my advice would be to get on ebay and look for a cheap set of tracking guages, we picked up a set of techlamit (sp?) optical guages for £50, worth double that for the results they give and the ease of setting IMHO.
On the 205 (completely different car admittedly, the ride height is slightly higher than standard (gravel spec) and we run 1 degree toe out. played with it at oulton a few weeks back as we do the odd tarmac event and we found that parallel gave bucket fulls of understeer, 2 degrees toe out made the backend want to overtake the front, but 1degree out brought it nice and balanced.
