There are two types of Bumpers being fitted to Bentley cars - Ridlington's and Wilmot's. The weights are approximately the same both weighing 56 lbs. per set "front and rear". Approximately 50% of the cars are being fitted with bumpers, but in some cases they are only fitted to the rear, in which case 28 lbs. is added to the weight of the car. LA.{L. A. Archer} | ||
