With all the talk about aftermarket shocks I'm surprised no one has mentioned these other skid modifications. The Adjustable Remote Coupling (ARC) is basically technology borrowed from the mountain biking industry and uses a rear mounted skid shock with a handle bar mounted switch (think dropper post on a bike)that controls the amount of lock out of the rear shock. You can adjust the degree of coupling on the fly.
Picture dropping steep tree lines laying deep downhill carves and then needing to lift the skis and wheelie over a creek at the bottom =>lowest setting of coupling (stock)
Then on the other side of the creek immediately needing to navigate into a technical sidehill through some tight trees where more control is required => flip switch to setting 2 for more coupling.
Then getting cliff'd/tree'd out and needing to make an emergency **** hook and pin it up some steep exposed long climb to safety => flip switch to #3 pin it and pull the hill with (near) full coupled skid and controlled ski lift.
Rinse and Repeat all day with out getting off the sled to adjust coupling blocks.
I love this concept. The price seems very inflated for what you get however, and at the end of the day you still have stock shocks in the stock skid (no proper reinforcements is also a concern).

Now picture a full K-mod skid. Here is the turn key Ski-Doo skid for the T3 but there is a G4 one in the works.

The K-Mod has Raptor 20 position compression clicker shocks and billet adjustable coupling blocks. While the coupling blocks are easy enough to stop and adjust, I've got handle bar controlled coupling stuck on the brain. So what I'm saying is picture the K-Mod turn key skid with the handle bar operated adjustable coupling. Would this not be the shizznitt!!??
Anyone else catchin what I'm laying down here? IMO improvements to the rear skid like this are the single biggest gain to be had on the G4 for those of us that want to keep our warranty intact and are only interested in non-aesthetic functional mods.
Cans, wraps, turbo's blah blah blah
