Rear Sway bar helps a lot!
My car felt weird when cornering recently. Today I made a turn at what I thought was a reasonable speed and the rear end swund around on me! It felt totally out of control when turning. I put it up on jackstands and it turns out one of the bolts on the rear sway bar had come out. I put it back in and I will be taking it for a test drive soon. lets hope I can keep it under control! 
Is this how a car without a rear sway bar and with a front bar would handle?

xsboost90 (Dan) installed an S2 rear bar (off of 944Pete's car) and it is much improved.
Many things can make you break free, but I'd bet the missing bolt was your issue. It couldn't have helped things.

My car came without one to. When making a hard turn, it always felts like the rear inside wheel must be coming off the ground due to the body roll. I recently added a 24mm front and 18mm rear bar. The rear feels much more planted through hard corners now.

my 924S went from the whole "No sway bar in the back, 19mm in the front" to a completely different setup when I got ahold of it...Now, it's got a 24 mm Turbo front sway, and a 968 M030 19mm adjustable rear...WOW the difference was great!

Swaybars > Springs. Many misinformed people buy stiff springs for their street cars instead of upgrading the sways. Big mistake. Huge swaybars eliminate a lot of sway, but the cars suspension is still nearly as compliant as stock.
Ever hit a bump with stiff springs through a tight turn on a side of a clif? Probably not; you're still here...
Currently running weltmeister 28mm front on full soft and 18mm rear. Waiting to get a 22 rear bar so i can put them both somewhere closer to full stiff.

How you get your rates kind of depends on how you use your car.

[Removing a rear swaybar would cause more understeer.]
Not normally, the usual "rule of thumb" is stiffening the rear end will give you over steer and stiffening the front will give you understeer. Based on the assumption that the end of the car with softer more compliant suspension will have more grip.
Problem is that car setups are rarely as straight forward as this! But in the case of the 944 a nice stiff rear end makes the car feel good and makes it more predictable.

Remove rear sway=less rear stiffness -> more understeer

thanks for all the replies guys. I am still scared to take hard corners with my car. I have sway bars from an 86 turbo on my car. (I dont know what size those are) Maybe I am just not used to how the car handles with skinny tires on the rear (7") Most of the year I run 9" tires that are heavy and do not break loose.
