Adding coil spacers

Alright so I'm a somewhat a newb when it comes to technical things on my jeep (08 2door jk 6spd), but I have 3.5" Rough Country Series II lift which came with shocks springs and front control arms also DPA and rear sway bars and extended bump stops etc. So I have a few questions:

1: can I add 2.5" coil spacers with shock extenders to this lift? And what will be the consequences/issues/extras needed etc.

2: my lift came with the front control arms but I have a set that are adj, so I can put those on, would it be necessary/better?

3: opinions on shock extenders/coil spacers?

(This jeep is a pavement princess for the most part btw, has been in some mud occassionly but nothing big.

1: can I add 2.5" coil spacers with shock extenders to this lift? YESAnd what will be the consequences/issues/extras needed etc. Severely decreased ride quality, drive shaft wear

2: my lift came with the front control arms but I have a set that are adj, so I can put those on, would it be necessary/better? Upper control arms will allow you to dial in more caster, but at 6" of lift you won't be able to dial in enough

Answers above in RED but I gotta tell you, I think it's a it's a really, really, really BAD idea.
Your 3.5" lift is plenty to run 37s.

Also here's a thought; RC springs are known to sag, maybe all you need are some better springs. @SoDakSooner has the RC 3.5" lift, we swapped out his coils with 3.5" RK coils a couple of weeks ago. Hopefully he'll chime in but I think he got over an inch more lift out of the RK coils.

His ride is on the left with 35s, mine on the right with 3" lift + 1.25" BL on 37s. He sits a little taller than me.

I gained 2" in the back and and an inch in the front with the RK springs, and I have a bunch of stuff hanging off the back. My rough country springs made it closer to a 1.5 to 2" lift. They sagged badly, but what do you expect for a $500 kit that includes shocks(it was on the jeep when I bought it). I definitely had the lowrider reverse rake going on.

We kind of had to chuckle that I was taller than @Bluebabysound during our last outing.

FYI...with the additional inch or two on mine I am already seeing more issues with the driveshafts. Need to add exhaust spacers now, and new driveshafts are creeping up on the mod list.

BTW, with that kit, replace the shocks too. I had one blown one. Now running Bilstien 5100's. I am slowly getting rid of the rough country parts. All I have left is the rear track bar bracket, dropped Pittman arm(probably do a high steer setup), the front control arms(which actually are pretty beefy) and the bump stops, which will most likely stay. They are just bump stops. All the front axle RC stuff is now ARTEC, and welded on.

BTW....If you wait for sales, you can get great deals. I got all 4 springs for less than $270 with free shipping.

As far as lifts that tall(6") your at a minimum, no matter what you do, steering geometry will go to sh#t.
