I am looking at replacing the Kumho tyres on our mapped GTi and want some that will get grip on the front a little better, obvs I know its hard all the power through the front wheels but I am sure we can gain some more grip though better tyres, I know most people love the Michelin PS4 but they are just too expensive in 19", so its come down between Pirelli P-Zero's or Goodyear Eagle F1's Asymmetric 5's, does anyone have experience of these on a mapped GTi please?
