This is NOT the case. The goal is to have the lack of bind via proper phasing. I think we are saying the same thing in different ways.

If each end is in the middle of it's range, the joints will be phased 90 degrees from each other. Ideally, when you twist the link with a wrench as shown in the photos, both will reach their limit at the same time (on each end), in both directions. Lots of interesting solutions to a potentially undersized inner toe link. Marginally undersized at least for track use with slicks. For a less expensive and less complicated solution is there a reason the welded-in fitting in the frame can't be bored 2 mm bigger in diameter?

After a quick examination of the 10 mm inner toe link it would appear that the hole could be bored to a more standard 12 mm. With a 12 mm hole a standard 12 mm heim could be substituted for the 10 mm inner toe link. Mounting the heim with a 2 mm bigger high grade bolt should be much stronger. Add a nylock and locktite to keep the bolt tight. I would think that would at least double the strength of the inner toe link attachment.

Of course once the mounting hole is enlarged a stardard inner toe link can no longer be used if that is important. Any thoughts? For a less expensive and less complicated solution is there a reason the welded-in fitting in the frame can't be bored 2 mm bigger in diameter? I'm not sure about the welded-in fitting part, but the reason that you can't enlarge the hole is that the toe-link mounting bolt also acts as the lower a-arm mounting bolt. The bolt passes through the chassis, the bushing, and the chassis. If you enlarge the hole in the bushing, you would weaken its strength and it might possibly crush under the clamping force, which in turn would loosen the whole assembly and cause fatigue loading on the bolt...

It's not a simple solution...

Unfortunately, the simple solution is to check the torque on the bolts for street driven cars, and for serious track/sticky tire usage, add the brace and Heim joints - but be prepared for frequent replacements of the Heim joints (they won't fail, but they will wear out more frequently).
