As I said in an earlier post - there's actually a hell of a lot more grip to play with than is immediately apparent. There's plenty of warning that you're approaching the limit, and if you do push too hard, bottle it and lift off, the tail breaks nice and progressively - particularly if you add a couple of psi to the "book" rear tyre pressures. No spacers on mine as I quite like the slightly lively rear end. I'm running Koni dampers with Vogtland springs, and also a set of Cupra 20vT wheels with 195/45R16 Yokohama A539's.
With a bit of familiarity and a bit of commitment it's a car that can really be hussled along at far greater pace on the twisties than the numbers on the spec sheet might suggest - and I find you can return pretty respectable economy even whilst "making good progress" on a B road blast - mid to high 30's sort of respectable. Great fun, and I still get a lot of enjoyment from mine, which i've owned from new - shame i'm overseas at the moment and missing out on the road rally season.
As for performance at 90+, yep, that's true enough but how often is it really a concern (officer)?
