It is very expensive to buy some adjustable strut mounts. Like $280 ish. IMO, they are worth it, however I see you bought tokico HP's and looks like you were trying to upgrade while staying "economic". To get even 1 degree of neg camber out of the adj ones is worth it IMO especially with you going as low as you will be with those sportlines. For that low of a drop, you will probably want a bump steer kit, but if you aren't into spending anymore money just be careful when you hit bumps.
LCA install is a joke. Only recommendation is to do one side at a time so you don't fight the axle too much when you line it up. As far as the adj PHB, do it after you put your springs on so you can measure your axle shift from the sport lines being installed. Take measurements of of your "wheel to fenderwell" before spring install. Install springs. Measure the shift. Set adj PHB to length of stock and then adjust it to the exact difference in the measurements. Install PHB, adjust it if it is still off. If you don't want to do all that, you can just adjust the PHB to stock length, install it and then adjust via the eyeball and there is nothing wrong with that.
Ford recommends getting new fasteners for the intsall. I would, at a minimum, get new strut bolts and nuts. Blue loctite everything.
On all the bolts that need to be torqued, I woul recommend using a red marker or something that you can draw a strip across the bolt and onto the metal of whatever the bolt is being clamped too. That way you can verify if the torque ever breaks or if it has moved.
Follow instructions and don't kill yourself by undoing the top mount bolts without the use of a spring compressor...or I believe you can just jack up the front lower control arm to compress the spring, undo the top mount bolts of the struts and then let the jack out slowly.
You will need an alignment after the front springs are installed. Don't forget to get a feel for the car's new setup before going bonkers...ie, watch out for bumpsteer.
I don't usually preach bumpsteer a lot and I have never experienced it, but then again I have never went "Eibach Sportline low". |
