anybody using Ground Control Articulating height adjuster?

I purchased the GC articulating perch as it came highly recommend by Bimmerworld. my installer tried putting them on with a 9" swift spring in the rear and it seems there isn't enough adjustment for such a long spring. for those of you that have this perch, what size spring are you running?

I don't think it matters but the dampers are 1WNR MCS.

I have the Rogue version on my E36. Screwed all the way down like a normal spring perch they obviously have no room to articulate. You probably need 1 inch shorter springs than you would use with normal perches.

are there issues with running a different brand spring in the rear but with the right spring rates? I'm able to source eibach rear springs locally in 7 or 8 inches but my fronts are swift springs

I am not a spring expert but as long as they are the same diameter and rated at the weight per inch you want they should work (Swift may rate in metric but you can do the math to find the closest in a lbs/inch rated brand. The experts debate weight and wire type and thickness and coil bind and each thinks one brand has advantages over another. Eibach is good, Swift is good. You can order Swift online and get them in a few days if in stock.

Updating this thread in case people search for this same exact issue in the future.

Turns out that the GC articulating rear height adjusters can be cut (they were designed that way) for cars that need to go lower. I spoke to Trevor @ Ground Control to verify this. Even though 8" rear springs are the preferred size, 9" will fit if you cut the rod. The only reason why I went with 9" springs was because it was recommended by Bimmerworld. I got in touch with my sales guy today and he acknowledged that I should have got 8" and the initial recommendation was a mistake. Not really making an effort to make it right. Instead, he countered with selling me a brand new set of springs which isn't really making it right. A bit disappointing given their reputation but it is what it is.

My installer will be cutting the height adjusters today and hopefully all is solved.

Moral of the story:

If you get the GC Articulating Rear Height Adjuster - get a 8" spring
If you get an older-style height adjuster, a 9" spring is fine.

Wow. I had an amazing experience with BW and yeah I think most people would've told you right off the bat 8in rear spring.

Even though I had a great experience with BW and will be purchasing and consulting with them again in the future; I personally wouldn't let it go. Can't shrug it off and say my bad sold you a WHOLE 1 inch longer spring and not fix the issue as a company. Speak to a manager or someone else I'm sure BW wouldn't want this to be representative of how they deal with errors.

Yeah - the experience was great until something went wrong, which in this case, was on them. The guy I was dealing with was super attentive until I discovered the issue. Then he just stopped responding to my email. I had to call to get it confirmation that their original estimate did in fact contain a mistake. I was going to order Rod Bearings from them and a few other items but I'll just take my business elsewhere.

The salesman did not really understand how what he was selling works. That is unfortunate. Sometimes when I deal with Bavauto, the salesman will read from a comments section presumably made up of comments learned from customers, users, etc. I have added to those comments before when I returned products that dud not work or had issues. Hopefully Bimmerworld has something similar so it can better serve the next guy and not lose customers. A salesman canít know how all products work on all cars.

Please keep in mind the GC articulating perch is for a "race" application. You may need to do maintenance on the ball bearing inside every now and then so they function correctly.
