Do you or do you not need a shorter RTA with a 1- 1.25 drop?

If you drop the car 1.25" with Eibach, pfat, etc. do you need a shorter rear trailing arm to obtain OEM alignment specs?

Also, what are OEM specs and should they be the same after a drop or changed a little to compensate?

Hi verboten,

Thanks for posting your question. Please take a look at our recommended alignment values in this PDF below, it will outline the values you should try to aim for, when using drop springs and/or other components for a variety of uses ranging from full street to dedicated racecar.

You do not need to install aftermarket rear trailing arms to accomplish the "performance street" alignment settings that I have posted below. Take a look and let me know if you have any questions! We are here to help.


min Camber (deg) -0.9
max Camber (deg) -1.1
min Caster (deg) 7.5
min Caster (deg) 8.5
min Toe -1/16"
max Toe 0


min Camber (deg) -0.7
max Camber (deg) -0.9
min Toe -1/16"
max Toe 0

These settings will provide good performance and good tire wear
