It's not just the cars - it's the people!

IROC Series

Inter-Regional Race of Champions

is a pompous name for a very fun series of events. This series – the longest running inter-regional event in PCA – consists of three autocross events we run with our friends from the Motorstadt and Michiana regions.

These events help you learn how to properly maneuver your car around a course of pylons in a parking lot. Instructors are available and we always welcome and encourage new drivers! 

Our friend and BMW racer Brad Pines has provided some great suggestions for those of you considering autocrossing. Check it out on his blog.

You run against a clock and there is only one driver on the course at a time – so it is as safe as you make it. This is a wonderful opportunity to better learn the limits of your car and your own driving skills.

Every IROC event starts out with an Autocross Driving School where you will be assigned an Instructor to help you learn the ins and outs of autocrossing.

This is the 46th year of the ongoing competition; make plans to attend all three events to improve your standing and help your region bring home the coveted “Bent Pylon” trophy!

All makes and models of cars/ trucks/ SUVs are welcome to participate, as long as they pass a brief safety inspection at the track.  Multi-driver cars are welcome, although NO passenger / spectators are allowed on course during the event. We do welcome 16 and 17-year-old drivers; however, they must be relatives of a PCA member. Drivers under 18 must have a valid driver’s license and have a parent / legal guardian available to grant permission to participate.   NO previous autocross or track experience is required!   If needed, you will be provided an instructor until you are comfortable on the course.

All convertibles may participate in these events with the top closed. All open cars must have either a roll bar, cage, or extender using the famous “broomstick rule.”

Registration and tech inspections usually begin about 9:00 am.

There is a Driver’s Meeting/ Track Walk around 10:30 and we start running any novices at about 11:00 am.

Once we start the timed events, you will get five or six timed runs.

!Saturday, June 26, 2021 – IROC I – Motor-Stadt Region – MSR – @ Corrigan Oil Speedway (Mason, Michigan).  The track is ten minutes south of Lansing, or one mile north of the US-127 and Mason interchange on Cedar Street.  Motor-Stadt does a great job of converting an oval track into a fun autocross course by creative use of the crossover pavement. Get driving directions here. Also note there will be a practice session on May 18. Track opens at 8:00 am, tech inspection runs from 9:00 until 9:30, and then there will be a driver’s meeting. Track fee is $30.00.

Saturday, July 31, 2021 – IROC II – Western Michigan Region – WMR Kentwood Community Church, 1200 60th Street SE, Kentwood, MI 49508
8:30 am – 3:00 pm. Registration begins at 9:00, drivers’ meeting (rules and instructions) at 10:30 am, and timed individual track runs immediately follow at 11:00.  Lunch on your own at nearby establishments after the first set of runs.  Autocross resumes following lunch.  Cost for the day is $30 per driver.  You can usually expect at least 6 timed runs for the day.  Snell helmets with a 2005, 2010 or 2015 sticker, type K, M or SA are required and you’ll be asked to sign an insurance waiver.  Come on out and learn how your car handles on a closed course in a safe environment at moderate speeds.  All skill levels are welcome, from novice to expert.

Saturday, October 10, 2021 – IROC III – Michiana Region – MIR – @ The Tire Rack, 7101 Vorden Parkway, South Bend, IN. This is the same track that The Tire Rack uses to test and compare the many “go fast” tires they sell. It is a great venue!


We welcome you and encourage you to try autocrossing!  It’s a cheap (around $30 or so per driver), fun, and educational experience.  If you have any questions, please contact Michael Betz.
