We want this to be the number one sled sport in the future and thats why we want all of the racers to show upp with nice beautyful builds and nice looking grafiks on there sleds. We dont want this to looks like "junkyard racing" sport.

Safety / for all classes:
# Working teather/kill swift.
# Taillight. Min 21watt. A good thing is to mount battery lights so even if the sled stops drivers can see the sled. 
# Working breaks.
# Look over front suspension one more time. Try to minimise clearance and movements before entering a race.
Bolts get worned so do uniballs, bushing, steering arms and axles.
# Tunnel should have plate in back so nobody get hurt from the studs and the track.
# In the pit and paddock we use teather/kill swift and when we warm sleds up we use a covered warmup stand that is connekted to tunnel. 

 

Drivers safety gear:
Approved helmet. That cover eyes and teeth. No vintage helmets.
#No opened helmets alloved. 
#Back and front chest protection. 
#Neck breace. Is not a rule but we want you to have that to minimize.
#Shoulder and knee and armbow protection. 
# Think that ice is hard. # Sleed with studs will chew you up and carbide will slice you apport so use good safety gears.
# Its youre life and we all want to you to stay safe out there. 
# Its better you have to much safety eqiupment than hurt youre self.
# Before you become a racers or you show up on raceday you must have had the apportunity to test youre sled and be well preppered and have a lots of practice sessions before you enter a competition. 

Use enviroment track underneeth in pit area.
Clean youre pit area either you practice or you race ! 

Oil or other kem producs is not ok to spill out in youre pit area or on the track. 

Be cool build fast good looking sleds but stay safe and look out for eachother and have fun doing this !!!
