I drive carefully and well within control on the street, and so having the traction control and VSC off makes very little difference. I rarely reach the limits of the car on the street because these limits are very high for normal street driving. If I feel a little slip (I have quite a bit of experience with RWD cars) I usually take it as a notice to slow down. So far, when I have reached the limits of this car ON THE TRACK, it has been very controllable with no unusual or unexpected reactions from the car (like snap oversteer), so DON'T PANIC if the tires start to slip a little. Also, the car in stock form on a dry road with good traction does not really have enough power and torque to induce a lot of power oversteer, so this is not a primary concern. [Power oversteer is when you apply enough power and torque to the rear wheels to overcome their grip on the road. This causes the rear end of the car to slide out and around the front end of the car.]
If you are CLOSE TO THE CORRECT SPEED going into a corner (only experience will let you understand what this is), the car will PROBABLY make it through close to the correct line if you keep steering in the direction you want to go even if you loose traction a little bit. Keep in mind that I have approached these limits cautiously correctly, and ON THE TRACK due to my experience. If you throw the car into a corner WAY too fast, nothing will save you including traction control or VSC. If you do end up going WAY TOO FAST into a corner and get into a really wicked skid, do not try to keep steering onto the road. Look for a good exit onto the shoulder or other run-off area where you can safely slow down the car (EASE off the throttle in this case), or just put both feet in (on clutch and hard on the brake) and go along for the ride; in this case you will probably spin, but keep traveling in the general direction you car was going when you locked up all 4 wheels. [You need some experience and probably a school (or 3) to teach you how the scenario in the last sentence could play out and why and which option to choose when; it depends on how fast you are going and in what direction, the road conditions, how fast the car is rotating, what lies ahead, and your skill level

I have a lot of experience with RWD cars and drive with the traction control and VSC off most of the time. Exceptions to this rule are when it is raining (for now as I have not had time to explore the reactions of these tires in the wet yet). I also leave the traction control on if I am tired or fatigued and do not want to concentrate as much on the car's reactions. I would recommend that newbies leave the traction control and VSC on almost all of the time. Put a good set of WINTER tires on the car in the fall if you live in an area that sees snow or ice during the winter. When driving in snow or icy conditions, you may need to turn off the systems to allow wheel spin to get the car going (especially important with AT), but you can usually turn them back on once you do so.
If you are interested in really learning the limits of your car, do some of the following:
Do take the car to a track that has some good personal instruction. Learn how to approach the limits of the car by slowly and controllably approaching the limits. Ask your instructor to help you learn how to drive without the traction control on once you have mastered the basics.
DO NOT race on the street or see how fast you car can go around a curve on the street. That is what tracks are for; learn how to drive on the track and get involved in some clubs that offer frequent track time and you will soon be bored with anything on the street.
If you are lucky enough to see significant snow (or better yet have access to ice roads on a frozen lake), you can cautiously explore the limits and dynamics of rear wheel drive at very low speeds (shut off the traction control and VSC). Make sure the roads, or parking lot you choose are deserted, or better yet, take a school on the snow at a track or on a frozen lake. Be aware that snowbanks (and especially ditches) can still damage cars, so again cautiously approach the limits.
