New here.
Enjoying my 2021 base model purchased last summer. Wasn’t planning on getting an ILX to be honest but at the time it was the only new car I could find on a dealer lot! A batch came in (grey, black, white, etc.) and they were being test driven and bought up all at once. I claimed the white one for a test drive and by the time we returned to the lot I found all the other ILX s being sold. So I kept the white one.

Over the past year my son has gotten into autocross and after attending a few of his events (his MK7.5 GTI in the pic) I decided to join him. Ran the ILX bone stock at first and now I’m getting around to a few mods.

Car has responded very well to a few simple mods:

Up front;
SPC Camber bolts in the upper holes.
Whiteline adjustable endlinks.

Rear;
Eibach rear sway bar
Whiteline adjustable endlinks
SPC adjustable camber arms
SiriMoto trunk brace

All around;
Eibach Pro Kit springs on stock dampers
-1.7 camber at all four corners
Powerstop Track Day pads (work great for daily driving)

For track/autocross I’m using Kumho V730 in 245/40/17 (great tires).

Car is well balanced and very predictable.

Outstanding!

I have a pretty good feel for sway bar improvements. Pretty base stuff. Tell me about adjustable end links. How necessary is, and what is the gain, from the 'adjustable' part.

I know end links need to be upgraded (heavier duty, serviceable, greasable) with sway bars (most have stiffness settings of their own)...what is the purpose of the end link adjustments?

I notice adjustable end links only on the front.

Explain the logic for me.

When lowering or a car either by springs or coilovers, the proper length of connection between the end of the swaybar and it’s related point of connection (up front, that point of connection is on the strut itself), will be affected. Using a factory length endlink will force the end of the bar, loading it. The bar itself should be unloaded when the car is static and should only carry load during lateral transitions. Therefore the adjustment in length eliminates unwanted preload on the bar by maintaining the end of the bar at its proper geometry.

The pic below describes the connection. These are SiriMoto adjustable. Been meaning to get around to installing these instead of the Whiteline I currently use.

Not explained, or ever read, about any car...

Without spring adjustment or lowering, do aftermarket sways, generally, require adjustable endlinks for correct fitment...for zero load when neutral. (I think i said that right. Ha)

You're right, for sure. Simple logic, i think explained earlier, is if you beef up the sways, OEM end links could, potentially, end up being the weak link. Doesn't hurt to upgrade them too.

With that information, i went to partsgeek.com (or something similar) for my other car and picked up, beefed up, greaseable, non-adjustable end links for around 160 total, for all four corners, rather than dumping two hondos (per pair) on adjustable SPLs that have no use to me.

Thanks gents!
