• If you arrive at the last moment and there are issues with your car, and you cannot fix it before the start of the race, unfortunately, you will not be able to qualify for the race. Please come early to avoid this situation.
• After final approval, cars will not be re-inspected unless the car is damaged in handling or in a race and will be overseen by a leader.

Dimensional Information:

For this race, if it fits the track, you can run it.  If you follow this drawing, your car will fit. 
However, if you would like to push it, the following dimensions are absolute values;

Max overall with = 2.9"
Max overall Height = 5" (different than the image below, 5" is the max)
Max Length = Depends on wheel placement 7" is safe but longer if wheels are "stock."
Minimal wheel clearance spacing 1.1" (inside face to inside face to clear center guide rail)
Minimal bottom clearance = .13 +/- .02"
 

If you comply with the "normal" dimensions, you will be OK with this.  The only size regulations we are imposing are max width,  height, and length to ensure it fits on the track..
