Checking old episodes of Project Binky for info and measurements, when they moved the rear strut top mounts inwards 20 mm it moved the uppermost knuckle bolt hole inwards 2 mm. They were also helpful enough to show a closeup shot of the rear strut mount with two 25 mm spacers bringing the mount downwards. The angle is fairly steep, so along the 25 mm spacer the top and bottom edge appear to only be a few mm different (when seen from above). Based on that I think I would only need a small amount of rear camber adjustment to bring it back to spec (worst case shaving 0.5mm off the uppermost knuckle bolt hole should do the trick).

Clearance to the strut tower I'm hoping will be okay as I'm pushing all the bulky stuff downwards from where it normally is much more than inwards, but we'll find out.

I got my brakes swapped back to stock and tossed my blown mockup strut in so I could check clearances. A stock GTFour was measured at 14.25" from the fender to hub center so I jacked this up to 15.25" which is what ride height should be with the lift. This is using a baldish 205/50R16, which is a 24.1", tire on a 7th gen rim with an 8 or 10mm spacer behind it, I can't remember which I grabbed. At full compression (bump stop fully squished) there's 1.25" from the tire to the fender lip, I checked full lock at full compression in both directions and there's 1.25" clearance all around except to the rear fender liner at full left lock where it was about 0.75" (this is partly due to the spacer).

As much as I'd like the look of shoving the biggest, most aggressive looking tire I can under there I'll likely go with a 205/55R16 (24.9") so I have loads of space and can borrow spares from my wifes Matrix. Stock is a 23.5" tire so I'll gain 0.7" from the tire and 1" from the lift giving me about 6.8" of ground clearance if the internet is to be believed. That's nearly an inch more than an Impreza and nearly 2 inches more than the BRZ driven by the guy who sets the routes for some of the TSDs here so I should be safe.

Lots of stuff going on so progress slowed down a bit, but last night I managed to rough out the rear spacers. Popping the stock studs out of the rear mount I realized they're smaller than the fronts. I don't feel like hunting down (or waiting for) more parts so I'll just upgrade the rear to the larger studs.

Since I don't have a drill press I bought a cheap drill bit guide to keep the holes straight, it seems to have helped a lot.

You can see the tubes I cut are a hair too long so I'll trim those down when I clean up the poly. The chewed up looking bit in the center is some material I have to remove to clear the angled center portion of the mount.

Thanks guys, I put the rear strut assemblies together so I just need to shorten the tubes and notch the brake line supports (so I don't have to disconnect the lines) and then they can go in. Assembly ran into a few annoyances using front strut inserts in the rear but nothing major.

I shaved down the support tubes and cleaned up the poly plates and assembled the rear struts with the new dampers/isolators/mounts. Lesson learned, when doing stuff like this fit everything to the strut mount *before* you assemble the strut. Otherwise you'll learn one of the studs holes is a hair too loose as you're trying to press-fit the tubes on and go through a bunch of hassle securing it again while trying to avoid disassembling the whole thing.

Anywho, they're together now and I can move on to the fronts. Ignore the oversized nuts, they were just there to save turns pressing the poly on.
