Interesting, if the rear end links really are wider. With the Exotek car having very wide links and the V2 being narrower link to accommodate the body there may be some differences there. A friend and I were talking at the last race we attended that maybe with the rubber tires there was an advantage to having a wider link setup. The advantage is not so great over the side spring, so you can get away with a little softer spring, especially on high traction. The original V2 was shown with foams so maybe this is a response to rubber tire racing. I know on my TOP car, which has even narrower links than the V2, I have run some of the hardest side springs available.
Not sure though, the pictures are small
EDIT: IS that a fixed upper arm? Could it be they are going to a setup like the F103 front end???
