Hmm... I thought it was pretty ok. The GT3 I sort of bought was far harsher, a real brain-shaker and it would have been nasty on a run or anywhere I didn't want to pretend I had any talent. I do need to get out and take a Vantage for a longer drive in case it turns out they're are actually pretty nasty on a long, steady run, such as with Mrs Crud.
As for switching the dampers, the difference between standard and track was night and day. A magnititude more of a difference compared to the GTS in normal and sport, and the handling in track was tremendous. Immediate responsiveness from the wheel and properly planted (with just enough wriggle thrown in to keep you on your toes). Wouldn't be a lot of fun on a crappy road, though.
