Anyone done it on here? Tempted to lineup a rear subframe and get it powder coated and it seems sensible to take the opportunity to upgrade to a FL rear subframe in my 2003 PFL.

Got a couple of questions;
Are the changes worth it?
Do I literally need just the rear subframe and top arms, and everything else front and rear stayed the same? Is there anything else I need front or rear to get the setup right?
Did honda change anything at the front at the same time as the revisions to the rear?
Are there literally only two versions of the subframe? Or do I need to watch out for what I buy.
Does it bolt directly to the PFL monocoque?

Thanks in advance!
