Classic Instruments made its mark with high quality gauges with retro-inspired designs, and street rodders and custom folks ate them up. Classic Instruments also makes gauges that are ideal for street performance, racing, and off-road activity. The Performance Series gauges pack a lot of technology that delivers precise and reliable readings, including rugged microprocessor-controlled air core movement, a full-sweep needle (most gauges), push-button calibration, integral warning lights that illuminate the entire gauge when activated at set points you choose, and outputs for additional warning indicator lights. The gauges have an analog 0.5- to 4.5-volt output for data logging systems. You can switch between warm white or cool white LED background lighting. Pictured here is the velocity series, with your choice of black or white face with black or polished bezel. For more information, call 800-230-3030 or visit www.summitracing.com.
