What do you mean by Touring car racing?

The Touring car racing is a common term for numerous distinct automobile racing competitions in heavily-modified street cars. It is particularly popular in Britain, Germany, Scandinavia, and in the Australia.

What and all constitute a touring car?

While rules differ from country to country, the majority series need that the competitors start with a standard body shell, but almost every other component is acceptable to be heavily modified for racing, together with engines, suspension, brakes, wheels and the tires. The Wings are generally added to the front and rear of the cars. The Regulations are generally designed to limit costs by banning some of the more exotic technologies available (for example, many series insist on a "control tire" that all competitors must use) and keep the racing close (at times by a "lead trophy" where winning a race requires the winner's car to be heavier for following races). In this, it shares a number of similarities with the American NASCAR series, but raced completely on road courses and street circuits rather than the American series' mainly oval tracks.
