Tires come in many treads, sizes and performance characteristics. Here is a primer on the basic car tire categories and some popular consumer choices. Extreme Performance Summer Hyper-focused on extreme dry grip, but gives up wet traction, comfort and tread life to get it. Not to be driven in near-freezing temperatures, in snow or on ice, or at high speeds in deep standing water, these specially tuned tires combine big-block tread designs with aggressive tread compounds and reinforced...

Crumple Zones
Crumple zones, crush zones, or crash zones, are a structural safety feature used in automobiles, to absorb the kinetic energy from the impact during a collision by controlled deformation. This energy is much greater than is commonly realized. A 4,409 lb. car traveling at 37 mph.,before crashing into a thick concrete wall, is subject to the same impact force as a front-down drop from a height of 47 ft. crashing on to a solid concrete surface. Increasing that speed by 50% to 56 mph. compares...

FeaturedEngine Control Unit (ECU)
An engine control unit (ECU), also commonly called an engine control module (ECM), is the brain of your car. It is the main reason that we are now in the second era of muscle cars, despite restricting emission regulations. The ECU controls a series of actuators on an internal combustion engine to ensure optimal engine performance. It does this by reading values from a multitude of sensors within the engine bay, interpreting the data using multidimensional performance maps (called look-up...

Exhaust Headers
A component of any car or truck engine is an exhaust manifold for each bank of cylinders .In most production engines, the manifold is a cast iron assembly designed to collect the exhaust gas from two or more cylinders into one pipe. Engineers like cast iron because of its heat management properties and its superior longevity over any other type of exhaust outlet design. They also use the least metal, occupy less space and have the lowest production cost. Although these design restrictions...
