VTEC Suspension

I am looking to upgrade my struts and springs on my 1994 EX sedan.  When I look up suspension kits from the various manufacturers, the vast majority exclude VTEC.
 
Does anyone know what the difference is between the VTEC and the non VTEC applications?
 
Thanks,
Fred H

Probably the spring rate??
