it's always good news/bad news, with progress stalling toward the end

Good news:

Hardware installed. Tank mounted to the CF trunk panels, compressor hidden underneath, only essential lines exposed due to the tank design. The switches look pretty OEM on the center console

Additionally, the cup system provides significant lift, as advertised. It works

Fronts aired down (there is much more adjustment downward on the front coilover, we just didn't mess with it yet):

Aired up, its like 2 inches of height gained

Rear down

Rears up

The bad news, as described before, is specific to me. That rear static position is the lowest it will go, maxed out SPL midlink and a new 5 inch spring. The car's been on a lift so the springs have only been under load for about a day or so - the hope is it will settle a bit, maybe 1/4 - 1/2 inches.

I want the top of the tire to meet the fender, which means . . .

- 4 inch spring, which poses a problem of limited travel and the cup/bucket hitting
- machining the bucket, unknown consequences and cost
- removing the rear cups entirely, which is easiest but dumbest

Great looking install. I’m sure you’ll find a solution that works for you.

Quick and dirty video but…it is done.

Delayed a few days due to a tire blowout but that seems to be resolved

My final solution was a 4 inch height, 2.5 inch diameter, 600lb/ft spring from Eibach

We were able to trim the spring perch without machine work, it was thin enough metal we could take a centimeter or so off the top and that was enough to clear everything on compression

When planning your final height, the stance cup adds MORE than an inch. Their measurements said 30 mm or so but there's no way it was that. It's more like 1.5-2 inches since I had to go down from a 6 to 4 inch spring.

keep that in mind when thinking about where you wanna end up and your rear spring length/suspension parts planning

If you don't care about being stance-low, you will have an easier time than i did

Note what was trimmed on the rear perch
