@BergmanAutoCraft can set you up with the SPC options. You can also add taller ball joints at the same time with his Howe options.

i thought those were only avail. in big ball joint?
i mean i guess anthing is possible, but i don't think i've ever seen small joint adjustable uppers that weren't full custom. maybe early firm feel?
Sorry, skipped right over the year. Belay my last.
Hotchkis makes a small ball joint version of their arms, #1112-S
They have heims though, which you may not want for the street. And they’re only single adjustable, you have to pull them out of the UCA mounts to adjust the UCA itself.
QA1 also makes a small ball joint tubular UCA, but they’re not adjustable. They do have additional caster already built in though.

jeebus! $450 for the QA1's (plus $65 for their eccentric bolts) for 3 degrees of caster! for $300 mas at least you get adjustable with the hotchkis, even if you have to take them off (makes face).
You shouldn’t need the QA1 eccentric bolts unless your factory ones aren’t any good. And you should be able to achieve more than +3° of caster with the QA1 UCA’s too.

fair point. i figured QA would pull some BS like having specialized bolts to go with the arms because some aspect of them doesn't jive with stock hardware by jussssttttt enough.
Not much they can do there because they still have to use the factory UCA mounts, which dictate the size of the bolts.
The better question is, why the desire for fully adjustable UCA’s while retaining the small ball joints? Since that will likely mean retaining the factory brakes and small bolt pattern, which means probably not running really wide tires, which reduces the need for a fully adjustable UCA anyway.
But if you really wanted fully adjustable and wanted to keep the factory small ball joint spindles, it might be worth reaming those spindles to take a large upper ball joint so you could use the SPC’s.

i was scratching my head on that as well...
the small joint kinda negates the use of an adjustable upper, imo. so then it'd just be to say you have an adjustable upper, i guess?
oof. reaming an upper for the bigger joint. yeah, i'm gonna pass. but that would be the work around to get the killer uppers...
Define "fully adjustable" for us. The factory upper arms are "fully adjustable". They just don't have the range of caster adjustment some of the aftermarket arms do. Do we assume you mean arms with adjustable heim joints? That's gettin mighty fancy for a street car. What are you intentions with the car?
The factory upper a-arms are not adjustble, just the mounting bolt location is. I have -3 degrees of caster as my car is set-up with offset bushings and trying for the most caster.
I am running the factory 4 piston disc set-up & do not want to get rid of that, may just have to ream out the upper mount.
I will check those SPC arms out and I am really curious about the taller bolts, that could really help alleviate some of my caster issue.
We have the SPC arms in three versions. They offer the largest range of adjustment of any arm on the market. Since they don't use eccentrics, the alignment process is much easier than eccentrics ever were. 2 of our SPC arms offer taller ball joints which is a geometry improvement all around. If you are purchasing a different arm for your project, you are misinformed. Make the right choice and shop with a pro and site supporter, not the guys with big ad budgets shoving parts down everyone's throat.

Have you got links/part #'s? I'm contemplating upgrading.
Suspension Parts Archives - Bergman Auto Craft There are 5 pages of suspension parts. Go through each page because the arms are not all on the same page.
It’s hard to believe you are at -3 with offset bushings.
I hope you mean positive caster...I run 7.5 degrees positive like a modern car.
What do you think the control arm mounting bolts adjust? The frame? They most certainly are adjustable.
So you have NEGATIVE 3 degrees caster WITH offset bushings and that's ALL you can get? Are you 100% SURE you installed the busnings the right way? I would double check that. These cars are difficult to get what I would call a "modern" caster setting, that's for sure, but usually with offest bushings, you're looking at 3-4 degrees positive caster. I would surely investigate that.

It is negative caster, I know how to correctly put offset bushings in, I did alignments for several years at a shop & understand suspension geometry. I’m not doing a pro touring lowered car, it’s not at all the ideal set-up, I’ve got fenderwell headers, short 24.75” tall tires & need it taller than stock height.
So you are setting your caster backwards to make clearance between your tire and the header?
Your statement about pro touring lowered cars is a bit ignorant, ya think? ALL of these cars benefit from more caster. Until recently, we just didn't have the parts to achieve modern numbers. An experienced guy like you should know this.
Would having Just One Offset-Bushing in the Rear of the Arm make any sense?
Just to get a Lil bit more offset?

No, I’m am not setting it up for negative caster that would be idiotic, I want 6 degrees of positive & need adjustable a-arms to achieve that which was the purpose of this post.
I'm confused. I read this from your earlier post - It is negative caster, I know how to correctly put offset bushings in, I did alignments for several years at a shop & understand suspension geometry. I’m not doing a pro touring lowered car, it’s not at all the ideal set-up, I’ve got fenderwell headers, short 24.75” tall tires & need it taller than stock height.
I have 3 degrees of negative caster, want 6 degrees of positive caster. Hoping to get it to work with fully adjustable a-arms & taller ball joints should help even more.
Our SPC arms will get you there easily. Both our SPC 1.5 or the 2.0 have taller ball joints as well.
