Actually I have not installed them yet I have everything ready

Powder coated
New ball joints pressed in
New bushings for the djm kit
New sleeves fit the djm kit

But I’m waiting for the sway bars to get here to do everything one time. But if there not here soon I’m just going to install them.

Arcenik,
Did you see these upper mounts? I bet you get over an 1.5" more drop!
Remember the mounting point on the shock is inboard of the hub face. They also look like be easier to make.

Those are the xii mounts they will give you about 3/8 more drop. I outlined the mod that would need to be done when ordering from slick and dirty to get the additional 3/8 drop.

Good luck trying to get those though. Xii does not have there coil over kit in stock and the probably have to make the mounts.

Sir,
With the most updo respect! I for one totally respected and praised your work on this‼️
But I will have to disagree with your assumption of the amount of drop that XII top mount will get.
The bolt that goes through the eyelet on the shock is the width of the tubing from the top plate. Yours is approx 3/4" from the top plate. Plus please remember the shock mount is inboard of the hub face. I'm not an engineer and just totally guessing if you get 5/8" at the shock mount will get more drop at the hub maybe up to 3/4" or more?...
Is there anyway you could have your buddies make the top shock mount like the XII? Just asking! :)

Again Thanks!

You are correct that the mount sits offset from the lower mount but the shock is only sitting at a 15 degree angle which is not much. The xii mounts don't sit much higher than the ones that could be ordered from slick and dirty. The fact is you cannot move the mount up much, as you will eventually hit the shock tower base plate with the shock as the shocks needs a 1/2in clearance from the center of eyelet to shock mount plate. You are also correct that moving the shock up 3/8 will net you more that 3/8 of an inch drop. But the difference is negligible 1/8". The diagram below shows 1/2 movement in the shock mount will net you 3/4 at the wheel. You could pay someone to copy the xii mounts if you are looking for the extra 3/16 of an inch or you could order from slick and dirty with the adjusted top mount hole moved 3/8" and net 9/16" lower at the wheel than the original designed bracket.

The measurements were taken off my 2015 at ride height, these are all just rough measurements.

Moving the strut upper mount up 1/2" nets a movement of 3/4" at the lower ball joint.

Not shown
Moving the mount up by 3/8" nets movement of 9/16 at the lower ball joint.

The difference is 3/16 of an inch. But the real difference is being able to get the bracket.

Also remember I pointed out you could order the slick and dirty plates with the mount hole moved on a previous post.

Sorry,
Not trying to start anything just thought it would easier to weld two small dia. pieces of pipe and clearance the top round mounting plate.
As I read earlier that you were thinking about running the shock so the shock adjuster is at the top. That's what I would like myself!
I really do appreciate all your leg work. Another thing I don't like about XII coilovers is they are on heim joints. Don't know if you been in a street car / truck with heim joints on the street but it's ungodly noisy! Gets real old real fast‼️We also had a light weight sand rail when I was many years younger and it ran on heim joints. ( I would drive on the streets when my father would let me ) We were always replacing them because there is no real way to lube them. They are constantly moving thus wearing out.
Oh, if your are ever in the Valley ( i.e. Barrett-Jackson or something ) please look me up as I owe you an adult beverage.

Don't worry I like the input I would of loved to have not overlook the mounting point in the beginning, I would of also liked to of just bought the xii mounting plate. It would of made life a lot easier. As long as you use 1/4 plate for the mounting ring and 1/4 wall DOM tubing you will have the 1/2" clearance you need to make the plate just like the XII, the rest of the measurements are in the thread to have any fabricator make them. I do plan on running the shock inverted I have tested it and it fits good. Actually with the DJM kit you have to run it inverted or it rubs the lower mount.

It also turns out that having the spacing quite large on the upper mount should let me run the DJM kit with the coilovers and achieve a 2.5" drop instead of a 3" which is what I was originally after.

If you order the QA1 coil your self you can specify if you want the helm joint or poly, I ordered mine with a poly joint.

Having the upper mount made(by any fabricator) and buying the shocks and coil's separately you will save quite a bit of money. I think this is the best way to go as everything is in this thread to do it yourself.

Well Just A Little Update From XII On Their Coilover's.
I text XII and finally got a reply last night. I'm 99% sure it was the lady of the company. I asked when they would be selling their coilover's again. They text that the gentleman who was building their upper mounts and brake line mounts had passed away. So they were is looking for the "best of the best" "local to them" :) to build their mounts again and that they had other pressing issues to take care of first. I texted them I was sorry to hear that but, if they couldn't do something right away could I have the drawings for the mounts. To put it nicely that's when the texts started getting a little hmm... short! Long story short I had to ask them to stop. I ended up having to block the number‼️
Yes I know they have two businesses but they shouldn't just blow off XII customers. They are Not McDonald's and they are Not selling the McRib.

Just my.02 cents.

You asked for their drawings? Did you really think they'd just hand you the plans for their mounts? They worked on those for a long time, testing them at track days, breaking them and redesigning them. No smart business person would just give away their plans :confused:.

Yeah I did after they made it clear they were in no rush to produce anything.
Plus they are not the smartest! When they told me they pinch a brake line in their trials, Jesus Christ!
Mount everything but the springs, have someone watch, load the suspension to full compression, turn the wheel from lock to lock, then do the same at full drop. Did the brake line get to close to anything that may cause an issue? If so move it, try again! I should be a rocket scientist don't you think? :)
Besides you know what R&D stands for don't you...? It's Rip-off and Duplicate!
Buddy I'm not trying to be a smart @$$, it's just that they think we have to wait for them and when they are good and ready they will provide their products. Plus we have a gentleman here that's passing out info on DIY!
My father is old and can't build parts like this anymore (Alzheimer's) and doesn't like his kids using his auto body equipment. Plus one day I went to visit and he didn't know who I was. We don't have the room in your garage for this equipment otherwise I would build it myself. And I'm Not a Rocket Scientist. Just an Old Over the hill garbage truck driver. My motto is; The Older I Get The Better I Was. :(

I am going to look into having some new upper plates made to maximize the drop for the qa1 coilovers. The design would be similar to the XII ones.

Would people be interested in these?

I don't want to waste my time, hopefully the price would be around the same as the slick and dirty one.

Yes!
I got a lot of info from Armyoftoo in photos and measurements. Great Guy‼️
Would you like the info forwarded to you?
Their's a lot more detail in the XII upper mounts. The upper mounts looks like they will need water cut, machined and welded.
I was going to a few fabricators I know local but I'm pretty sure they wouldn't be interested in building more than one set.

I would take any measurements and photos you have. I already have the design on paper, I will draw it in AutoCAD tomorrow at work and get a price on the cutting with a water jet this weekend.

The design will use the same plate size, but with a hole cut in the center and DOM tubing for the mount. This is basically the same design as the XII, I can mill the tubing my self and then all I need to do is have it welded.

Sorry to say I'm getting;

The uploaded image is too big. The uploaded file is too large.

So I sent my email address.
We need to thank Armyoftoo for such good info on these mounts!

If you can get all the parts I know some sweet welders and one of the best powder coaters in the Phoenix area.
I'm sure the locals can vouch for AZ Powder Coating!

I think a lot of people would be interested in these now that XII is taking a break. That being said I think some test time should be considered before batching them out for people to buy. This is a part that should it fail could be very dangerous. Should you consider making these available please contact me via PM so we can get you set up here as a vendor.
