Hmmm,
There is always a danger with this type of event that people will make it overly competitive. Everyone who drove their car from the track, and leant something on the day was a winner. The only loosers are those who think it's competitive.
I'll tell you now, when I go out there I'll be driving fairly close to how I drive on the road, so I don't kill tyres, mechanicals, or anything else

If that puts me at the front, or right at the back, then so be it.
The clubMINI committee has talked about arranging a track day with proper driver instruction in the near future. I think spending a little bit of money attending this makes a lot more sense then throwing money at suspension. You will also be a safer driver on the road.
The MINI is an exceptionally well handling car right out of the box, so unless you're chasing that ultimate lap time, it's a waste of money. You are effectively paying for your car's suspension twice !!

Let me know when you do the upgrades, and I'll hang around the bin out the back, and keep the parts for when my suspension wears out in 10 years time
Having said that, if you really want to throw money at the problem, then it can be done. I suggest you do a search in the Aussie forum for "peak" (as in peak performance) who have done a number of upgrades in Sydney. Also have a look in the performance and tuning forum, it's full of that stuff. I would not take my car anywhere else other than Fulcrum suspension at Morooka for this type of work.
So, in summary, if you really think beating other fellow mini owners is your thing, then you could probably spend 10k on a works kit, then another 10k on suspension on wheels and tyres.
Unfortunately, after doing all this there is a very distinct possibility that someone who can really steer might turn up in a stock MINI and whip you
I might be the wrong person to talk to, as I have a baby coming in 2 months, and just spent my works kit on rennovation yesterday, so I seem to have a different value on cash at the moment
Just remember, everyone who drives away from a track day with nothing damaged, and having learnt something is a winner.
