60 vs 55 spring perches

[jm599]

I'm putting 60 axles under a 55 project. Alcans for a 55 on the way.
on the rear having to move the axle perches in 3 inches.

I have noticed a difference in the perches.

55 fairly plain, 60 has rubber pad insulator with large retainer, requiring large hole in perch.

Question: is there any major advantage of either way?

Better ride or no big deal?
Thanks for any help.

all the rubber pad does is isolate noise for a quiter ride, doesnt do anything to improve the ride. you dont need it unless you want it.
