See my previous post, the car does not have a wing which gives a bit of a clue as to the nature of marketing such products, neither option makes any performance sense when looked at from the proper perspective.
Sometimes my comments are a bit harsher when read than my intentions when writing them and sometimes I get a bit wound up and spout off a bit more than I probably should. I has something to do with a lifetime of making things actually better, or in some cases attempting to and not turning out quite as expected, first and foremost over style and when a part is obviously made just for style it takes away from performance in most all cases.
Many are new to moding cars and have not yet learned there are companies making products, some with wild claims, some with more modest ones, some with no claims to performance gain but very very few ever admit not actually tested and just making parts to make a buck. I just want to help those not aware to make better choices, those that are more aware or just do not care as long as the car gets looked at more often or looks better just to them. I do not get it but it is not my car so go for it of course unless it is an unsafe mod like severe stance(might trigger a response here but that member does not have severe stance, not even really stance, just a bit overly lowered and maybe a bit of an over stretch on tires but nothing like the cartoon looking cars barely even drivable)
If I had to pick one over the other it would be the 3D and then cover the holes and smooth the airflow to the lip on it so it would do more than just cause turbulence as it does as it built.
If somebody offered to pay me to run the "spoiler risers" I would not accept it, just to far from my performance perspective mind to do so.
--------
All that yammering aside, if somebody took the time to do real validated testing and showed a performance gain and no negatives from either mod I would be more than happy to admit I was wrong and the support the products and even consider using one or the other but that is highly likely to never happen and highly likely not possible with them.
I am putting a real wing on my my car when I get the time to design the mounts but I plan to only run it on track.
