HiQ's team of pink girls were on hand to give away caps and replica cars in return for donations to the cause.
And Team WSR's contribution - both on and off the track - were praised by everyone at HiQ.
The outgoing champions and eBay Motors supported WSR team agreed for drivers Rob Collard and Andy Neate to boast the HiQ and Breast Cancer Care pink logos on the rear quarter panel of their cars.
HiQ's marketing manager Geraldine McGovern said: "Dick Bennetts and his team were brilliant in supporting us, and we want to thank them.
"To see the pink logos on the grid was great exposure and tied in nicely with the amount of pink on show in the grandstands.
"It was nice to see the lads get in touch with their feminine suides as well. The colour pink matched their complexions!"
