Because race car lol
Forgot the average age on the forum was 67!!! Lmao
Ideally the closer to the front is better but not possible due to the internal webbing, high pressure at rear and low near the front due to the air coming off the front of the car. Again the fiesta vents where chosen with shape in mind and trying to match with the curves of the car. Gurney flaps would help no end but it ain't a race car so not bothering. Heat does rise out if there a lot and at low speed should work perfectly high speeds another story, anyway my car do what I like.
Just off up tesco to cruz init!!!?!
