Waiting for my 17" wheels, hopefully it'll solve the problem. (Or maybe I do need the rear anti-roll bar afterall..)
This is actually an indication of good balance. You may wanna more grip but balance is good.
Which tires do you have? still stockers? What pressure front/rear? have you tried different higher/lower? BTW there are some sticky tires in 15", you don't have to go to 17" just for that.
How is your alignment? have you had it checked? lowering may change toe-in on McPherson. Before you start anything make sure your alignment is good. For best fuel economy you want front toe-in as close to 0. On Prissy I have ran 3/16" toe out, and while it was scary good in turns (it was actually bad b/c it used all 100% of the grip in turns and then loose w/o any warning), the MPG wasn't the best. 0 toe-in on negative camber front is good for economy and feel.
Then make sure that you got the right tires (it doesn't make sense to adjust suspension to 0.8g tires if you will be running 1g tires in autoX), But if you will be running both then it makes sense to find settings which will work for both.
Try this test: set up the cone wave course (or imagine if you don't have cones) and see if car understeers. If it does most likely it will benefit from negative camber. I have not seen the camber kit listed for Mirage, but I think it has 14mm bolts , so the 14mm +-1.75 kit should fit. You will not have to go crazy with negative camber, 0.5deg is a big change. With 1.75 kit I would do it roughly in 1/3 increments (which is 30, 45 and 90 deg from top) and see which one works the best on cone wave. Also neg camber kit on McPherson adds toe-in. I will have to look how much but on other cars you'll look roughly 2 1/3 turn on -1.75 camber to keep the baseline alignment, give or take.
Now if you find that you needed more negative camber in front for slalom it could unbalance car and make it oversteer in turns. Then you will have 2 options either to take sway bar off or shim rear to get balance back. Drifters are setting rear to 0 or even positive camber, but I cannot comment on this. FWD slides are much harder to control, RWD is better to learn on. On FWD hand brake is your friend.
Disclaimer: anything above is a pure speculation; not a recommendation of any sort. Use or not use it at your own risk.
EDIT: almost forgot; when you get the initial alignment print out do not be alarmed that left side has ~0.5deg less camber than right. This is for US, but since you guys drive on wrong side it would be opposite. This is to correct for road crown pull.
