Extreme understeer and front end vibration
Well I was trying to do some donuts in an abandoned parking lot yesterday/today and was displeased to find that I was unable to due to 2 problems. For some reason, the front tires have like no traction at all and tend to break lose before I can bring the rear end around. The second problem, likely related to the first, is that the front end shutters violently when I turn in really tight. I have Eagle GTs and no mods related to suspension/handling, if that matters. It's just like really bad understeer. So what I am asking is if I should treat this the same way as an understeer problem or if there is something else that needs to be done? Also, please don't criticize me for doing donuts. It is a huge parking lot without any poles or islands, and like I said, it was abandoned. Also, I got my tires rotated after my first attempt yesterday and it did not improve at all.

I've heard of the power steering pump going out under these same conditions. But I don't know exactly if those symptoms you are describing are caused by that pump failure.
Try this thread. Might be of some help.

But I don't know if the problems you are describing are to do with the steering at all, it could be tires being too bald (that surprisingly does cause shake), or maybe check the torque on the wheels (might be loose? Wishful thinking), bent/deformed rims can also cause what you are describing.

I know exactly what you are referring to.
Here's what you need to do:
First you need to begin to do a burnout. As in, get the rear tire(s) spinning before you begin to turn. Assuming you have an auto, hold the brake down a good bit, then give it some gas. Get some wheel spin going, then push the gas to the floor, let off the brake, and turn.

BTW, an 8.8" rear would help you a ton since you would be spinning both wheels.

You DID remember to turn off traction control correct? Or, try making your circle in the opposite direction. With the open diff I would imagine one side might be easier to spin into than the other. I dunno, my sixxer did donuts just fine with the open diff. Hmm..

Sounds to me like more of a problem of not doing the donuts correctly for the car vs mechanical problems. Power braking will do a lot, but be sure to only hold them enough to keep the car from moving forward so it will allow the rear wheels to spin.
