Option 1 : install SPC uppers and the no bind ball joints, sell the Global Wests.

Option 2 : sell the SPC uppers and no bind ball joints, buy the del alum bushings ($150) and the 2 billet shafts (63$ each)

(my setup includes AFX spindles and I will get the GW lowers later on)

What would you do ?

This is a no brainer, go with the SPC uppers. Even though they don't have the Del-a-lum bushings they still have far superior adjustability not to mention they don't require shims. Not to mention they are lighter. Sell the Global west arms and never look back.

The global west stuff is defenetly top notch as far as quality goes. Not that the SPC stuff is bad but you can really see the quality og the GW arms when you hold them. I cant wait to get my global west lowers :D

Why would you sell fully adjustable,race proven arms that are lighter in weight and have simply the best ball joints available anywhere in favor of non adj. arms that are heavier than stock and have cheap parts store ball joints? Seems like a no brainer to me but I admit it`s possible that I could be slightly biased. :thumbsup: Mark SC&C

I've got Global West upper & lowers on my '70.
Just yesterday installed the SPC Stage 2+ kit on my '66. I must say, I'm VERY impressed with this product!!
Can't wait to get it on the Alignment rack. :thumbsup: Thanks Mark.

We`re always glad to help guys. :yes: The lower arms are coming soon. We`re on the 2nd set of prototypes and we`re really close. Engineering analysis is ongoing and the CNC programs for the water jet and such are beign done now. This is gonna be a pretty big deal,the very first tubular lower arms that actually improve performance and geometry over stock ones! I can promise they`ll be worth the wait. :thumbsup: Mark SC&C

Will the lower arms be available with a double sheer mount for coil over setup... I'm working with Tyler at ATS on my fornt suspension and he said he was going to have to modify some GW lowers.... maybe you can work together.... make a production piece.... He uses some Bilstein ASN coil overs ... and he wants to use my 67 to design a double sheer top mount.... I already have your upper arms and the ATS spindles....

Early spring,we plan to have all the fitment and testing etc. done well before the show season starts. At least that`s the plan. ;)

They have a modular lower seat. The std. coil spring version will incorperate shims under the seat for ride height adjustments and we`ve already got plans to do a double shear coilover mount. We`ll also be offering a double shear upper mount for those who want that style,either ATS or our own. ATS is supposed to get back to me with specs for the coilovers they use so we can offer a lower priced Varishock alternative too. Mark SC&C

What type of LCA bushing will be used ?

The shocks that ATS showed me were Bilstein ASN series. B46-ATAL5 with special valving....
Here is the link to the .pdf catalog with some specs...

Do you have any more details on the upper double sheer mount? I found some pics on the web of a 64 but they extensivly modified the frame... Beyond what was needed to runcoilovers

Disregard this post, I found an update here: http://www.chevelles.com/forums/showthread.php?t=171388
Mark,

As you know, my Eradispeed rotors and red C-5 Baer calipers are due for shipment out from your shop near the end of April. I have been watching some of the posts but had a momentary lapse of PC use as my home computer went down.

I am interested in eventually migrating away from the GW (UCA & LCA) and possibly the QA stuff. I have to agree whole-heartedly with some of the posts I've read here, the front QA "coil-over" shocks have a lot of side force on them. In fact when I mounted my QA-1's I had to add shims under one side of the lower shock mounting bolt to get the top of the shock rod to align without persuasion with the upper mounting hole in the frame!

I do have ATS AFX spindles and arms and would like to know if you can update us on the progress of the new lower arms for the A Body. Also, what type of Varishock will fit with the intended design?

Sam

How strong are the SPC arms compared to G West arms.This would be for a street application that gets beat on pretty hard. I know they are heavier but the ones from Global are stout.

Having handled both I would say that the GW stuff appears and feels much stronger that than the SPC arms. It's also a lot heavier. But I am pretty sure the SPC stuff is plenty strong to handle street duty.


Maybe other will chime in on this.

The adjustability of the SPC arms makes them hands down 10x better than the global west. Keyword no more shims. Also, the loads applied to an upper arm are minimal since all it is required to do is locate the spindle not support the spring load.
true true...
