I'm a bit puzzled by how they determine the amount for the extra mods.
For example: I rang up to insure a fmic and pod which costed around $50 extra, I called up not long ago and added window tint, exhaust, side skirts, turbo timer, fuel pump and it only costed $33, I mean wtf surely those mods are worth more than the other two? I would think that the extra you have to pay might have something to do with the admin costs, but surely it shouldn't vary.
I'm going to query it when I call up next for when I add my suspension setup to my policy. I'm also going to consider switching to third party for my renewal, comprehensive price is just bs.
