Saab ('92 > 390kKm) did really well on humble steel. Everything from Stuttgart to > Munich at 180km/h to muddy cow paths in Latvia.

But changing the wheel diameter for e.g. low profile might change the gearing and the perceived performance on the speedo. It will of course also improve the handling. Performance drivers usually like a lower gearing. (though I prefer relaxed long gearing) With your fast driving style, you're more likely to hit a stone or a kerb, or even a pothole in the road. That usually puts a big dent in alloy wheels. Steel wheels are much more durable.
