Class Rules:
***Losi 1/12th NASCAR Stock Car Rules***
-All parts must remain as the manufacturer intended.
Stock electronics only, Spektrum SLT2 radio, Spektrum 2 n 1 esc/receiver, Spektrum SX110 servo, Spektrum SPMX142S30HS 1400mAh battery and Losi 28T 380 motor are the only electronics allowed. A Y-harness is allowed to power a transponder. Any 25mm fan is allowed.
-No added weight, anywhere or of any kind.
-No cutting or grinding the chassis or any of the parts that attach to it for any reason. The top deck/center brace must remain in tack as delivered from the factory. All the screws must be used in the top deck/center brace.
-Stock spur gear and pinion only.
-Losi NASCAR bodies only, any paint scheme is allowed but a racing theme is encouraged. You must have a number on your car.
-The body must be in the stock location and height. No trimming or lighting the body.
-M4 washers may be used on the screws under the front splitter to keep the screws from pulling through the bumper. The screw head must not stick out past the outer part of the splitter.
-Any shock oil may be used. No internal limiters are allowed. The stock 2.5mm bump stop is the only bump stop allowed. There must be 10mm between the bottom of the shock and the eyelet when fully extended and the shock must be able to compress all the way to the 2.5mm bump stop. Original black springs only, no upgrade springs, no cutting the springs.
-Grease may be changed in the differentials but must remain free spinning. Tech for the differentials will be the same as for Tamiya TT. With the car off the ground, spinning a tire must cause a differential action in the opposite tire without spinning the motor over. If you spin a tire by hand and the motor spins, then the differential isn't legal.
Approved upgrades and adjustments:
-Any weight shock oil.
-Gluing the sidewall of the tires.
-After market 25mm fan
-Losi heat sink Part #LOS-1920
-Losi Aluminum servo horn part #LOS-1910

-Ride Height: Minimum 6mm with a droop minimum of 10mm. Droop will be measured by placing the chassis on 10mm blocks and all 4 tires must maintain contact with the surface the blocks are on. This rule is to minimize the number of limiters in the shocks and to maintain suspension movement.
