Lucky for me, a good chunk of the problems described in those links don't apply to me since I have the JIC Cross suspension and my suspension is adjusted so I'm not sitting on bump stops (or hitting them as far as I know).
Leading evidence: 'Adjust so i'm not sitting' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Adjust so i'm not sitting' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
ERP makes toe arms both front and rear that use spacers at the wheel carriers to correct geometry to minimize bump steer on a lowered car.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My C4S is lowered quite a bit (under 25" ground to fender with 19" wheels). As a side effect of this, I'm noticing a significant increase in bump steer. I've always had my cars lowered quite a bit, but this is the first car that I've experienced such a noticeable increase in bump steer with. I did a few searches, but none of the threads I found were very helpful.
After consulting the mighty Google, I did find that a few companies make extended tie rods for these cars (Tarett, GMG, Stomski). Does anyone here have any experience with any of these products? Did they help enough to make them worth the ~$500 investment?
Besides the tie rods, are there other ways I can help reduce the bump steer? I have adjustable camber/caster plates and adjustable sway bar end links up front so most of the suspension geometry can be adjusted.
And no, raising the car is not an option.
My bump steer improved dramatically when I went to the X73 setup. You've got a lot more going on with you suspension than I do however.
Are you sure it isn't related to the 19" wheels?
Awesome links, thanks. Lucky for me, a good chunk of the problems described in those links don't apply to me since I have the JIC Cross suspension and my suspension is adjusted so I'm not sitting on bump stops (or hitting them as far as I know).
I did see a mention of shimming the steering rack to lower it a bit, so I may look into that as well.
How did you manage to lower the car and Raise the rack? Isn't the rack attached to the "frame"? Maybe spacers to raise the rack?

or tie rod ends that drop the tie rod ends:

Whichever way you decide to go the rack and tie rod ends need to be in a straight, horizontal line with car "at rest" on the ground.
ERP makes toe arms both front and rear that use spacers at the wheel carriers to correct geometry to minimize bump steer on a lowered car. I've got them front and rear on my GT3
The mounting locations on the regular 996 cars are not very forgiving when you get them pretty low creating alot of toe movement as the suspension goes through it's range of motion. You won't get it all out but you will be able to make it more manageable with the ERP links.
That was one solution until I did a quick image search and realized the way the rack is mounted doesn't allow it to be spaced like that, so that option is out.
From my understanding its a Action or tendency of a car steering itself when the Suspension Travels when going over a Bump or Uneven Surface on the Road. I guess its more promenint in lowered cars.
Am i correct?
