Hey,

FWD falls into the Class 1. There are 4 Classes. Class one, which I already explained, class 2 which is rear wheel drive, class 3 is AWD, and class 4 is AWD with a turbo or supercharger.

As far as information goes for setting up your rally car for a race, it depends on what kind of races you want to enter. For the rallycross put on by MLRC, you just need a road worthy vehicle really. All the rules and regulations can be found at http://www.mlrc.ca/rallycross/rules.html

For other races such as the Tall Pines Rally, and other ones, there will be different requirements not only for your car, but for yourself in some cases, such as having to have competed in other races, or having specific equipment such as a Hans device.

Anyways, hope that helped out a bit.

If you are looking at performance rallying, there are a few different classes too. Prod Sport keeps your car pretty much stock with the addition of safety requirements. Gr 2 for N/A 2wd cars, no performance restrictions and Gr 5 - throw a huge honkin unrestricted turbo on your car for this group. There is a fast 240sx looking for some competition in this class!

The big thing is the roll cage. This has to be a properly designed and built cage, not a bolt-in piece-of-crap. That means ripping out or cutting holes in most of the interior. Other than that - racing seats and five point harnesses, fire extinguisher, safety triangles, etc. All the details are in the rules which I provided the links for earlier.

In general for RallyX and TSD rallys any street car will do. For performance rally you need a dedicated event car with a roll cage.
