The exact rule says:
The amount of metal in a replacement bushing may not be increased relative to the amount of metal found in a standard bushing for the particular application.
I do not believe that this would preclude the use of any of the RSFB "inserts" but I also believe there is a genuine performance advantage to using a proper one piece bushing rather than the plug-in style bandaid.
Sorry for the slow updates, work has been insane, in fact I have had to drop the car off to a local performance shop to get some work done while I am out of town this week.
But the good news is when I get back to Vancouver next week, we will have a brand new
DiffsOnline LSD, rear Hotchkis swaybar, and M RSFB bushings - should be a great transformation.
The coilovers are here but were damaged in shipping so I am still waiting on UPS for resolution, this process has been dragging on for a month now, extremely frustrating but such is life.
Update when I get back!
