corners? the stiff sidewall MIGHT hamper your straight line on the v700's, but you will get a little better cornering out of the rear of the car. now if you go all the way around with the v700's then you will be sweet on corners.
however
if you want some better straight line the 555r's would be better. if you do not go all the way around with the v700's...i would say 555r's would be better. i would lean to the 555r's anywise. they get kinda slick after a while though. kinda hard also. get them warm and they are good.
