This event is part of the Triplemania Weekend which also includes the Ohio Diecast Challenge, Battle of the Builders, and Downhill Diecast Drags Championship. If you're entering this race, check out the other races too because a single car may qualify for several events. And if you're entering multiple cars in multiple events, just send them all at once.

Nothing too fancy here, just some good old fashioned racing. Find or build a car and we'll race on a 21-ft Drag Track setup courtesy of the Autobody Specialists shop in Columbus, OH.

The winner will receive a new Redline Derby Axle Alignment Jig and other RLD swag.

For those that want their entry back after the race, return shipping is FREE for this event. But if you don't need to have your car returned, please choose to have it be donated to the weekend event where it will be made available to kids looking for some free cars to enjoy.

This is a stock Drag Track system setup running 21-feet, owned and operated by the Autobody Specialists shop team. Both cars will be released at the same time. The timing tree is not being used, nor are times recorded for this race.

Race format and scoring

This will be a single-elimination tournament. A car will move on in the bracket only when it wins two races in a row. Cars will alternate lanes between each race.

The car that wins the final race will be declared the winner. Additional races will be held to determine the other Top 4 finishers. Race host has final decision in all races.

Bracket seeding will be random with byes used as necessary depending on the total number of entries.

The Drag Track starting gate is notorious for not dropping 100% of the time. Every effort will be made to get your car to release fairly for both lanes. If for whatever reason your car will not release on a specific lane after several attempts, the time for the other lane will be logged.


Cars are given a grace of 1g over the stated weight limit to account for variance in scales.

If a car fails to meet any of the restrictions listed above, the car will not qualify for tournament prizes. Offending cars may still race. Prize will go to the runner-up in the case of penalty car winning.

Cars that fail to run or fit on the track, or that happen to break during racing, will forfeit their matches. Cars that arrive broken will attempt to be repaired before the tournament. Cars that break during the tournament will not be repaired or replaced.

Just a quick update that we've decided that Zoom-In casting mods are not allowed. If you care to enter a Zoom-In as a stock entry, that is fine. 

Sorry for any inconvenience or if you had already started a Zoom-In mod. Thanks for your understanding.
