In the past I've removed the upper control arm snubbers and installed a 3/8" bolt with 2 nuts in its place. Adjust as necessary by changing bolt length and moving the nuts. Currently my theory is just keep stiffening the rebound in the front shock. However now they are full stiff. Had them tightened once already. Going to discus revalving them stiffer yet. I haven't tried limiters in the current car.
