Pirtek Diamond Sprint Car Series schedule, rules and more!

Hibbing, MN 5/13/26 by DarinShort.com. A very wet and cool start to springtime in the arrowhead region of northeastern Minnesota is delaying the start of the PIRTEK Diamond Sprint Car Series resulting in a reshuffle of the schedule. The Diamond portion of the Memorial Day events scheduled at The Grand Rapids Speedway and Hibbing Speedway have been moved to this summer – when more suitable weather and predictable track conditions should prevail.

The biproduct of this change has also created something new: The PIRTEK Diamond Sprint Car Series Northwoods Speedweek!

The Hibbing Speedway date has been moved to Wednesday, August 5th, while The Grand Rapids Speedway event will be held Thursday, August 6th. Those two events now piggyback existing Gondik Law Speedway (August 7th) and ABC Raceway (August 8th) dates, thus creating the Diamond Sprint Car Series Northwoods Speedweek!

All four events will consist of the winged division of the Diamond Sprint Car Series, while the accompanying nonwinged (traditional) division will be UMSS Renegades series.

The Diamond Sprint Car Series features some of the best sprint car teams in the upper Midwest, and they will be competing in complete racing programs of heat races and features each night.

The series also invites racing fans to arrive early each night to take in Fan Fest (it’s free). This will allow fans to meet the drivers, check out team merchandise and get an up close and personal look at the cars they will see racing that night – not to mention great opportunities for selfies and pictures with the drivers!

Complete details of each nightly event as well as Fan Fest will be posted as Northwoods Speedweek draws nearer.

The Diamond Sprint Car Series features many of the top winged and traditional (non-winged) sprint car racing teams in the upper Midwest, and drivers are competing this season for a diamond championship ring in each division. The top series points winner will take home the coveted championship prize.

The 2026 Diamond Sprint Car Series also features a new ‘anthem’ titled ‘Diamonds in the Dirt’ written and produced by DarinShort.com. This song will be played to the crowd at each Series event this season, just prior to the cars coming out on the speedway, in an effort to get them fired up for the event to come.

Diamond Sprint Car Series Unveiled for Upper Midwest Teams, Tracks & Fans!

Grand Rapids, MN (12/20/25) by DarinShort.com. 2026 will mark a fresh look and excitement level for fans, teams and tracks in the Upper Midwest, as the new Pirtek Diamond Sprint Car Series rebranding schedule and rules are now available for viewing. Click www.DiamondSprintCarSeries.com to check it all out.

And you know the expression: “put your money where your mouth is?” In that same vein, the Diamond Sprint Car Series puts its series championship winner where its name is – in the form of a diamond championship ring!

That’s right, at the conclusion of the series points season, the top driver in points will receive a custom-made diamond ring to commemorate their accomplishment.

Drivers will preregister for each event, which will allow time for the series and the track to pre-publicize to fans who they can expect to see competing on race night. This simple step will help generate fan buzz as well. Those preregistered drivers will also receive increased payback for their support come race night. Details on this driver procedure will be posted prior to each event.

In addition to the www.DiamondSprintCarSeries.com domain name, you can also click www.DiamondSprints.com as an alternate web address – for those who prefer to type in less characters...and it will take you to the same series homepage.

If you are on Facebook, you can click www.facebook.com/DiamondSprintCarSeries to get the latest series news and interact with others on the page.

This series offers a place for experienced sprint car racers to ‘graduate to’ and gives us, as a series, the ability to keep our weekly racing affordable and fun for all participants involved.

Detailed purse structure and preregistration procedures will be posted in the weeks to come.
