Best way if you haven't installed them yet is to pop out the pistons with an air compressor and lather the grease on the sides.

Is it feasible with replace the dust seals without removing the caliper? My thought is remove pads, remove caliper from knuckle, then gently use pry tool/pliers to remove dust seals and insert new ones. Doable? Worries about getting the new dust seals in the correct position (so that it seals properly)

Absolutely, but I was an early installer and we hadn't tried RRG at that time. I had to improvise.
I think it's doable.

So I don't drive my car hard. I don't track it
I don't do autocross. Hell, aside from on ramps with no traffic around, I hardly ever even hit peak boost. Because of that, I don't slam my brakes or press the brake pedal as hard as possible.
Well, today I did, and could feel my pedal very slowly sinking. Which isn't good.
Get home, and can see it immediately. Brake fluid all around my wheel and wheel well. Which means a piston is leaking.
Yup.
Take it apart, which I'm getting very good at by this point, and sure enough the inner seal is knicked. Luckily, still have plenty of extras. Put it all back together, bleed them, and they feel good so far. But it was raining, and really didn't have a chance to press them too hard.

You have terrible luck with seals.

Either that, or it's something I'm doing wrong. But there isn't much room to mess anything up ¯\_(ツ)_/¯
I don't get it. I've had these on for two months now, and probably a couple thousand miles. Don't know if something changed, or I never applied enough pressure to the pedal to push out fluid. Because I've definitely never had any leaking fluid the last two months.
Have the car sitting like this in the garage right now. After getting everything together, took it for a drive and it felt fine. Was raining, so couldn't really tell if it was water or fluid on the wheels. But with them off in the garage, I turned on the car and pressed as hard as I could on the pedal. Harder than I would ever need to while driving. To the point where "How much pressure can the MC take before it blows?" popped into my head. Didn't notice any fluid leaking out of either side, so hopefully fine now.

What brake fluid are you using? Didn’t someone running Castrol SRF have an issue with fluid seeping?

Using Pentosin Super Dot4. Since I don't track my car, I didn't use performance oriented fluid.

What rotors are those? They look great.

Stoptech Drilled & Slotted 127.33112. Them looking great is the only reason I spent $320 on rotors lol.
I have the same, and in hindsight I should have just sprung for 2-piece guys to save weight too. They do look great though!

I'm in it for aesthetics only, went with R1 concepts Geomet rotors, Mk6 R... they were $190 for the pair. Regular price $270 but R1 has somewhat regular 30% off sales.

My last set (on the stock brakes) was R1, but just the e-Line drilled & slotted. No issues with the braking performance, but wasn't happy with the way they were aging. After a year, even the 'coated' sections were starting to show some rust.

I wouldn't be happy with that either, hopefully mine hold up over time. I've had these on for 6, maybe 7 months and they still look new. Car has seen rain at most 5 times, until the last couple months it was rarely driven and it barely rains here. I do go through the car wash once a week though and that hasn't been an issue thus far. Hope it stays that way.
