Assemble back into the car. Jack up the control arm and slide the strut into place. Hand tighten the top nuts (not to much, you need play) and hand tighten the lower mounting bolts, being sure to put LocTite 270 or better on them. Tighten the top nuts and then tighten the lower mounting bolts. Take off the bungee cord "brake-holding system".
Put the wheels back on, lower the car.
Tighten everything again once it is back on the ground.
Have your alignment checked.
Enjoy your new Bilstein Sports!!!
