^ .. what he said. Sway-bars need to be connected with the car on its wheels on level ground with zero pre-load.

Also, by how much did the camber change as a result of ride-height changing. Camber gain becomes larger the lower the ride-height goes.

Understeer usually comes from the rear if the car was previously well balanced so think about whether have you introduced more rear bar at the rear to impact understeer turning right. Re-measure everything (including toe, camber and caster as well as the corner weights and you should find your problem).

Also check the u-clamps on the front bar to ensure they are holding the poly-bush securely. I have had u/steer in the past as the poly bush "escaped" from the u-clamp (they were also FUBAR and were replaced - this item is now a service part - replaced every 8 events).
