Hey all, finally, my lift kit is completed, my CNC work is done, and my kit is installed. More pics to be added soon.

2.2" total lift.
12116


Lift kit installed by me...
FRONT (2.2"):
1/2" Subtle Solutions top hat spacers
1.7" Eibach Lifting Springs
Nameless strut tower brace

REAR (2.2"):
1" Anderson Design and Fabrication top hat spacers
1.4" Eibach Lifting Springs
1" subframe spacers designed and CNC'd by me

OTHER:
Primitive Racing skids (front, front lip, mid armor, rear diff)


Alignment came out great, so, my math worked out right. Everything worked out within range, and, exactly as expected. My rear is loaded down for the trip, because I wanted to see if I was still in spec (yes, -1.0° in a range of +0.3° to -1.3°).

Very nice setup, Robert!

The one question that comes to my mind is how has this affected your total suspension travel/articulation?

"The one question that comes to my mind is how has this affected your total suspension travel/articulation?"

Total travel (strut/shock) (fully compressed to fully uncompressed) is unaffected, but, full compression requires more force. That's something I was looking for, since (though the pics hardly show it), I do some extreme stuff where the Ascent will have 90-100% of its weight on only two wheels, thus compressing the heck out of two corners. It's a thing, for me, lol. I like doing shots like that (or having someone else get the pic), so, I look for places to lift wheels or compress the suspension to portray motion.

Thus, it's nothing special (or even a good thing) - I just tend to do it more than most people, because I intentionally do it, a lot, for photos and vids, lol!!!

...like this:

Most of the weight is on pass rear and driver front in this shot
12118


I am about 10 pounds (on the pass front corner) from being on two wheels here (hence the driver's rear is unloaded and driver's front is shoved really high, and pass front is in the air). I literally lifted the driver's rear by lightly pressing the passenger front.
12119



Also, I do a LOT of transitioning from four to two wheels and back, like in these in-motion shots.
12120

12121


Since the struts and shocks only go to a certain length, regardless of my changes, max travel in relation to suspension is 1/2" more in the front, and 0" (zero) in the rear (subframe spacers of 1" canceling out the 1" top hat increase in bottom travel. Thus, I've nearly eliminated excess articulation on the CV joints (no more than 1/2" extra on front, and no changes in the rear).

Anyways, my needs may or may not be the same as others. Doing top hat spacers, and doing springs, and doing subframe spacers is probably the hardest mechanical method of lifting an Ascent, since it deals with everything. It was much easier to just do one thing, lol!

Ironically...
I know how well the Ascent balances on corners, and loads weight, so, I figured out a ridiculously easy way to install the frame spacers. It took 30 minutes to drop the entire subframe and its support brackets, and the sway bar mount, and install the spacers. Start to finish. And that included lots of pauses to film chunks of it for the 2nd and only other Ascent that will get this lift. That was the absolute easiest part of the job. I don't recommend my method, because a mistake can destroy the car. Literally. Unibody, gas tank, axles, you name it... but if someone is very mechanically inclined, I am sure they can figure out what I did.

@Robert.Mauro Nice work.

Personally, I have no off-road aspirations and the Ascent's on-road agility is right about my minimal, but nice to see what others can do.

Question: in the Drive article on Wilderness Outback, they mention that Eyesight needed to be re-programmed for the additional ride height. Have you seen any issues or have plans for Eyesight adjustments?

Alas, I cannot adjust Eyesight. It's programming changes that need to be made. Yes, Eyesight, especially things like Lane Centering and Lane Keep Assist, are affected. I am sure pre-collision braking is also affected (and thus adaptive cruise control) because of how closing distances are affected by the changes in angles and distances when approaching at the same speed.

This makes me wonder how affected Eyesight is to changes in attitude from less aggressive "modifications" such as rear squat caused by tongue weight and cargo loading.

Would adding front proximity sensors and radar make Eyesight reprogramming unnecessary?

In the many Eyesight warnings, these are noted as having impacts to system performance:
  • When towing a trailer or another vehicle, etc.
  • A heavy cargo is loaded onto or inside the vehicle.
  • The maximum number of occupants is exceeded.
  • The suspension has been modified (including a genuine SUBARU suspension that has been modified).

Yep! Most people think that's just legalese, but, it's actually engineering fact. Until these systems can process these things like a human brain, things like differing angles and differing heights will affect how they "perceive" the world around them.

To me it reads like the lawyers and engineers had one too many meetings. I know there's a lot of fact in there, but it also says "Do not install any wiper blades other than genuine SUBARU wiper blades. Doing so may affect the stereo camera’s field of view and could prevent the EyeSight system from functioning properly."

That's old, and largely due to the fad of oversized, flashy, glitzy, and sometimes lit up wiper blades. I think we're stuck with it, because there's still those who do it - like the STI that passed me on the Cross Bronx Expressway a while back. Whole car, ground effects, wheel wells, body, wipers and all, were lit up and glitzed and flashing. Of course, (1) he waved, honked and flashed hi, so I'm happy, and (2) STI's don't have Eyesight, so it doesn't matter - but it does for the rest of us who do have it, lol!

No, not really. Nothing different than stock feel in that respect. Everything remains pretty straight on the Ascent because it doesn't have frame spacers like the Outback, Crosstrek and Forester (well, mine does now, but the same size as the Outback's stock ones).

That info confirms to me the main cause of "the wobble" on a newer vehicle is rear subframe spacers that come with most lifts. Spacing doen the rear subframe mis-matches the rear differential and transmission output pinion angles. This one one reason why the Ascent doesn't seem to suffer as much. As CVT mounts and CV axles age, I wonder it will be more pronounced as folks buy used Ascents and lift them after significant mileage. I am always in search of feedback as I continually work on R&D and product refinement.

I'll back you up! It's the best way of navigating over the perils of such roads. 😂
