On a Z v.2 you need it as a spacer to add a triple joint ring if the application calls for it -- on the NS v.2 the ring can fit down in the gap on rearward stroke. Typically Z v.2 don't need the triple joint rings -- but if someone needs one for their application we can space the basket up with other methods.We found that it could actually make inductance too low for some applications (higher powered daily mostly) so ended up removing it on both the Z v.2 and NS v.2 -- both drivers still feature large internal shorting rings, which are more critical on over-hung anyway.</blockquote>
