well young man get out your tape measure!! measure between the sides of your tunnel first. 1/2 inch extra clearance i think. Now look at your track drivers and measure between the drive lugs, now look up track drive pitch. Now oyu know the rest of the story!!
Yes it will fit you might have to grind down some rivets. Lots of guys put 16" wide on there ZX's and its a great upgrade i wish i would have done it to mine.
I have a 151x16 wide in my 03. Just put 2 washers on both sides too spread the tunnel for alittle more clearence grind down some rivets and maybe bolt heads in the front. I got mine machined down to half the thickness.:d
