1) I believe the FSAE rear suspension rules are completely open.
2) Wouldn't the solid axle also be cheaper when discussing possible accident damage?
3) Those coming form kart or shifter competition are not going to be bothered by the solid axle.
4) F600 does not have to a perfect design as a transitional car to upper formulas.
We have a shifter we play in. It is going to be hard to keep my kid (driver) in my FV after he sees a F600. Looks like I am going to be learning a new skill set @ the age of 62.
