Well yesterday went a little something like this:

Car feels so much more solid now, I think the old stuff was a bit more worn than I was originally thinking. You do hear/feel a bit more, mainly concrete joints, but it isn't uncomfortable at all. Haven't really noticed any difference in the suspension geometry.

Yea the THR cabs are one of the best mods you can do with little to no draw back. The only geometry diff you'll notice (if you can call it geometry) is that the wheel will be farther forward in the wheel well. Everything else is the same. You won't feel much more harshness through your seat, you'll feel it through feedback in the wheel.

I though these had the offset geometry of the M3 style CABs? Meaning more caster and thus more camber under cornering? But yeah agreed about the harshness, just felt through the wheel and heard more so than before. Still feels much more solid through the wheel, it would sort of crash over large bumps before from the worn out parts, now more of a dull thud.

You're not changing the control arm, you're not changing the strut. The THR cabs simply move the control arm a bit. It's offset/rotation which does not change "geometry". I keep using quotes because definitions change based on your definition.

Technically, you're rotating the control arm in the ball socket that attaches to the subframe. This does two things. One, it moves the strut knuckle forward (more caster). but it also shortens the distances perpendicular to the car to the wheel. This GAINS you camber. The caster gives you less camber angle in a corner (well... again, MORE depending on how you look at it) but the shorter arm gives you less dynamic camber as well.

Blah blah blah, so in THAT sense, "geometry" changes. But the control arm still has the same built in angle it always did.

Ahh ok gotcha. Yeah that's what I meant by suspension geometry changing, as your moving points around and changing how parts interact with eachother, even if it is by a pretty minimal amount.

Are those stock arms with aftermarket bushings (the Treehouse logo is obvious) or are they all aftermarket?

Nice bokah BTW.

Stock E30 arms (febi) from Pelican, CAB's obviously are Trehouse Racing eyeball arms.
