Wing Style Explanation Requested

[Baptistelake]

Hi everyone, I just purchased a 2004 SV with 16" HPC wheels. The wings on my car extend quite low to the ground (behind the tire). I have seen one other 7 with this style wing but most have shorter wings even with the 15"/16" tires. I have read that there are two sizes of wings 13"/14" and 15"/16" but there has to be a third size with the "longer" wings like mine. Can anyone explain this to me? See two photos - both cars have HPC wheels but they have different wings. The burgundy car is an S3 with a 1.8L K series engine and the red car (mine) is an SV with a 1.8l VVC K series engine. Does the chassis/engine make a difference?

No info on what's proper, but I do know you will have a lot less rocks to shovel out of the seat than the burgundy car....

Yeah, that occurred to me. The lower wings will probably prevent a lot of stones from flying around and a lot of chips. According to Chris Rees (Magnificent Seven), this car was marketed as a road/touring car (which is primarily what I am going to use it for) so maybe that is why Caterham decided to use longer wings. Not sure if it would make any difference aerodynamically being just behind the tire.
