Throughout 1988, Senna had copied Prost's car settings feeling that the Frenchman had a better handle on setting up the McLaren (after driving Prost's spare car in Brazil he found that his team mates settings actually suited his own driving style, plus they were easier on the car). At Spa Prost decided at the last minute to alter the settings on his car by taking off some wing for more straight line speed in a bid to gain an advantage. Unfortunately for the Frenchman this had a detrimental result and he was unhappy with the balance and handling of his car in the race, compared to Senna with Prost's original settings who reported no such problems. At the start, pole sitter Senna had too much wheelspin and Prost was able to take the lead. However, the first time through Eau Rouge, Senna, with better downforce and grip, was clearly quicker and easily retook the lead after he slipstreamed Prost on the Kemmel Straight and out braked him at Les Combes. Senna powered off into the distance while Prost, struggling with a car that was no longer handling to his liking, settled for second place.
