Not sure where Mark came from in the previous post. Autocorrect I guess.....
I went back to my build thread on MadMechanics and saw that all my old pics in the build process I did we're not transferred over during one of Ari's server moves.
I did get the drawings I made for how I built the control arms though. Below. The rears were very easy to build really. I agree with Bloozberry and his analysis of the geometry changes when extending but I wasn't planning on doing heavy driving with this vehicle so I was ok with the extended control arms vs redesigning the rear suspension.
I was looking for $600 for the control arms, shock tower to hub extensions and axles. Axles alone were over $500 when I got them and they are guaranteed up to 400hp by the builder.
A quick description of what I did.
Mount hub to wheel and place in the wheel well where you want it.
Measure from a known reference point, like front control arm mount point from frame to hub ball joint mount
Get both the the distance along the frame from known point and distance out to the hub.
Lay out the frame mount points and hub ball joint location on a flat surface and then start constructing the control arm to connect the three points. I used 1.25 tubing and also adjustable pivots so I could adjust final location in wheel well.
I also moved my strut tower mount outward toward the upper frame so I would retain the stock geometry of the strut movement as much as possible.
This what I have done on my suspension widening and, again, it is not hard to do. Just make sure you get the control arms welded by a pro if you are not really good at it as well. I had all my welding done by a local welder as my life is worth more than a few bucks.....
