More than just fast street cars, most of the Superlite series of cars make a great platform for racing, or track days.
The factory built a race SL-C in 2011 to develop the car, and to prove its inherent capability. In the process, they set a lap record at every track they visited, won every NASA race they finished, and won the Super Unlimited National Championship, where it won every Championship weekend qualifying race, started on the pole, and lapped every other class competitor except the 2nd and 3rd place cars.
In the rain.
The parts and setup information developed then, and in subsequent years are available to current SL-C racers as well. And customer racers have done very well with their own SL-Cs as well.
For example, in 2015 alone, customer cars finished 2nd overall in the prestigious 25 Hours of Thunderhill, second only to a Le Mans-spec factory IMSA Audi R8 campaigned by a pro team that normally ran the Audi in the IMSA series. The SL-C was actually faster in the dry, but lacked traction control and the range of tires the Audi had, and couldn't keep up in the rain and damp conditions.
Another customer race SL-C campaigned from Raver Motorsports just lost out on winning the Super Unlimited East Coast Championship in 2015 by a restart problem, and finished second after leading the race. The green car below has lapped the Full Course at Virginia International Raceway (VIR) in 1:48.8s. For those who don't know that track, it's an incredible time, and was done with a relatively mild crate LS engine, on DOT tires, standard size wheels, and a very fast but non-professional driver.
Many other owners track their SL-Cs at track days throughout the country with great success, the SL-C offering a great platform that is fast, stable, and reliable, as well as being less expensive to campaign than other nominally similar choices.
For 2016, Superlite will release the new Aero, a dedicated race car designed to compete in the NASA power-to-weight classes. The Aero is expected to be extremely competitive, based on the optimum power and weight, as well as very good downforce vs drag numbers for great handling. Look for more information and results later in 2016.
Part of the success of the SL-C, and the anticipated success of the Aero is a direct result of the extensive Computational Fluid Dynamics (CFD) modeling that Superlite undertakes under the supervision of experts with experience in NASCAR and Formula 1. Low lap times are much more than a function of power and handling alone: nowadays aerodynamic considerations are a vital part of performance. A well-prepared SL-C or Aero is an "aero car", meaning that it is capable of much higher cornering speeds than can be explained by mechanical grip alone. While the actual numbers are proprietary, with the correct aero settings, the new Aero is actually capable of running upside down based on downforce numbers.
But while Superlite cars have incredible speed, racing is more than that; reliability is also required. That's why every component on the SL-C has been optimized for performance, ease of maintenance, and reliability. These design and manufacturing choices make for a fast and reliable car.
If you have a serious racing bug, the Superlite range of cars may be just what you need to provide relief!
