STOCKS: Chassis Software Takes Trial and Error Out of Race Care Setup
26 September 2000
ORMOND BEACH, Fla. (Sept. 25, 2000) -- Most racers set up their car the old fashioned way -- by trial and error. Put some wedge in, take some spring out and run a few laps. Didn't work? Then keep repeating this process of adjustments until the driver finds something he likes. But this is the year 2000 and the age of technology, so shouldn't there be a more effective way to determine the car setup? Bob Bolles, president of Chassis R&D, has developed an advanced way to handle the situation, yet one so easy any crew member can use it. Using his patented Chassis R&D software, race teams can quickly and efficiently determine the best setup before heading to the track. The Chassis R&D software is easy to use and features a simple graphical interface. All the user needs to do is input several measurements for different points on the car then allow the software to calculate the best setup. The program automatically takes into account the complex formulas and geometry needed. Teams will not only save a considerable amount of time by using the Chassis R&D software, but money as well. The unique thing about the Chassis R&D software is that it has been proven to work on stock cars regardless of the series or track. In fact, Bolles has engineered the setup for hundreds of teams running on pavement and dirt, from local track weekend warriors right through the NASCAR Winston Cup Series. The common denominator is that teams at all levels have gone on to victory lane and proven the Chassis R&D software is more than worth the $399 retail price point. So how does Bolles explain the fact that his program works so well for all levels of stock cars on pavement or dirt? "The basic principle is balancing the setup of the chassis so that each end of the car will desire to do the same thing when cornering. This is the basis of the method. This is what every race car wants," Bolles explained. "The surface medium, be it dirt or pavement, merely controls the amount of cornering force but the desired results are the same. The principle, when applied correctly, makes all four tires work to their maximum capability." The Chassis R&D software is designed to run on any computer using Microsoft Windows 95, 98, NT or higher. There are two programs available; the first is the Chassis Setup Software that helps the race car obtain maximum performance and make all four tires work in synch. Also available is the Chassis Geometry Software. This roll center geometry program will help the team to quickly and easily redesign a chassis, recalculate chassis coordinates, change arm angles, arm lengths, and simulate dive and roll.
