Everywhere I go I'm looking for 'test tracks' - I'll have to check the legality too..if it is not a public road and instead is private property like a car park, who says I can drive around in circles madly?

I was thinking a lot about this testing last night, figure 8's, slaloms etc...but I think the steady state circle is the best approach.

Most circuit corners, particularly high speed ones are fairly steady state or constantly turning.

I also think you have to test the car turning left and turning right - as in some cars this is different. This should also show up any alignment/ loose bearing problems too.

If we come up with a standard too the result will be reasonably comparitive, so everyone can have a go. Surfaces, tire pressures, "track" temps, tire sizes etc...will vary as long as it is done in similar types of conditions the info should be comparable.

Glad to have some reassurance, as I can't think of a better way to test cornering that is repeatable and does not rely (much) on driver skill.

Oh - I have the XR6 (which will be replaced with an XR6T very soon) to benchmark against. I know a Falcon aint much of a benchmark....maybe I can get a Skyline or even an early series RX7 to have a crack.
