Philosophy: The ABQ Super Lap time trials are focused towards street cars as an opportunity for people to drive their cars in a fast, safe, competitive environment.
Street Focused Classes: To start out there will be 3 (X, Y, Z) street focused classes based on a combination of vehicle power, weight, and tire size. For these classes tires must be DOT approved and have a tread wear rating of 100 or greater. These cars will be intended to be able to be used on the street, as such they will have functioning lights, windshields, etc, and be able to be registered for street use with the following exceptions:
- Emissions equipment may be modified or removed
- Auxiliary lights need not comply with DOT requirements
- Tires may stick out past fenders
When it comes to whether or not a car is intended to be able to be used on the street, the spirit of the rules is more important than the letter. Eric La’mar, or his designated representative, will be the final decision authority on this and will address any questions or disputes.
Determining Which Street Focused Class a Car is in: We do not have a dyno or scale so there will be an element of the honor system in place when it comes to vehicle weight and power. A good faith estimate of weight and power for a modified car should be provided by the owner/driver of the vehicle. Power is based on crank horsepower, weight is based on curb weight (not GVWR) without the driver. For stock cars, the manufacturer ratings will be used. For estimating power in a modified car, add the amount of additional wheel horsepower from the mods to the factory crank HP rating to get your estimated crank HP. For weight, either weigh the car at a weigh station, or estimate based on similarly modified cars of the same type or subtract the weight difference of any weight reduction mods from the factory curb weight. Again these are good faith estimates, we are not pros racing for big money, so be honest, don’t be “that guy.” Tire size is based on width only, the marked size of the largest tire on the car is the size that will be used for classing. Use the below matrix to determine class:
- Vehicle Weight / Crank HP = Power to weight ratio
- Subtract any points from tire size to the power to weight ratio to determine total classing points
- Use the table at the bottom of the page to determine any points from tire size. Curb weight is on the left in lbs, tire section width is inside the table, and points are across the top
Example: 2001 Honda S2000 with some mods
- Car was weighed at 2700lbs
- Car’s mods typically add between 10 and 15hp
- Car is rated at 240hp stock so power is between 250 and 255
- Car has 255 width tires so gets 1 point
- 10.59 – 1 = 9.59
- Total points = 9.59, so the car is in Class Y
Class X: 14 and up
Class Y: 9.1 – 13.9
Class Z: 9.0 and below
Unlimited: The Unlimited class is intended to give a place for fully built race cars, or extremely modified cars which are not intended for street use, to compete. These cars may use sub 100 tread wear rated tires, or even full racing slicks. Street cars which have sub 100 tread wear tires are automatically bumped to this class. The only restriction in this class is that the car must meet safety requirements for track use.
