You will only have to use the steering sub trim to finish the alinement .
Try this , car will track like a arrow when done.
Both sides of the Ti rods will be equal & even .....

As I said, the RPM cups have shorter shafts than the stock AE cups, the manual gives measurements based on how far apart the cups are apart, not the total length of the arm, and even then the RPM's are thicker which is what makes them hold on tighter during hard landings and hitting pipes.
I'm not sure, but the "long shank" RPM cups may be the same size, but I haven't compared those.
