Yeah, I think the SPC UCAs will always have enough adjustment leeway as installed, by just backing off the lock nuts and twisting the fat section marked "SPC"
One of several FAVORITE Kinison spots, out of MANY.
I’d like to see the ones you made. As mentioned before I did not like the look of the SPC because of the small adjusting bolts so I sent them back. I looked at the Hotchkis and they also have small adjusters on them. They may be good for racing and staying on nice blacktop roads but here in Kentucky we have potholes that would swallow a car. I hit a pothole one time so hard in my Charger that it broke/ripped the metal that holds the camber adjusting washers about half way out, the one on the outside inner fender by the shocks. It Immediately started pulling hard to the left. I could just imagine hitting one that hard and it easily braking one of those adjusting bolts. The non adjusting Qa1 are ALOT stronger built because they don’t have those weak points and they have 3* of caster built in them.
I agree that the SPC UCAs don't look like the most rugged, but one issue that I was made aware of by my front suspension alignment mechanic, and if IRC actually 2 different guys, is the lack of adjustment so that's what I focused on.
Wish I had fabricating skills. Those look great!
Do you have that car mini-tubbed?
Not yet, but I have my intention to use the "recently" released AMD wheel well panels, IF that gets me what I need.
Those are huge! I’m running 285 and my car just blows the tires plum off of it. I didnt dyno it. FASTMAN said he guessed it between 580 and 620 hp with my first tune. It’s a 440 I built back when the TF 240 first came out. I actually bought one of the first sets came out. When I’m done with this motor I would like to build around a 500+ stroker with an aftermarket block and still run my T-56 Magnum and do the AMD wheel wells with 330,s out the back.
Allow me, who has tremendous respect for you, your work, your cars, your help on the forum, and so on...
Yes, the rear tires in those pix are very W-I-D-E and MAN! do I like that look, ESPECIALLY on the "Coke bottle" shaped B-Body cars. I have posted (as kindly as I can) that wide tires (no need to be that wide) are mandatory for the 71 and newer Roadrunner/Satellite cars, and although the bumpers on the 71 and newer early 70s Dodge Chargers aren't as obnoxiously huge as the Roadrunners of the same era, they "need" wider than stock tires too, to offset the ENORMOUSLY wide "hips" on those cars.
The geometry needs to be corrected with the steering linkage pivots. Upper arms can only adjust camber and caster. You are correct that all early Mopars have a limited caster range. However adding caster lowers the outer tie rod. Sometimes that helps, sometimes it makes things worse. Outer tie rod location is critical to bump steer. The QA1 rack and pinion stuff has a horible outer tie rod location. Trust me the stock stuff is very good. Even strong enough for "big wheelies". 2.5 degrees of caster is plenty stable at 150. My experience? 35+ years of racing. Probably 5000 alignments thru my carrer. Along with body shop wreck repair
That is another potential issue with the upcoming 572. I have a system that may help prevent lifting the front wheels off the ground, the HitMaster launch control that slips the clutch according to how it's adjusted for amount of engagement over an adjustable time, but that's meant to consistently transfer the greatest amount of power without spinning the tires excessively and not smoking the clutch.

Nitto has my tires 285/40r17 listed as 11.42 inches wide and their 315/35 listed as 12.60. I’m also running a 9” rim with 5” backspacing and I have room for a bigger tire. I’m going to take a measurement today to see if they are actually that wide.
Diving back into the Ackerman part of this, it would appear that Ackerman angle is not even a possibility in a front steer setup given the wheel and tire combos most of us run. And, to make matters worse, you get the opposite effect with front steer. Dare I call it Anti-Ackerman? Lol. I haven’t noticed the lack of Ackerman or Anti-Ackerman as much of an issue in my case since I’m a drag racer, but for those of you who are corner carvers, I think it’s a HUGE consideration.
There have been a few changes, lol. After owning a couple black cars, I decided against it for upkeep reasons. Besides, the blackout look is somewhat played out. It’ll be Petty Blue now. I picked up twin 88mm Forced Induction turbos which should be a substantial step up from the twin 76s I’m running now. The hemi is done and running in my green car at 540 cubic inches with the Precisions. . It’ll get a new cam when I move it over into the Superbird.
