Before I got my LCP end links I was using a set of OEM links and I cut off and welded on some new "horseshoes" to the end of the links that were longer and would clear. There's an immense about of force that is on those links at times so if you had longer horseshoe ends they'd need to be really...
yeah, I think you'd see the same issue with any other end links. I have several style links that I was able to compare when I did mine and they all would have fit the same.
Not everyone wants more understeer. Using common sense while driving and not panicking in emergency situations (which may never happen) will help avoid mishaps. But offroad travelling fast, getting the rear to rotate better is a welcome change IMO.
