in the imca mod class what roof size would be best for both motor options?
sorry if I worded it weird. so if I go with the open motor is it better to have a longer roof since I don't have a spoiler or is a smaller roof better?
not sure honestly ha ha I'm clearly not a genius on this aero stuff that's y I was asking.
i just put the max width/length roof on mine. sure looks big
Mount the roof taller in front slopped to the spoiler that would be sure to push air to the spoiler! Sorry I had to! In all there isn't any roof that will direct air to the spoiler unless the spoiler is fairly good sized. Also the roof being flat and sloped forward is going to apply down force over the center/rear of the car son all in all a bigger roof would provide more down force then a smaller one. But is the down force where you want it applied is what you need to think about. The spoiler applies it at the rear of the car. Also the smaller roof will provide less wind resistance and in turn less down force over the center to rear of the car.
