Compression only Upper Link

It looks like it would be there even under a two wheel bump though. Not the end of the world, but depending on its severity I'd think it'd be a little disconcerting. Though, I guess you'd get used to it.

Also, I thought that having lower arms parallel to the ground was generally the goal, as it would pull one side in as much as the other so long as each side was compressing/extending the same amount. I guess the same amounts bit is where it all goes wrong?
In other words, it's rare that each side is moving equal amounts in opposite directions, so roll steer is still around.

Assuming rigid axle housing and rigid chassis, there shouldn't be any issues with straight line braking.

Real world hard braking may result in some off-side wheel hop due to axle tube wrap, especially with light, small diameter tubes.

Braking while the chassis is in roll (trail braking) is another issue. With the top link centered, brake torque reaction is applied more or less equally to both rear springs. Depending on the amount of top link offset, the possibility exists to have more brake anti-squat (or squat, depending on how you look at it) in left turns than in right turns.

Say for example the top link is offset 6" to the right. During right turn trail braking, the chassis is rolled 2" left, and the top link has just passed horizontal. You would begin to see brake anti-squat at the right rear, with no equal effect at the left rear. In a left turn, with equal roll, there would be no anti-squat, as the top link would be downhill to the chassis with the right side compressed.

One thing I can say for sure, from experience, is NEVER angle the top link to the side for any reason. If you have to offset it, make sure it remains parallel to the chassis centerline.

Thanks for all your input guys. I think I am going to run with the 3 link I have setup, throw a watts link at it and move on to other aspects of the car. I will have to see how it goes when I finally get it on the road in a few years
