four indexed Street Tire classes (Just as in
2007). These classes are indexed using the SFR
performance indexes for the current year. Stock Street Tire and
Stock Street Tire Ladies allow stock category cars running street tires
to compete; SP/SM Street Tire and SP/SM Street Tire Ladies
allow SP category and SM cars to run on street tires. Must be legal
according to their class rules. Must run tires with treadwear rating of
140 or more.
Class identifier for Stock Street Tire is T1- followed by the open class, like T1-BS or T1-HS Class identifier for SP/SM Street Tire is T2- followed by the open class, like T2-BSP or T2-SM For Ladies Classes, use T1L/T2L, like T1L-BS or T2L-XSP
KARTS
SFR runs the SCCA classes for shifter karts and Junior Driver 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
At each event, classes generally run one run group later
than at the previous event
