^What Norm (nhibbert) said.
We competed in this years Tallpines rally (red Focus) and I distinctly remember my navigator saying to me "wow I'm so glad that we did nav. rally, this stuff would be so much harder to understand without that experience".
So, if you are lucky enough to have a dedicated codriver, get out to as many nav rally events as possible. They're cheap, provide a TON of seat time, and some actually challenge the driver as well.
I'll tell you that running a stage in performance rally and pushing to gain 1sec/km for example, kinda sucks when you get a 1 minute late penalty at the next control due to an error or just not paying attention as it is a 10 sec. penalty added to your time. It's much nicer to keep things clean, and when you want to risk damage/DNF by pushing harder, at least it was worthwhile if you do get through the stage! Mistakes are bound to happen at first, but it's a steep learning curve and it comes quickly.
As was previously mentioned, you tend to meet a LOT of rally people when you do nav rally or rallyx or work a rally, especially workers and organizers (and competitors, I love that in rally you can talk to the celebrities. I remember a nice Friday night chat I had with Ken Block a few years ago regarding shakedown conditions). Thank the workers and organizers when you get the chance, they are amazing people who do amazing things (at their own expense) so we can go play with our toys.
If you alternatively want to jump right into performance rally, you better call your accountant/financial advisor and TELL them what is about to happen, as I
Guarantee they will not ok it haha.
Decide if you want to build or buy. If you want to build:
Print off the CARS rule book (found here:
http://www.carsrally.ca/), read it cover to cover (this will take a few days or a week at leisure), flag the pages you'll need for the build, pick a class (recommended to start in Production or Group 2/5), pick a car, find a clean example of one, have someone weld the cage in, buy all of the safety equipment and whatever mods you want/you can do as per class rules etc. Build the car to the specs, get it approved by the scrutineer and go play.
If you want to buy:
This option is usually cheaper as they tend to come with spare parts, tires, rims etc and you don't take the depreciation hit, ok well not as large as the builder. Also if it was raced recently it might have a legal rollcage, it might also need updates. Make sure you get some quality advice from a scrutineer if you decide to go this route!
A properly built car can last quite a long time and a poorly built car can cause a LOT of problem including random DNFs so choose carefully.
Also be ready to handle the event costs (the build/purchase costs are large and happen once, but the event costs are ongoing), if you can, search out sponsors, they make things a TON easier. Take time to try to get them, more than likely though you'll be on your own for at least the first couple events. Budget an extra 20-30% because this is rally and things happen, lots of them.
Think entry costs, accommodations, gas is a big one (you never bring enough for the racecar at your first national event), tow vehicle, trailer, food at the event, generator (buy/borrow/rent), service crew (a buddy or two), tires, brakes, lights the list goes on.
In conclusion, personally I started with navigational rally, spent 5 years attending Tallpines in some capacity, worked multiple performance events in that time, and spent about a YEAR researching, hanging out in service areas, talking to rally ppl (4*, hot bits, Petey K, Tibor amongst others) and just absorbing everything I could in regards to both building and driving rally cars and cars in general.
In June of 2009 I bought a red Ford Focus for $600 and the rest is history.
