AWD Turbo Parts and Performance

Downtown LA Motors Street Race – September 5-7 1998

The  PRO Racing Series features late model production based sports cars specially modified for racing. Competitors race in one of five class structures based on the performance potential of the cars. Makes and models in the series are Porsche, Ferrari, Acura NSX. Ford Mustang, Corvette, Dodge Viper, BMW, and more. Tops speed of the cars can reach over 175mph on the faster tracks. PRO Racing Series accepts only established race drivers. There is no room for the novice here.

Qualifying sprints on Saturday. On Sunday the PRO Racing Series will see its diverse field of sports cars engage in a one-hour “mini” enduro. As a result of mandatory fuel stops for all drivers, pit action and lead changes will abound. You’ll never know who will win till the checkered flag drops and the Ford L.A. Street Race double s-turns on the way to the finish line.

The PRO Racing series includes race events in such diverse places as Tijuana Mexico, Las Vegas, Laguna Seca, Willow Springs, and of course, the LA Street Race.


We had the opportunity to race with PRO Racing Group on a road course laid out around the Sports Arena in Exposition Park. Our 1992 GST is classified in the P4 class. The 1.1 mile course runs through part of the parking lot and out onto Figueroa St. The main event for the weekend was a 125-mile NASCAR Featherlite Southwest Tour race

This was Rob’s  first race in the RRE GST. Saturday we had a lot of problems with overheating the brakes. We are running the AWD dual piston calipers. We had run the car mostly at Willow Springs on the big track and braking had never been an issue there. Our Porterfield R4 compound pads stopped well enough but they are crumbling from the excessive heat. The course is made up of short straights and sharp turns. There is nowhere for the brakes to cool off.

On race day they did a cool Le Mans style start. As you can imagine it was pretty much pandemonium. The drivers all have their cars lined backed up to the edge of the track at a 45 degree angle. Motor off. When the green flag drops you start the motor and get going as fast as you can. I dont know why it takes big burly Porsches so long to get up and going but Rob fired up and jumped out in front of a bunch of them. They eventually got back by but the photo of him leading all those cars on the first lap was priceless!

Sunday the race was nothing but disaster. Since the PRO Racing group we run with are second fiddle to the Nascar race, we just get the mushroom treatment. Out practice times get cut to start with. Then the NASCAR race turns into a demolition derby on the short tight course. It is pretty much run under a constant yellow flag. It runs late and we are starting our race almost in the dark.

We changed out the calipers and pads overnight, added some better fluid and rigged up some ducting. Sunday they change the start to where you have the motor already running. Green flag and go. Then they decide to call the race short since their fire permit times out. Some of the drivers are pitting, some are still out and they just call the race. We have no idea how we did,

The mandatory pit stop really did us in. We came to a stop in the pits and the calipers burst into flames. The seals pretty much melted right out and the fluid caught fire on the red hot rotors. There just wasn’t enough track to do any kind of cool down lap and stay competitive with the brake setup we had.

We learned a ton from this race. It was a totally different experience racing in front of real people instead of rabbits and coyotes in the desert.
