IFS can do that all day long... whats the illusion??? Ive wheeled my toy with ifs for years with a bunch of solid toys and it its by far way weaker and not as fun as the SAS ive done on my 94 toyota youd be left way behind.. But I did have tons of fun with my IFS and impressed lots of people on the trail, who swear by solid axle set ups
What ever makes you 
its all FUN!!!:)
gotta love those yotas!
The "optical illusion" is just a name derived from a picture he posted a while back where it looked like he had a bent shock but it was really straight, hence the name. I don't think RS is trying to prove IFS is better just showing it can keep up with a SA any day.
