General Rules – 1 change below
1. only difference is that all tires may be used in all classes, except that foam tires are still not allowed
o “All tires, except foam, can be used, in all classes.”
Class Rules – 3 changes below
1. Super Touring and Rally has been changed as follows
o Rule requiring cars to be 4-seater or 2+2 has been repealed
o Rule now reads – “Cars must be sedans and rally car based models (e.g. DTM, BTCC, ETCC, WTCC,WRC, SCCA Pro Rally and similar cars) “
2. Indy Car Class has been voted out
Explanation: Cars for this class are not currently very readily available and where they are, they are not the inexpensive cars they once were. Also spare parts seem unavailable so major repairs or replacement of parts is not practical.
3. Classic Sports Racers has been changed to two separate classes as follows:
3a Classic Sports Racers
- “Cars must be Fly, Monogram, GB Track or Carrera models of Can-Am sports racers (not production based) from 1966-1974.
- No magnets allowed
- You may replace rear wheels with plastic press-on (only) wheels”
Explanation: This class is for the older and less advanced Can Am cars that used to dominate Classic Sports Racers before SlotIt, Sloter and NSR cars were introduced. Most, if not all, club members already have one of these cars. This class does not allow the advanced cars such as SlotIt, Sloter or NSR and gives the older cars a class of their own.
3b A new class, Advanced Sports Racers has been created.
- “Cars must be models of Le Mans, Interserie or Can-Am sports racers (not production based) from 1966-1976
- No magnets allowed
- Motor must either be stock or Scalex black stripe may be substituted
- Axle bushings, axles, gears and wheels may be changed with Fly, Monogram, GB Track, or Carrera cars”
Explanation: It is for any manufacturer and so it does allow the advanced cars such as SlotIt, Sloter or NSR to be raced. People can race their advanced cars, race their stock Classic Sport Racers if they wish or choose to race the modified Fly, Monogram, GB Track or Carerra cars from last season’s Classic Sports Racer class.
Please remember that one of the most important rules in I.M.A.R. is
OVERALL GOVERNING RULE -
IF IT DOES NOT SAY YOU CAN, THEN YOU CAN’T!
To be absolutely clear - If you want to make a change or modification to a car that is not specifically mentioned as allowed in the rules, then it is not legal.
