Bodies may be functionally modified with minimal effect external appearance. The following non-comprehensive list of body modifications are allowed: o Excessive external cutting of the body is NOT ALLOWED for weight reduction purposes. The rear bumper may be removed up to 20mm from the ground.
o Wheel wells may be cut forward or backward to accommodate different wheelbase chassis.
o Wheel wells may be cut or chamfered internally for tire clearance.
o Lower portions of the body (including entire molded front splitters/bumpers etc.) may be cut for ground clearance in front, sides or rear.
o Body material may be shaved or thinned internally for weight reduction. Technical inspection officials reserve the right to disqualify any modified body deemed to be too fragile due to excessive material removal.

o Any rear wing that comes with a particular body may be installed regardless of height. Custom wings are permissible, limited to the 45mm from the ground.
The above list is non-comprehensive. The purpose and spirit of the rules is to allow functional performance modifications to the body while preserving the scale appearance and realism. The technical inspector has final authority in the judgment of body modification legality.
If you have modified your body and have questions regarding the legality of the modifications, please submit the body in question to technical inspection PRIOR to racing qualification or main event round. This is in order to prevent any inadvertent disqualifications. The technical inspector will judge the legality of body modifications and photograph the body in its legal state if necessary.
If the body is further modified post-inspection, the modifications may or may not be legal. For the racer's protection, please re-submit the body in question to technical inspection IMMEDIATELY if significant modifications are made.
If the body is damaged, the condition of the body may or may not be legal. For the racer's protection, please submit the body in question to technical inspection IMMEDIATELY if significant damage occurs. If the damaged body is judged illegal, it must be repaired or replaced for the next qualification or main event round. Qualification or main event results during which racing damage occurs on track will be allowed, as long as the body is not judged to be intentionally designed to break away to benefit performance.

Circumstances may require that radio transmitters be held by race officials until the drivers in each heat or final require them to race. The process of impounding radios will be explained to all racers during the driver meeting.

All racers are encouraged to bring their cars to the officials during open practice so that any corrections can be made before the official inspection.
Before each race
Technical inspections will take place before each race. Inspections will be performed by race officials. If the race official determines that the car does not meet the requirements specified in this document the car will be deemed illegal and will not be allowed to race. It will be the responsibility of the driver to ensure that the car meets all requirements and passes inspection before the race begins. In the event that the race official does not catch a violation, the car will still be considered illegal and the racer will be subject to any consequences of running an illegal car.
After each race
Cars and radios from each race must be put on the post-race tech table for any post-race inspection that is required. Drivers that did not finish their race are still subject to this rule. Inspection of cars will start only after the start of the preceding race (for example, inspection for race 2 will start after race 1 has started and is underway). Cars on the post-race tech table will not be released until the end of the following race (for example, cars that ran in race 2 will be released when race 3 is completed).

Certification of the legality of any car is not final until after the post-race inspection.
