here is a shot of how low the lca brackets are, which really are not that low, my car will be one of the lower cars with the 3 link in it and there is plenty of room, this kit can be installed in the same amount of time or less then a set of mini tubs with closeouts,
think about it, when one side of an axle goes into bump, it wants to go up and in towards the center of the car, so imagine the axle trying to do this with a 4 link whether it has swivels or not, it will bind, the swivels help it but the uper link just will not let the axle move smoothly, now think about it with a 3 link, it as good as it gets with a stick axle,
this is a shot of clearance, althought he car looks high the roof is 49 inches off the ground, and theres 6 inches to 5 inches the bottom of the rear end.
