I have the SPC front camber arms and with this kit not only can you adjust the cambers but also the caster. My question is does the caster have to be even on both sides. The tech said the left is suppose to be .5 degree less than the right. Mine is 7.8 L and 8.1 R Any input would be great thanks.

 

Generally you want the caster to be as even as possible on both sides. This is to prevent the car pulling towards one side. Before I installed my SPC a-arms my front caster was off by .9 from side to side which is a lot. My car would tend to veer to the left. After I installed the SPC arms and made the adjustments the caster was almost even and the pull went away.

 

My car tends to pull to the right...I'll go ahead and make the adjustment on thursday. Hopefully this will solve the problem.
