Rallying is the X games of Motorsports...They put the entire car thru so much punishment so the products that survive the abuse usually finds its way onto other types of motorsports...The gearboxes are clutchless DOG boxes that are now being used in Drag Racing...These aren't air shifted its an actual Manual Tranny Gear Box with a Sequential Paddle Shifter...These cars boost close upwards around 50psi to keep the torque up...The intake restrictors are so small, if you take your pointer finger and touch your thumb, thats about the size of the intake piping...They replace complete turbocharger/manifold/wastegate assemblies between stages where they are allowed...They swap complete trannies in under 15minutes...The camera you speak of is in the top front corner of the car...Thats whats Known a V-Rally...Virtual Rally...You can track your driver on I believe, www.wrc.com with V-Rally...Its basically a GPS with a Live Video Feed...

On the Safari Rally, they actually take a metal hose and clamp it to the exhaust for when they drive thru the deeper parts of the rivers they pass thru...You can buy these cars and lots of people do...When these cars are used and retired, they are cleaned up and put up for sale so Private Owners can compete in Group A, which is an anything goes class...

Drivers who drive Rally are said to be the best drivers in the world...And that comes from the Formula1 Driver's themselves...
