Frequently Asked Questions

What is “autocross”
Autocross is a low-cost grassroots motorsport discipline that allows almost anyone to enjoy the thrill of automotive competition in a safe, controlled, and legal environment.
An Autoslalom event consists of competitors driving through a ‘race course’ laid out using pylons on a large parking lot or other paved surface. Because the vehicles race independently of each other, at no time can there be contact with another competitor, thus reducing the risks considerably, and allowing the drivers to concentrate on threshold braking and precision cornering. Each run is electronically timed, and the fastest driver in each class is the winner.

How do I sign up for an event?
Registration for every event is ONLINE ONLY on Registration closes 8pm the night before an event, so register early! Event registration links are usually done a few weeks ahead of an event, so if you don’t see your event posted, come back and check closer to the event.

Event pricing:
$50 per entrant (member price)
$65 per entrant (non-member price)

Hey! Is my helmet legal to race with?
Believe it or not, you can’t just show up with any ol’ helmet and race. Helmets must be DOT AND SNELL approved, and not expired. You’ll have to check the tag located on the inside of your helmet. Below is a list of accepted helmets (2021)

What is P.A.X.??
PAX (or Professional Autocross Index) is a pretty much universally accepted form of autocross classing. It “evens out” the playing field, by adding a handicap to slower vehicles to create a competitive factored time when compared to faster cars. Every year, the PAX factors per class are updated. You can find 2022 PAX factors here.

What’s the membership for?
If you are planning on attending a few events in a season, a membership will actually save you money! Members save $10 off admission per event. Members also gain access to the WOSCA Christmas Party and Daytona 500 Party. Significant discounts on tires and wheel products is offered to members at Ted’s Tire, the official tire sponsor of WOSCA. Plus you know you’re doing your part in continuing Grassroots Motorsports!

What else do you do?
While primarily autocross, other events are also held. There is a yearly “WOSCA Drag Day” event usually held every spring. The offseason usually hosts a go-karting day and a sim racing series. Check out the events page for updates. In person events include the WOSCA Christmas Party, and Daytona 500 Party.

Your Car

What cars can I race?
Almost any driver can participate in almost any car, no matter how old, the make, the model, or the modifications that have been done to the vehicle. As long as the car meets certain safety standards (i.e. not dropping fluids, secured battery, wider than it is tall), there should be a class for your car.

Each vehicle is classed and handicapped based on several factors. For example, a Honda S2000 is not in the same class as a Toyota Camry. Modifications will also place vehicles in a higher class with adjusted PAX values.

Are mods allowed?
Absolutely! Though, you will likely be put into a different class, and competing with a different handicap factor. Usually you can get away with good tires and shocks, and stay in the stock class. Engine mods start bumping you into different classes, depending on how extensive your mods are.

The best “mod” you can do to your car is good tires! With autocross courses being fairly tight, you’ll be relying on traction more than sheer horsepower.

How do I class my car?
SCCA® Solo® has many categories divided into classes for vehicles.

Stock – 200TW minimum tires and maaaybe some upgraded shocks.

Street Touring – common bolt-on modifications. Things like cold-air intakes, headers, lowering springs, etc.

Street Prepared – More “bolt-on” mods.

Street Modified – Engine swaps (as long as the engine is made by the same manufacturer as the car), additional turbo/superchargers, camshaft upgrades, and any suspension upgrades as long as it uses the factory attachment points.

Prepared – Generally for non-streetable cars. If it goes like stink, but still looks like a “street” car, it goes here!

Modified – Special built competition vehicles and most of them resemble an open-wheel Indy car or a closed-wheel LeMans sports racer. Basically, if you don’t fit in anything above, you go here!

How do I prep my car?

The Race (Autocross, specifically)

Where is the venue?
This seasons primary venue is the Centralia Airport, in Centralia, Ontario. The gate entrance is located at 403 Canada Ave, Centralia, ON. Look for the WOSCA banner! Gates are open between 8:00am and 9:30am. Driver’s meeting is mandatory and starts at 9:30am. Racing begins after.

What do I bring?
– Your car, legal helmet
– Tire pump, pressure gauge
– Plate covers, tools
– Numbers (either purpose built or tape/shoe polish)
– Sunscreen, sunglasses
– Rain gear, umbrella
– Bathrooms are provided on-site, but unfortunately there are no food or drink amenities available, so bring water and a lunch!

What do I do once I get there?
First thing first, check in at the registration tent! Then find a spot in the pit and unpack/set up your car. Once that is finished, your best bet is to walk the track, as many times as you can! Currently there is no official course walk so it’s up to you to show up early and learn the track before the event. Then when the driver’s meeting is called, attend the driver’s meeting and then it’s race time!

What’s the plan after driver’s meeting?
You will get your group number and marshal station number upon checking in at the registration tent. If you are racing first, then hop in your car and line up in the starting grid. Order does not matter, just find a spot you like. You will be called up when it’s your turn to race. If you are marshalling first, then grab your safety vest, check in at the timing tent, and head out to your position.

How do I marshal?
You are the eyes and ears of the track! Marshals report the cones hit and cars driving off course. If you see a car driving off the racing course, you will radio in an “off-course” to the timing tent. If a car hits a cone, you will have to RUN and place the cone back in place, then radio in “one cone” to the timing tent.
You are also in charge of the safety of the event. If you see anything wrong (eg. fluid dripping from cars, outsiders entering the track, marshals ahead of the next car still cleaning up, a car heading the complete wrong way) You will red flag all cars in your area until the issue is resolved. We would rather 1000 false red flags than one preventable injury!

How do I race?
This is where the fun is! When it’s your turn to be called up, you will line up at the starting line, then when the starting marshal lets you go, you will be let loose on the course to put down the quickest time you can. Cars compete one at a time and are compared using the quickest time out of the day’s runs. You will navigate the course laid out without hitting any cones, then come to a complete stop in the stop-box for the run to be counted. Usually there are 3-4 runs in the morning heat, then another 3-4 runs in the afternoon.
