There's a simple method, Christrong, you can try that a Porsche specialist I know uses as part of the way to gauge the efficiency of a car's suspension before he works on it.
First, you need an empty roundabout. Not too big, not too small - you'll find the right size when you try this. Then, you need a friend to read the speedometer, so you can focus on the job. Having his/her weight over the front end helps, too.
The idea is not to tear-arse onto the roundabout, all wheels screaming, but to drive whole circuits (of as near the same diameter as you can manage) at a fixed speed, increasing by 1mph (or as near as you can manage) per circuit until you begin to lose adhesion.
Try it. You may be surprised at the outcomes.
