Shock/Strut Adjustment
Good day
I just install Eibach Pro-Kit Lower Springs (1") and was wondering what setting would be best to set my new Koni shocks/struts. I also installed UMI Performance Pan Bar, RLCA's and LCA's. Thanks, your assistance is appreciated.

Re: Shock/Strut Adjustment
A good starting point is middle on the front & full soft on the rear.
Then experiment... Adjust the front first.
Obviously soft will ride the best, but for handling as you stiffen the shocks turn-in usually improves & the car gets more responsive. Adjustment depends on what you want to do with the car.
For handling, find a long turn where you can repeatedly test the car.
Work slowly & carefully so you do not kill yourself. An offramp is typically a long sweeping turn that you can repeatedly test on.
You essentially have to push the limit until the car starts to slide entering the turn. Try that same speed again with the front shocks slightly stiffer & see if it improves.
If so, increase speed & repeat the above test. Keep going until the car starts to slide then catch on initial turn-in, at this point you are too stiff & back off the setting to verify.
If the car immediately gets worse on the first adjustment, loosen the shocks & repeat working in the softer direction.
The only correct setting is what your car likes... there is no specific setting.
I was lucky on mine, tigtened front 1/4 turn from middle & it improved, added another 1/4 & is started sliding on corner entry.
Went to the rear & tried 1 step stiffer & it got loose.
I was basically done.
