The aluminum car is probably a Kirkham or CSX.

As for the handling, it can be understeer, but generally we're talking oversteer. "Snap" oversteer. If you plow into a corner too hard, the car will understeer, and if you have sticky tires and power out too hard, it can also understeer. But when the rear decides to break loose, you generally don't get much warning or much chance to catch it. It'll swap ends in a hurry. I've done it in autox before, never on the open track. I think it's pretty common to any short wheelbase car with a 50/50 weight balance. My MR2 is notorious for this. But when you add high horsepower, it can make for a wild ride. If you drive smart...don't brake mid-corner, don't lift mid-corner, you should be OK.
