Icon Extended Travel and SPC UCA Installed this weekend

So I finally got around to putting on some Extended Travel Icons and LR UCA's and got an alignment this weekend and now im rubbing so much more that my previous setup. I notice it a lot more when im driving around going into driveways and especially when I took it out on a short fire road run.

My old setup was Bilstein 5100s' and 885 coils with the factory UCA.

I was rubbing, but not nearly as much as this current setup. My wheels would barely touch the cab mount at full stuff. Now its hitting the cab mount significantly, the pinch weld and the fender flare.
My tire size is 285/75 16

My alignment specs are:

Left Front: Right Front:
Camber: -0.1 Camber: -0.6
Caster : 2.3 Caster: 2.4
Toe : 0.10 Toe: 0.08

Im not too worried about a CMC or some trimming. I just think this is really weird that its made this big of a difference. Maybe the alignment specs are off?

 

If you increase the caster on both sides it will move the wheels closer to the front bumper and away from the cab mount area.

 

Would I be able to adjust the caster on the uca without causing too much change to the camber?

 

In theory, yes. But how far forward you can get the wheels to go depends on how much adjustment you have left in the LCA eccentric bolts.

I would be willing to accept a bit of camber shift if it meant that my wheels would move far enough to eliminate most of the rubbing I was experiencing. And as long as the camber ends up even (side to side)

It's sort of a balancing act. You would need someone doing the alignment that understands the relationship of all the different angles and enough to know what you are trying to achieve. Not just a guy that's trying to make all of the bars on the screen turn green.

 

That's much harder to achieve than anything else.

 

To move the wheel forward in the wheel well, the rearward LCA eccentric bolt needs to push the arm OUT away from the truck and the front LCA bolt to needs to pull the arm IN toward the truck.

Then rough in the toe setting.

Then use the adjustment on the LR UCA to get the camber and caster specs where you want them.

Then do your final toe setiing.

The more you mess with caster and camber the more time it takes. So expect a shop to charge more labor for all the extra time invested.

They are out there but they're tough to find.

I've only been a professional tech since 2005, but in that time I've met one guy in a dealership other than myself that knows WTF we are talking about here in this thread.

If you are looking for something other than a cookie-cutter alignment, look for a speed shop that has a real race car, actually runs it on a track and has their own alignment machine. They'll definitely cost more than Firestone but you'll also be getting a much different product for your coin.

 

There isn't much in the way around here that I've found that can perform a proper alignment. There is a place in Deer Park that I use because they'll get the alignment to my specifications, but as far as figuring out atypical situations like with my aftermarket UCA's, they're no different than anyone else. Seems they couldn't wrap their heads around how to properly align either of my Tacomas because the UCA on both trucks has about 2.7-3.0 degrees of caster built in.

Hell, I'll pay you lol.

 

While I would love to do it, the machine at my shop is from the mid 1980's and originally purchased to work on VWs. It's the kind that you have to make all of the adjustments while sitting on your knees. I put my DCSB Tacoma on it and it was so small I barely had enough length to do the rolling compensation procedure. In the end it did work, but its painful to work with. And to be honest, the thing is so old, I don't really trust the accuracy of it any further than I can throw it.

 

yeah gotta find an alignment only shop. I have a guy in my area, 90 bucks and he knows what he is doing, been doing it for 25+ years. I brought my truck in and he went, oh yeah spc arms, looks like 5100s, what you have em set at? the 1.75in setting? I went yup yup. He goes no problem seen similar many a time before. He then spent 2 hours DIALING it in, im talking within 0.03* per side on each setting.


But yes OP, you could move the wheel forward with the LCA, then get the caster n camber settings you want pretty easy out of the SPC arm.

 

Thanks for all the replies. Ill call around a few shops pretty much doing phone interviews today asking them about these things.

 

I have the same setup, but my tires are 265/70/17. I moved my caster up between 3.8 and 4.0. it ended up driving like a shopping cart with the one front wheel slapping back and fourth. Just to note, they alignment shop was nothing special. Just a local old skool cat. I bet a race shop could of got that wobble oit
