                                                                                 TENTATIVE RULES                                               

 

    Those racing in Super Late Model class will be allowed to run our present Good Year tire for a faze in period. I will release time when available.

 

 Same applies for Crate class. To receive National points you will have to be UMP Crate legal. Any UMP Crate Legal car will receive 4 extra points, no matter where they finish. Any Late Model with a Legal E-Mod engine, may run in this class. Must use restrictor plate and will go by E-Mod claim and tear down rule.

 

Effective 2009 all engines, tires, etc, will be as per UMP Rules

 

These Crate Rules are new, but I believe they are here to stay and I will do my best to enforce rules

 

Crate and Super Late Models may have to run together until we have enough for two classes. I will try to keep them separate in Heat Races if possible.

 

As far as purse pay goes, when classes are combined , we will use Super Late Model purse and give crate pay for highest pay of either Super or Crate, depending on his finish. Example if the highest racing Crate finished 5th when running in combined class with Super Lates, he would receive $400 – which is 1st place money for a crate. Since the UMP Super Late Models and UMP Pro Late Model classes are new at Spoon for 2008, all drivers will start with zero season points in these two classes.
