I am quite new to this forum, and this is a bit of an old topic, but thought I would chime in. Chumpcar World Series (CCWS, or just Chumpcar), is the biggest bang for your buck in motorsports. Chump is a spin off of LeMons, but with some important twists. LeMons is more of a circus with silly black flag punishments like being taped to your competitor and being forced to walk around the pits for 10 minutes or so. Chump has none of this nonsense, it is serious racing. There will be over 60 races in 2013 throughout USA, Canada, and Mexico. So chances are, there is a race near you (or at least within a reasonable tow)
The basic premise of the rules is simple. $500 crap can racing. There is a list of "pre-approved" cars, but if you want to run a car not on the list, you have to prove you can buy 10 examples of your car, running and driving for an average of $500 or less. Of course you have to add safety equipment like roll cage, fire suppression, etc., and this does not count towards the $500 threshold. Tires are DOT rated tires with a tread-wear rating of 190 or greater. Brakes are limited by a 2X rule. For example, if you can buy a stock rotor for $100, you are allowed to spend up to $200 for a rotor. This same formula holds true for calipers, master cylinders, etc. Brake pads are open.
I raced with a couple of buddies last year, and had so much fun, I am building a car of my own this winter. Just about everything has been raced in Chump. Mustangs, Camaro's, lots of Honda's, BMW 3-series. I have also seen everything from a Peugeot sedan, to a Rover V8. I ran an old Datsun Z car with my buddies last year, and that is what I am building for myself this winter. Reliability, and fuel economy are important considerations. Even at a modest consumption rate of 8 gallons per hour in the old Z, gas adds up!
Race formats are generally road course, but a few on Ovals. These are ENDURANCE races. Length varies from 7 hours, up to the 36 hour race planned for my home track here in Spokane, WA July 5-7. Most teams have 4, or more drivers. The longer races you are required to have at least 4. This is wheel to wheel, pass and be passed, run the piss out of it racing, and it is a kick in the ass. I would recommend it to anyone interested in serious, budget oriented racing. Even in one of the "shorter" formats of 8 hours, each driver in a 4 driver team gets 2 hours of track time. And this is not just a track day putting down hot laps. This is RACING. Check it out! www.chumpcar.com
