New height-adjustable, quick-ratio CNC'd steering arm project is done. Finally another item I can cross of my list. Still need to take em to the anodizer next week along with the strut tubes and upper coilover spring perches to have the aluminum parts hard anodized red and the strut tubes plated in electroless nickel.
This pic is a close-up bottom view of the arms. Total weight with hardware 12.02 ozs per arm. I opted to keep some weight rather then lighten them too much and risk bending one. These should be a little stronger than stock at about 2/3 the weight.
The further-most hole (with red solid oval dot in pic) from the strut bore is where the thru-bolt for the extreme heavy duty spherical bearings with teflon liners will go. I milled a stepped relief so I can turn a hardened steel shouldered bolt pilot bushing up on the lathe and press it into top/bottom sides of each arm. That way no steel used in the spherical bearing bolt or upper/lower washers will ever touch or wear against the aluminum pilot bores or upper/lower arm surfaces. You can see a thumbnail sketch of what the shouldered bushings will look like and they will be pressed into the arms after anodizing.

Pic 2: saddle bolt clamping shell (top view)

This shows how the arm is tightened to the strut tubes. Once loosened I can move them 7/8" higher than stock or all the way down on to the hub flange tops or anywhere in between... infinate height adjustability between those limits.. Bye-bye bump steer and hello to properly adjusted tie rod geometry no matter how much I raise/lower the car.

CQ rear large diameter rear strut converted to B4Q front strut in foreground with new steering arm compared to stock B4Q small diameter strut with stock spring perch and steering arm.
