2 of the guys who pit inder my awning ran them the past 2 years & yeah they are pretty tough but they seem to wear out quick [:'(]
i also know a couple of other guys who bought them because of price & then bought other cars as they thought they were slow!
these were guys running them in A & B finals at National level who needed the few tenths a lap they were losing to other cars!
in fact only 1 guy in our crowd still has one & he's been spanking his monkey over the pics of the 808 so go figure [:-]

but yeah they are pretty durable at their price
