SPC A-arms.

[dlouie87]

I'm looking at some of their upper control arms. Any one have experience with these?



I talked to mark @ savitske for about a hour today about suspension. Great guy with TONS of info.

Trying to put a front suspension together. any suggestion on coilovers/shock combos?

Do a search several people here are using his stuff. If I had the cash I would do stage 2 plus kit with varishock coil overs and SPC lowers. Using what ever sway bar and spring rates Marc suggest.

[BonzoHansen]

I use them. What is not to love. Get the hex adjusters (the 'light' version I guess). And use anti-seize, someone just posted recently about problems,. but they didn't use anti-seize.

I have SC&C suspension on my GTO. See link in my sig to the build thread. Great products and great service from Mark!

I love the SPC arms on my El Camino. I have the steel ones and they weren't hard to adjust, but the hex ones would be a breeze.

[JChilders]

I plan on ordering them next week.

They're on mine. Ditto on what everyone else says. ALSO - if you get the "Race" or "Lite" versions, take off the cross bar first and paint it then carefully reassemble. Good stuff!

Just a note on the SPC lowers, the powder coating finish isn't really that good. The arms have already started rusting, especially in the joints/welds. This is after a year on a car that haven't even seen the road yet. And it's been stored in a dry garage since I bought them. I would probably look elsewere for lowers if I were to do it again, but the uppers seem great (no actual driving yet though).

What is this anti-seize you guys are talking about? What happens if it's not used and what kind of anti-seize are you using?

[shep]

The metal threads of the plates will gaull (sp) up on the aluminum and will seize. The anti-seize will help prevent it.

I am very happy with mine. only thing I can complain about is the cross shaft rusted up pretty quickly. I would have them powdercoated if I could go back.

Performance wise they are awesome.

[BonzoHansen]

Yeah, they are bare metal. I took mine apart and painted them (see #3 above)

IMO:

Pros of these arms:
-Price
-Adjustability (no need for shims!)

Cons:
-Ball join plate has a metric bolt pattern so you have to drill it out if you want to use a quality Fbody ball joint that has 5/16 bolts. I didn't want to drill on my brand new part so I installed off the shelf autozone BJ's with the 1/4 bolts they came with and they broke recently after just under 3k miles. I've since drilled the plate to fit 5/16 bolts using the SAE pattern.
-No bump stop for full suspension droop

IMO:

-Ball join plate has a metric bolt pattern so you have to drill it out if you want to use a quality Fbody ball joint that has 5/16 bolts.

Or you could just use the even far far far better quality Howe ball joints, which simply install.

I have some SPC upper arms and cross shafts. I have the race cross shafts (metal bushings), I painted them, they need to be. Just be careful and mask it well. Prime and paint. They wont rust.

As for the ball joint plate and what ball joints you can use its up to YOU. You can use whatever you want. Its basically ala carte. You can pick yer ball joint plate and use it with the arms that you need.

Download the catalog and get the part numbers. Any of the dealers here will get you great dealer pricing. JR

Well re: the BJ plate I bought them from Mark at SCandC so I would assume if they make an SAE pattern that fits the std 1st gen Camaro bolt pattern he would of supplied it that way.

Of course I did just make an "assumption" heh

[wmhjr]

I think maybe the reason Mark ships the arms with those plates is that I'd guess more than 90% of every one he sells gets built with Howe ball joints. Just a guess, but....

[CRead01]

I got mine from sc&c with the tall ball joints from Howe. The ball joints are quite nice and worth the extra coin.

[79T/Aman]

there is no such thing as a metric bolt patern on the upper ball joints F-body 1st &2nd, A-body, G-body all use the same patern, the trouble is with the ball joint patern is not to spec (very common), some ball joints have sloted holes to solve the problem, drill out the ball joint holes if need be.

[Chad-1stGen]

I'm referring to the ball joint plate, not the BJ's on a first gen.

I was visiting my home town when I had the upper BJ problem so I had my friend who owns a repair shop do the work. He is the one that did the measurements and called SPC or a vendor that resulted in him telling me it's a metric pattern on the SPC plates I got from Mark.
