Saturday 31 May at 10:18 : The Montreal circuit's famous kerbs have been changed ahead of the Canadian grand prix there next weekend.

Previously, it emerged that organisers of the Circuit Gilles Villeneuve event would modify the wall adjacent to the left-hand kink prior to the hairpin, in response to Robert Kubica's huge crash in 2007.

The changes are among $4.5million in improvements at Montreal this year, including better paddock facilities and several resurfaced corners.

It has now also emerged that several of Montreal's famous corner kerbs - including the one preceding the so-nicknamed 'Champions Wall' at the last corner - have been made significantly less harsh for the 2008 running.

The high kerbs at the Montreal layout, located on the man made Notre Dame island within sight of the city, were previously famous for their difficult characteristics.
