DRC suspension upgrade for 2020

[DKP]

Yes that was just shocks. And now you have me thinking about the other bits and pieces. I was working on the assumption that the rest is still sound. Car has resided in Colorado and Florida. Always garage kept. Zero corrosion, no winters etc. 80k on the clock. Garage queen for the most part. But I may start shopping around for those items. Just on the basic principles of hoarding for the future. Anyone have those part numbers written down anywhere?

According to Jim Ellis parts it’s 4B3616807A and 4B3616808A, each is called “Cental valve with lines.” My car was an Illinois/Ohio resident, and this I cannot say the same for corrosion/winters. Shop says the reservoirs are so rusted they’re not sure they can simply un-bolt DRC components to uninstall them.

Thanks for the numbers. Yikes that doesn’t sound good on the corrosion front. Damn mag chloride. Hate that crap. Do you know Does lines mean the ones at each corner or lines to each corner?

I do not, sorry. I’d need someone with more parts savvy to assess what’s needed to actually replace an entire system.

[DKP]

Yea I maybe should have thought through all the possible failure points before I bought all 4 shocks. Could turn into way more work and money then I had in my head. Especially since I’ve looked at the new A6 Allroad. Me like. Then you do that mental money tally in your head and think with what I’ve spent on my RS I could have almost bought the new Allroad. Silly humans.

Have you ever thought about getting billsteins?

As a matter of fact, that's where I've decided to go... with the B6 Performance!

Good chance to compare the V3s with Bilstein

[AudiPilot]

It was indeed a good chance to do that... also the 10SEC tune vs. my EPL... let’s just say I’m jealous of that tune now, and need to get a TCU tune (maybe different ECU as well), because the 10SEC/GIAC combo is pretty impressive. Then again, there’s probably some “enabling” there having Apikol intakes and much more air intake than I do.

I’m sure @kevcp will add a bunch, but he put me through the paces with a full swap out (plus rear Hotchkis — indy shop replaced the front OE posts with bolts that were impossible to access, so only did the rear) in about 10 hours of work in a single day. Was not without excitement, with a very strange strut mount that came out of the right rear... zoom in on that and check out how the strut end nut wore into the top mount. So that’ll need to come back off (using my new skills) at a future date with the proper part.

All in all, extremely grateful for the expertise generously shared today! Makes owning the car more fun and more rewarding. Oh and it turns out that only one side of my DRC had any pressure... who knew!?

[DKP]

Hey Audi Pilot. Are you back on the road. Also I had another question. Since you only had pressure on one side when you got to work I was wondering what the handling characteristics were. Was the car just floating along like some 60,s barge.

[AudiPilot]

Thanks for asking! Not back on the road yet... car is at New German Performance outside DC... since we didn’t have the mounts ready to go when the struts were off (no idea they’d be bad, and I’m out of time, moving to CA on Saturday), I’m having the shop do it before it gets shipped next week. Fingers crossed it’ll be ready to drive upon arrival.

Having never driven any other RS6 (and without enough general experience to know what’s “off”), I honestly didn’t have anything to compare it to. @kevcp noted it was quite floaty, especially compared to his on V3s!

Wish I could have chimed in sooner on this....I changed my email and got locked out of posting permission for a while....I did the Bilsteins on mine since my DRC was blown when I bought it (knew this already) and the car came with a boxed set of H&R sport springs in the trunk, ready to install. Overall, I'm happy, especially since I picked up a brand new set of shocks and all mounting hardware, rubber bits, bolts, etc. for about $800.00 all in (since I had springs) from an Audizine member. The car rides well on the road, not too harsh, but it could use a little firmer hold on the curves...still a little boat like on long sweeping curves. I was way outgunned by a new Golf R, not for lack of power, but for me not wanting to plow off of the road on 100 mph curves. I do have upgraded H-Sport sways front and rear as well. As I mentioned, for the price, definitely great (and a nice drop too), but if I had to do again, I'd go V3's or 2Bennets...

Good call on that choice against the Golf... Even a quick drive on the V3’s was enough to know they’re the real deal, the price was just to steep for me at this moment in time. And you definitely beat me on your “all in” price for the B6s... But I’ll enjoy them when I have the car back, and sometime down the road when there’s some surplus maybe I’ll pop for the V3s! Your car looks great!

increase damping if you’re able to adjust the struts

RS6 needs more damping on the front from stock setup. Even the V3s need 2-3 clicks more damping

I appreciate that input. Unless I’m mistaken, the Bilstein B6 doesn’t have any damping adjustment.

Thanks!...I love the car and it is certainly not a disappointment, but I know it could handle better. At the time, $$$ was a factor, so it was 100% the right choice at that point to get the car back on the road...it was blowing fluid all over the front rotor from the soft line and making a mess of the brakes and wheel, so not really drivable at all at that point.

Good call on NGP...I love the guys up at Aberdeen and I'm sure they are just as good at the Lorton shop...just had them align mine finally after a year and a mega-failed alignment at the local stealership! They'd be a first call for any paid work, but I try to do as much as I can myself, including an engine pull in the next week or two...

Late to this thread. Obviously per the other post I made today I went with 2Bennett’s package. Only back 4 days so no real “testing” until new brakes properly bedded. But so far I am super pleased. Good solid control maybe a bit stiffer than what I vaguely remember working DRC to be. Happy with my pick.

The Koni Yellow struts work amazingly well with the stock springs, decent ride height also. If I do go coilovers it will be the Billstein PSS9 as they are reviewed for great comfort/performance for those wanting a sporty ride that isn't too harsh.
