Hi guys,
I am trying to get some review/opinions on the upper and lower Tubular Control Arms from Global West VS CPP.
I would prefer to hear from those who have actually owned or are driving their Tri-5 with these. Both appear to be quality products but there is a huge difference in pricing.
Thank you,
Bob

The Global West arms have had a problem in the past of interfering with a power steering box such as a CPP500 or Borgeson. I don't know if they've addressed this in the more recent past or not.
I do not trust any kind of part from CPP any more.
Consider Heidts.

FWIW, I have a set of CPP lower control arms on my '57 Chevy. During installation I noticed there was no stop for the steering. This concerned me so I called CPP and was told it was not needed. I felt it was so I welded on my own stops, I did not want the steering to have a chance to go over center. I have a set of Global West A arms (upper and lower), on my Studebaker which has a '68 Camaro front clip on it. I am happy with them and they bolted on without any hassle. I know this is not an exact comparison, but I thought I would pass on what I know. I agree there is a big price difference, but I believe in the quality of the Global West products.

Thanks for the reply, yes I noticed that neither the Global West or Or CCP have turning stops welded onto the lower arms.
I also looked at the ones sold by Southwest Performance Products also don’t have this either. I suppose this is something I will need to weld on if needed which isn’t a huge deal.

If the comparisons are close please remember that CPP has been a sponsor of the site for many many years.
Don't forget to mention ChevyTalk if you call.

I went to the Global West website and here is a link to their lower A arms. Check the smaller photos it shows their Adjustable steering stop.

My mistake for overlooking that. Thanks Larry!
It also looks like a really simple modification to add to virtually any set of arms. A spacer tapped with threads welded to the lower and a bolt. Just add additional spacers for adjustment. NICE!

Actually I did a similat thing with my Global West lower A arms on my Camaro front clip. The arms had steering stops, but I wanted a better turning radius. So I cut part of the welded on stop and tapped it so I could put a bolt in there and adjust the turning radius. I got the better turning radius I wanted with no tire rubbing or suspension interference.

I spoke with my son who owns a welding and fabrication shop and he suggested that a tab can be made with a capture for a nut. Much simpler and less powder coat removal.
Simple for adjusting just add spacers or shims behind the bolt.
He recommended using a .50” Stainless lock head bolt. This way no lock washer needed. Simply add a rubber stopper over the hex head. Nice and clean.

I had put upper arms on convertible back when I first built it back in 1983, to get better range for alignment.. I don't recall the brand. But they did wear out.
So, I replaced them with Global West arms, and wow, what a difference. It drives / handles better than it ever did.
I have a CPP 500 power steering unit and it all works together fine.

Hello;
I had the CPP upper and lower arms installed on my 57 almost 4 years ago! The person installing these did only front end work and alignments only on Classic Cars.
At the time I added 2" lowering springs. All has been fine. A bit after, I had the same guy ad a CPP 500 box to the mix and that made the car a joy to drive!!!! And to top that, I installed a CPP (5 years in my garage) Sway Bar, in my driveway and that works wonderful as well!!!
Since I had body and paint and interior, I have not driven the car much but don't seem to have any issues of any kind so far!
Recently, I installed a complete Willwood disc brake system and that has yet to work like I think it should, but I do have brakes but the problem lies in the fact that the rear calipers I got (Caddy Seville) have yet to be adjusted or properly shimmed correctly. Im no brake expert so I guess I gotta find someone that knows the secrets of how the heck these calipers adjusted as well as my emergency brake adjustments!!!!! (everything new, even the ss brake lines!!)

I also installed the Caddy rear disc brakes on my '57. I also had some difficulty getting them to work correctly, but with the help of a tech guy at Right Stuff Detailing, they now work fine. One thing you may already know, is to use the parking brake pretty much every time you drive the car. That action keeps the brakes adjusted and working right. Also proper bleeding is necessary. I suggest you call Right Stuff Detailing and talk to their tech man. Here are a couple of links that might be of help: https://classicbroncos.com/reardiscs.shtml
Also Google: Installing Cadillac El Dorado rear disc brakes on a classic car. lots of info there. in particular: https://www.youtube.com/watch?v=opjdu8DdVeA Good luck, Larry

I just found a third brand that appears to be even more adjustable than either the Global West or the CPP. This is the SPC 97170. They have adjustments for +/- 3 degrees of caster built in plus eliminate the need for shims on the camber with +/-3 degrees of adjustment available.
These replaced their 94350 which required frame modification for clearance. Now having said this the Global West claim to have https://www.spcalignment.com/index.php?option=com_...
Looks pretty interesting. Has anyone installed these?

Yes, I have a set of the earlier SPC upper control arms on my '57. They did not have the newer models when I got mine. I would have preferred the ones in your link, but I have had the older models on my car for a few years now and am happy with them.

Thank you Larry. Well after talking with all the techs and looking at the pros and cons of each I think I am going to bite the bullet and go with the Global West upper and lowers.
Here is my reasoning.
While the SPS does have the advantage of no shims the Caster is limited to 3 degrees and they do not offer a lower set.
The CPP seems to be a really nice set up however the Global West do make a lower that is specifically made for Coilovers plus there is a cutout for both adjustable and double adjustable shocks. Additionally they have moved the bumpstops from the frame to the A-Arm and for a lowered car this is a big deal since I have already destroyed two sets in the past. In addition having the second soft bumpstop on the lower arm eliminates the harsh thud on rough roads during extreme bumps.
I also like the bushings they use and the fact the turning stop is engineered into the Arm for setting this up is a nice touch. It shows they thought of everything. Additionally the ball joints are standard off the shelf items.
Lastly they have done the testing engineering to come up with proper alignment settings specific to their arms so this takes the guess work out to how to set the front end up. Just bring the car to a shop with a 4-wheel alignment shop and give them the alignment specs.
Pricing of the SPS and the Global West are about the same by the time you source a set of lower Arms from some vendor.
I want to thank everyone for their input and I will post the results when I get everything done.

I have a set of Global West upper and lower A arms on my "other" car, (it has a first gen Camaro front clip) and am very happy with them. You won't be disappointed.

Well it's done. I ordered the Global West upper and lower this morning and when I return from this weekend I will do the surgery and upgrades including the new 450 pound front springs. I had a long talk with the QA1 Tech support and with the additional weight I added with the Supercharger and everything else his calculations put me there. I am done with the bouncing from the lighter 350 pound front springs.
