Diffuser question
While researching different options both on this site and elsewhere I didnt find an answer to this question:
Does a diffuser need to cover the whole of the underside of the car from the rear axle back to be effective? Or to reverse the question: Does a diffuser that is only about 1.5 foot wide do anything because the air can still get up into the underside of the car?
