You really can’t copy someone else’s swaybar setting unless their car is known to be set up properly and everything regarding their suspension (tires, tire press, shocks, spring rates, alignment, etc) is EXACTLY the same as your car. All these items change the adjustments you would make on your sways. The ONLY way to properly set your sways through testing. The easiest way is to set up a skidpad or throttle-steer circle. Find a big patch of asphalt and see how your car behaves, and then adjust the sways according to the general instructions posted here.
