           Analogous observations to China and Malaysia are noticed in Turkey like the greater 2011 top speed at long straights due to KERS and DRS and lower speed in slow corners because of lower grip provided by Pirelli tyres compared to Bridgestone used last season . Pirelli tyres lower grip is supported also on other strong facts seen on regular base, like the greater stopping distance, the increase in braking time with a significant decrease in maximum deceleration .
