Well I've done 4 track days and roughly 1000-1500 road miles on my current set that still have roughly 4-5mm left (they come with 8 ).
1 of those days was fairly steady but the other 3 I went through about 1 3/4 tanks of fuel so were fairly heavy on the tyres, also finished off a set of brake pads.
They are crap cold, crap crap crap crap. They aren't dangerous but you just need to be aware that they take a few miles of road driving or a couple of steady laps to warm up otherwise the back end as twitchy as it is will potentially step out
.
They seem to react well to a bit of heat but drop off quite a lot if you overheat them, smooth driving however and they seem to keep going forever. I got tired before they did on my most recent track outing
In terms of their performance, I wouldn't recommend them for drag racing I just don't think the tread pattern is right for that :s.
On a track though actual out and out grip is pretty amazing once warm, I've followed/passed and maintained distance with plenty of cars with much more expensive rubber (and even more power). They give you a lot of confidence as they tend not to let go suddenly, a bit more progressive.
In terms of using them on the road I used them back in the beginning of the year, you know..... when we had the crazy snow storms and really crappy weather. They worked fine, I really couldn't tell any different to the contis.
We've had a lot of wet weather recently and again they work just as well in the wet as any other tyre.
It goes without saying don't plough into standing water but who does that anyway?! (ok maybe once
)
Would I go with them again?
Possibly not, they are more expensive now than they were, I bought them at £105 a corner.
I'd like to try something a bit more focussed, there a few tyres from the likes of Silverstone/Federal etc. that look quite tasty but obviously will cost more!
BUT for a tyre that lasts so long yet still performs so well they're an out and out bargain.
