It's an opinion but difficult to get the power down and stay down with the rear pogo stick. You can play around with oil/ air gap at the front to fine tune a reasonable fork but the rear?? Soooo bad.I disagree,I think the front end is more important at the track then the rear
they are both important but If i could only do one I would do the forks
actually I did this in the early 2000's when I was racing a GSXR750. I sent the forks off to traxxion dynamics and was on a stock rear shock for a full season. I was racing in the expert class in CCS Florida.
