Attention Pittsburgh’s Pennsylvania Motor Speedway Pro Stock racers, if you would like to share suggested Pro Stock rules with Miley Motor Sports for the 2019 season please email them to contact@ppms.com Subject: Pro Stock RULES INPUT. Please indicate if you are a Pro Stock car owner or driver interested in racing at Pittsburgh’s Pennsylvania Motor Speedway in 2019.

Miley Motor Sports is seriously considering going to RUSH PRO STOCK Series rules for 2019. As you may know Miley Motor Sports brought the first Crate motors to Western PA 20 seasons ago. Although the change is difficult up front, we believe the Crate Motor can ultimately make the Pro Stocks a strong weekly division at PPMS, much like the RUSH Dirt Late Model Series Division. 

Miley Motor Sports goal is to have an in house rules meeting and publish any rules revisions for all weekly divisions no later than year end. Thank you for your support at Pittsburgh’s Pennsylvania Motor Speedway. We welcome your suggestions.

2018 Pro Stock rules:

Pittsburgh’s Pennsylvania Motor Speedway used the PENN/OHIO rules package with open Hoosier tires.

Miley Motor Sports plans on continuing PENN/OHIO PRO STOCK Events at Pittsburgh’s Pennsylvania Motor Speedway regardless of the direction we take on weekly rules. In particular, the Ed Laboon Memorial, and as usual a second event as scheduling permits. 

 

 

 

All RUSH DIVISIONS that race at Pittsburgh’s Pennsylvania Motor Speedway will follow respective RUSH rules packages. RUSH Dirt Late Model Series will race weekly, all other RUSH Series will be brought in as available.

SPRINT CARS will follow Series rules or if non sanctioned will run as 410 Outlaw Sprints with a Hoosier tire rule as in 2018.

Super Late Events will follow visiting series rules.

Young Gun rules will remain the same for 2019.

PENN/OHIO Series will continue to be used for the Ed Laboon event.

PPMS rules for Pro Stocks, Hobby Stocks, and non Young Gun 4 Cylinders are being evaluated with a goal to release all 2019 Pittsburgh’s Pennsylvania Motor Speedway RULES no later than year end 2018.

We value your input by email to contact@ppms.com
