I just purchased an entire Mkv Gti digital airlift kit and have been researching quite a bit about the rubbing issues.
It is a personal nightmare to have a rear bag blow out on me so I want to do the install right the first time and have no worries.
I have been referred to Drew Dorbritz and looked at his D cups, also the performance height brackets from bag riders.
I need your experience and wisdom on the subject of Mkv Gti rear bag set up's and how to PREVENT rubbing.
is this a problem on mk4's?????
FS f1 cups
are they still making these rear bags with plastic caps? quality was most def lacking a year ago, not sure if they addressed this...
the main issue with rubbing comes from the bag sitting in the rear control arm. not saying you can't properly orientate the bag to clear the perimeter of the seat, but it most definetly requires you to jack up and lower the control arm a number of times to find the appropriate position for the top bracket. you'll be drilling and fastening the self-tapping screws a number of times into the body of the car to get it right.
i highly suggest changing over to ss5's or re5's while using a bottom spacer to bring the bag partly out of the seat in the control arm and custom top brackets. for the time and effort it requires you to properly orientate the airlift bags, you could easily make d-cup-esque brackets yourself and use a higher quality bag.
either that or return them for bagyard rear bags and call it a day sans cutting
just a thought before you start cutting your car up to try and make the airlift bags work.
I know that when I had my AirLift rear XL's installed, there was a quite a bit of rubbing on the LCA. The guys at Tomas Sport Tuning had to trim the LCA down to make it fit on top of getting rid of the top nipple.

i have a 2.25" spacer in the lower control arm to get the lift i need from these bags
collapsed height on re5's is 2.9", collapsed height on slam xl rear bags is 5"
this is completely dependent on how you mount these bags
No, it's not a joke, sorry.
After rereading the conversation, we were referring to d-cups + ss/re bags and not a bracket-less setup. Sure, remove the brackets and you will go drastically lower, but that's not what we were talking about.
it honestly kills me that people think d-cups are their only option when choosing a universal bag
no stab at dorbritz or anything, but come on... is everyone that impressed by this design or is it just a mindless solution?
air suspension has become way too "off the shelf" imo, lets see some interesting set-ups with specific design intent
sorry andrew, didn't mean to come off like a jerk
The airlift performance rears are the same bag as is with the Xl's, I think. The difference is the mounting brackets. The performance go a bit higher than the xl's, but low enough for me- I don't want to rest on my exhaust- but they get low enough that my fender liners still hold me up in the rear.

performance rears are a slim bag that doesn't expand as much as XL's
XL's are a tapered sleeve bag, if they're not perfectly centered they will rub on the control arm when you air up and down, if the bracket isn't positioned correctly the bag will rub on the shock bolt and blow
the best way to install airlift rears is using a drive on lift or slip plates from an alignment machine, that way you can see if the bag is touching anything when you air it up and air it out
I prefer air house 2's or SS5's
the D cup positions the bag on top of the control arm rather than an XL bag that sits inside the control arm.
If you're gonna use XL's use the bracket that keeps the nipple, also don't use airlift shocks, you need 80 PSI to get any height out of them.
not sure, my friend johnnyr32 said the most height he ever got was with the airlift bags and bilstein shocks
I just got rid of my airlift rears after running them for 3 years
went to airhouse 2's and bilstien shocks
if you don't want to mod the spring perch, try and get some nutserts from airlift and you can insert them into the nipple then screw the bag to the spring perch
I remember performance rears looking quite different than XLs
