V's are what are fitted to the Trophy as standard, which are fine, W's dont have the stiffer wall so you will find a little more roll when in corners, but the ride will be slighty smoother and less harsh.
TBH I have always stuck with what was on the car from standard, if the Renault engineers have spent the time testing different options the ones which they choose are bound to be fine for everyday normal driving. Its only once you start tracking the car you need to look at other options, such as road legal track day tyres such as the Toyo or Yokohama's.
With regards to the Tracking, if you havent done it recently i would suggest spending that little bit more and get them laser aligned. i had mine done when i first got it as i felt the car was pulling to the right a bit, got it done and all 4 of the wheels were out by around 1%. Since having it set up the car feels totally different.
