Smicky, If you opt for a cheaper tyre you are most likely going to lose performance. Like most things you get what you pay for. I've had the S03's on previous cars and they are one of the best gripping tyres around but they wont last long at all. I could only manage 20k out of a set. If you do pay a bit more for a tyre, say the Michellin PS2 then they will last longer and still give excellent performance. That's why they cost more. You might be able to try these new Marangoni Mythos that a few people are running here. Not sure on price but they are grippy from what's been said. Benny
