You know what gets me, I've got "Minerva's F105's" on my RX8, for road use, perfectly acceptable and I couldn't give a monkey's toss what others think... when I replace them, then I'll be getting better tyres because the wet performance isn't what I want in a RWD car, however, for now and in the dry, they grip perfectly fine and I'll just use them for track when I upgrade to Goodyears. When it rains, I just don't boot it, but that's what I'd still do with top tyres on.
Try them, see what you think and if they work **** everyone else mate, what does it matter as long as you're happy with them. Just be wary that in the wet this is when cheap tyres lose there browny points, but I'll tell ya what, in the dry in normal conditions, I'd love to see the "track" experts on motors do a pepsi challenge on them rofl.
EDIT: Just make sure that if buying you shop around as you can get some deals on top makes now i.e. 205/40/18 Good Year Asymmetric 2 £102 inc VAT... now that's a steal.
