FRONT STOCK SWAYS are 26.5mm / 416 pounds per square inch

Eibach FRONT Sways are 32mm OD hollow tube with red color finished.
1st setting is 730 pounds per square inch
2nd setting is 900 pounds per square inch


REAR STOCK SWAYS are 24.3mm / 374 pounds per square inch

EIBACH REAR SWAYS are 29mm OD hollow tube with red color finished.
1st setting is 627 pounds per square inch
2nd setting is 741 pounds per square inch
3rd setting is 860 pounds per square inch

Mine is set for 1st setting on the front and 2nd setting on the rear.

Can anyone help me out with how the settings on the sway bars effect the car's handling? ie: stiffer in the front cause more oversteer or undetsteer, same for the rear - also, not tracking the car, just spirited road driving at best. Doing The Dragon in April, what would be a good setting for a good run (not overly aggressive)? Thanks - Best responses get Rep! :tiphat:

Hello, everyone. I'm new to the group AND new to tuning. I have a 2010 Z roadster 6MT with sport pkg. I want to have the Eibach pro-plus kit (springs and sways) installed. I've called a local shop to price part/installation and, of course, plan to call more. The first shop that I called told me that I MUST install the front/rear camber arms when adding the kit. This sounds like absolute bull to me but, as I said, I'm new to tuning. Is this guy right or is he just trying to get more of my money?

Thanks, Paul. I appreciate the speedy reply. I know all of the basics that you gave, but my question is: Does this particular kit, which lowers the car 1.00"–1.50", create enough negative camber to make the new camber arms necessary/mandatory? I was hoping that someone who has experience with this kit could give me a heads up.

The stiffer the front bar is set the more understeer you will notice. Use the adjustment holes closer to the center for a stiffer rate. The outer holes will allow more flex and make the rate softer.

Depending on your set up, driving style and driving conditions, I would set up the car for understeer with a stiffer front setting first and softer rear setting. This will allow you to get used to the car without having too drastic of a change. You can increase the rear rate and decrease the front rate if you feel you need the car to rotate more.
