Dunlop Formula Rs or Pirelli P Zero Corsas ?

[55jnj]

Has anyone any experience of using BOTH these tyres & if so, what was your experience of each ? (Handling differences, life expectancy ?) - Track days only, no racing. Use P Zero Cs on my Chim (track days only but very pleased with their performance - get approx 5 track days per set) & have just invested (£800 ish) in a set of Corsas for the Tuscan as intermediates, but would welcome views on comparisons of the latter with the Dunlops.
