Customized SPL camber and toe lockout plates.
I bought the SPL camber toe lockout kit, only used 4 of the lockout plates for camber, as I had adjustable camber arms.
Rather than using the other 4 centered lockout plates for toe, I had some made on a waterjet cutter, with an offset hole to emulate my present toe bolt position.
I wanted to use adjustable traction arms, but leave them as close to OEM length as possible to avoid changing caster, and causing bump steer.
I just left the alignment shop, and I was no more than 1/4 degree off on toe, and camber, which was adjusted with the camber arm.
No more eccentrics!!
This will work best with a drop using Swift or Eibach springs, no others, as it would be too low.
Im selling an extra set without bolts in the calssifieds.

cool stuff!
some Qs:
1. the point of lock out kit is to get rid of the eccentric bolt and to keep the setting 'locked' in place. it works nicely with the camber arms because the camber can be adjusted on the arm itself. is my reasoning correct? if so then how do you plan on changing the toe with the lockout plate installed (especially interesting because toe changes as camber change) ?
2. a fourth of a degree off toe is quite a bit. are you sure?
3. how come you made your own lockout plates for the toe?

I'm using adjustable "traction" arms, I installed them preset to OEM length.
Toe is in!! Any minimal toe adjustment needed in the future will be done via the traction arms.
I was 1/4 degree off before alignment.
I was so close, just restoring the camber back set the toe to specs.
SPL Traction Arms
I like these so much, I might dump the SPC camber arms for the SPL arms!!

i had no idea adjustable traction arms could adjust toe, if the toe arm (the spring bucket) is kept 'locked out'! this warrants some research on my end.
-
if you can deal with the nvh, mechanical bushings are superior to rubber ones
there isnt too much added nvh with the spl camber arms from what i hear. spl makes quality $hit

I just did the research, between this post, and my other post regarding my alignment specs!!

yea, i needa do a bit more research on adjustable traction arms because i had no idea they can change toe. not trying to argue or anything lol
my initial thinking was, if you lock out your toe then you can't really change your toe (because you only have the oem spring bucket). i thought it was just on spec because you 'locked' it after/during an alignment. my question was, what if you decided you wanted to go 1/8 toe out or 0 toe for driving purposes? i didnt think it was possible. until you stated that the traction arms could change toe. i had no idea and will look it up
thanks for the printout.

I did lock it in after an alignment, installed the arms, and tweaked the settings due to the fact I was slightly off when pre-adjusting the arms.
The traction rods affect toe, and camber, but not much of camber.
The Camber arms affect camber and slight toe but inversely proportionate to the traction rods.
Traction rods:
toe out / negative camber
toe in / positive camber.
Camber arms:
Negative camber / negative toe (toe in)
Positive camber / positive toe. (toe out)
The reason I custom made the lockout plates, is that excessive adjustment to the traction rod, affects rear "caster" for the lack of a better term. Also changes bump steer. I believe stock bump steer goes toe in.
Toe out on rear wheels can be dangerous.
Cars are designed for toe out on turns in the front which matches the turning arc.
IMO, toe out on the rear will push the car. (Oversteer)

gotcha!
quick 2questions tvpostsound, you have the SPC UCAs right? do you think it'll be possible to press out the bushings they come with and 'upgrade' them to delrin or something that wont slide out and cause previously seen bushing failures? i'm sick of waiting for spl's spherical.

Pressing the bushings is certainly possible.
My first set of SPC UCAs had a bushing break down, and slide, they replaced the bushings, and ball joints, rather than sending me new ones. The work order stated pressed in new bushings.
I now have the "new" version from them.
SPL, on the Z boards keep saying "any day now"!!
Speaking of SPL, Im thinking of replacing the SPC camber arm with theirs.
This is a pic from my first set:
