For the third time this season, the Teams' Championship sponsors parked up their eye-catching pink stand on the outfield and watched as the crowds flocked to pick up HiQ hats, large foam spanners and all number of T-shirts and goody bags.
The HiQ team, together with the pink ladies and special guest Beverley Edwards - who won HiQ's national grid girl competition - managed to boost the championship total to more than £15,000 for the season.
In the process, HiQ smashed the £80,000 mark for Breast Cancer Care since partnering with the charity in 2009.
HiQ retail marketing manager Geraldine McGovern, said: "We have enjoyed a fantastic season of fundraising and it is with thanks to everyone involved that we have raised so much.
"There was a great atmosphere at Silverstone with fans going above and beyond to donate to Breast Cancer Care, a charity very close to everyone's hearts.
"Fifteen thousand pounds is an incredible amount to raise over the season and we are proud to have totalled over £80,000 through various fundraising initiatives applied through our project pink programme.
"We are continuing with our sponsorship and charity partnership in 2012 so we look forward to continuing in our fundraising and turning the grids pink once again."
