A few points in driving and modification...
- Upgrading the rear swaybar on the MR2 can make the car more snappy, and less forgiving.
- As covered by many people lifting off mid throttle can cause snap oversteer.
- steering/braking/throttle inputs should be smooth when pushing the vehicle.
- Take your car to either a skidpan day, driver training day or defensive driver course.
- Get wheel alignments done regularily.
- Make sure you have good tyres
- Drive carefully in the rain, one of the most common "lost control of my mr2" stories start with been a bit too quick on the throttle coming out of roundabouts.
- If you own an adub, try avoid making your car overly stiff, as it can make the car very hard to control on rough roads.
- Flogged out steering components and suspension bushes can make for some quirky handling traits.
The most important thing is to get to know your car and how it responds to your driving style in a safe and controlled environment. Skidpans are good for intentionally making your car loose control, so you can familiarise yourself on how the car feels when it lets go. driver training and defensive driving courses are pretty self explanitary.
If you are going to take the car to the track, depending where you are, some tracks are better avoided if you haven't been to the track before, or things you should be mindful of. For victoria...
Winton: Good track to learn on, most things are low speed, minimal things to hit
Sandown: Not the best track to learn your car on, very unforgiving if you get it wrong
Phillip island: Fast track, requires cam's licence.
Calder park: Not too fast, just be careful coming onto the front straight.
