Alternates:
If there are more than 32 cars qualifying for the 32-car field, we will start inserting alternates (To replace broken qualified cars) starting at spot 33 and so on... If you are an alternate, and a spot opens up, you will be inserted in the 1st available position before the drivers meeting on Sunday morning. This will give the qualified cars overnight to get the cars repaired.

SCALES:
After each qualifying and elimination pass, all cars must stop and weigh at the track scales. If you lose in eliminations, and your opponent fails to make weight you will be reinstated into the eliminations only if you made minimum weight requirements. If both cars failed to make minimum weight, both cars will be disqualified. It is the driver's responsibility to verify with each track scale, the weight of his/her car prior to each race day. There will 5lb error factor allowed.

All XDR/TT-5 entries are allowed to tow to staging lanes and to the track scales with a golf cart or other similar small tow vehicle. All carts will be subject to search by a SCSN Official at any time.
