The engine block and a piece in the nose that carries the VIN number come from the manufacturer. That's about all that is "stock". Some other pieces, e.g. the Ford differentials used in most cars, come from the manufacturers, so not everything originates in the racing specialty shops.

The tubular space frame chassis and body panels are essentially hand made to fit a series of templates that define the shape of each type of car.

What I don't understand is why they don't continue racing in the rain? Just pit and put on rain tires like Formula One does. That goes for both NASCAR and American open wheel racing -- bunch of wusses.

I don't understand the rain deal either...so they would have to slow down a bit...the speeds would be realative to eachother... would still be exciting.

I'd show an interest in watching NASCAR if it took on a more competative, gladitorial compontent such as sacntioned bumping, ramming, and allowing the drivers to duke it out during race stops......Give it a Road Warrior flavor and I'll be a fan!
