Washers probably won't offset it enough. And it it's easy to simulate since you would have to basically compress the strut...
I'd say you need probably little more than that. It would be good to hear what Steeda says about it - while the link itself is good (and IMO superior to BMRs - not trying to start a war of both companies here but I've had corrosion all over BMR's - BMR has the same issue btw - they're just too thick on the ends), making it fit for all geometries and all sway bar settings hasn't been truly figured out.so a slip-on shim of about 6mm thickness would do the trick, yes? Paging Steeda Engineering...
I would personally design it differently. Fully support the rod-end at either end with a thinner neck of about 1" length and also make it NOT adjustable. Length adjustment would be done in the *middle* of the span. I also don't understand why you wouldn't just use round bar instead of hex bar for this part. The stock unit might as well be made of spaghetti and is cheap-sh*t cast. The replacement made of 1/2" round bar would be vastly stronger on that alone.
- thank you for the support!
