Yes, but should not be enough to cause coil bind- just remember that's 
the enemy.  The manufacturers design the system so there should never be 
coil bind through the normal suspension travel, so there is room, but 
not to any extreme.  That's the trouble with all spacers that just take 
up room- you have to keep the coil bind in perspective. Raising the 
spring perch or using a spacer just increases the amount of compression 
on the spring and gets all the coils closer together.  Taking a piece of 
the spring out of the action by using a spring rubber actually raises 
the effective rate of the spring, actually making it less likely to go 
into coil bind.

They are selling stuff to racers, and expect $$ for a gold plated piece 
of rubber.  The cheap ones work just as well in this application as the 
expensive ones.  Plain rubber ones should be available for under 20 
bucks, just remember to zip tie them in so they don't leave. Jack up the 
side you're working on first to open up the coils (and use jack supports).
