I presume that by "rally" you are referring to tarmac rallying as off road rallying requires soft spring rates.
I have used 180lb coilovers on the front and 150lb coilovers on the rear of my Mk1 Escort. My experience has shown that this works very well when used with appropriate adjustable dampers such as adjustable Koni's (which I am using) MCA, Bilsteins, GAZ, DMS, etc etc. Whilst spring rates are very important, the same amount of consideration should be placed upon the dampers. Having the ability to control the rebound and compression of the damper will only enhance the springs performance.

I have 190lb springs in my mk2 2L with kings on the back. It's a road car but I use it for motorkhanas and have taken it to mallala on semi slicks.
 
To me, the springs are stiff enough for the street and the car handles well. The front of the car drops under brakes but not a considerable amount. Also if you are thinking of doing motorkhanas it isnt a bad thing for the front to drop as you hit the handbrake. I would however go harder if the car was predominantly used for the track, the springs are a tad too soft in my opinion when using a really good tyre on a racetrack.

Track work is fun nomatter how fast the car, mine has 63rwkw and I had an absolute ball. There isnt really much that can go wrong if you know the limitations of your engine and keep the car cool and dont over rev it etc.
 
Yea you do, for track days you only need level 2 non speed which is approx $60 a year, same license for motorkhana, khanacross and drifting, not that ive ever done drifting. To get the cams licence all you need to do is be a member of a car club and fill out a form for it.

Troppo, for Mallala you can also buy a day licence which is around $25 without the need to be a member of a club. Good if you just want to go out and give it a trial to see if its for you.
