I have edited two previous posts. The astute among us will have noted it was odd that the wheel to strut distance was significantly different between koni and OEM.
I edited text of another to better describe what the images are of.
Also added several more to understand input from Radman and JHS, and answer the ET25 OEM question.
As ride height changes, TCA angle changes and the wheel move in or out a little.
The least clearance is at full lock, to the inner rear of the inside wheel. 16-17mm on my car as it sits.
Inside wheel at full lock is normally going to have that wheel in droop as the car corners, so the clearance opens up as found in the full droop measurements yesterday.
Where it gets interesting is low cornering G at full lock and 25mm more ride height than my car has. More like OEM ride height. No real droop from chassis roll, but possible input loads from speed humps or crossing a gutter to the driveway. Best I could do with the resources at hand is cross load the full lock position to work the suspension bushes.
As shown in the extra pics on the measurement thread, load and lock with 245 equivalent reduces clearance to minimum.
The inner liner at the front of the car is also close on mine but remember my wheel sits 6mm forward of OEM at swaybar height. For OEM, clearance would increase by that amount allowing ET20 or ET25.
My thoughts are ET20 is a better choice for OEM, to give some room on the inner guard at the rear of the wheel.

Members with ET20 18x9 already continue to disagree with ET25.
I can see that ET20 will fit with the tightest clearance being on the liner across the front. It is flexible plastic and its mounting holes have clearance holes for the mounting screws that allow some adjustment.
As shown in the measurement thread ET25 does not work with coilovers.
As major wheel manufacturers offer 18x9 ET20 for EsCos, one would think they have road tested to settle on that ET. Static measurement is a good starting point but can't beat real road testing.
I think design for ET20 with scope to skim hub face back to ET25 would appeal to the widest group.
I'd be in for 5 off 18x9 ET20 skimable for ET25.

Or does this also require the small
If we decide on this as a group that we all want this, I can finalize the design over the coming week.
