Few weeks ago I had the opportunity to drive at Vallelunga (Rome) in between the races of 360 Challange and NGT. The last used slicks unfortunately!!!

After few laps, as my tyres became hot, they absorbed a huge quantity of rubber pieces, with really unpleasent consequences:

- the vibrations increased and I didn't feel safe in the fast corners :evil:
- the sudden release of a big rubber pieces destroyed the carter just in front of the wheel (posterior left). 500 $
- today, after more than 600 km, the tyres are still completely coated of slicks, quite impossible to clean with normal devices (I believe that the only possibility is to warm the tyres with steam and remove the rubber with a lot of patience) :evil: :evil:

Anyway, I had already taken the decision to install new tyres, so I will not try myself in that job. But ... lesson learned :roll: :roll:

well, try and find a brihgt side
those first few laps, did you have fun?

Yes, it's always exciting for me to have the possibility to drive on a circuit, but there are better opportunities.

I believe that an hairdryer is a good solution as well, but cleaning a slick is eased by the smooth surface and by the opportunity to use mechanical devices. On road tyres you have to clean the interstices one by one :x
But other consequences are even worse: the case that was broken by a rubber debris protects the water cooler. I don't want to imagine what can happen if a rubber debris enter the cooling system at that speed and temperature!

The events were part of some National Championships: Ferrari Challenge Pirelli (360 Challenge); GT (360, Maserati, 550, Porsche and Viper) and N-GT (360 GTC). Free laps for private Ferrari in between the races.

There was also (in exibition) the new Saleen S7 both in the road model (575 bhp) and in the sport one (740 bhp) that will substitute some Vipers in the GT competitions next year. It's really impressive.

.

but about the tyres, where these already older and in need of replacement or still pretty new?
if still new enough, then you could try cleaning them, winter is coming up anyway, so drivingtime will be limited anyhow.

No, they aren't new: I had already decided to change them after Vallelunga.

and well, those burnouts might be difficult when you try to place the reartyres up front :wink:

Right: anyway, after a burnout I found less rubber on the external surface, but more into the channels, where it's more difficult to remove. :x
