97stanger

Hey guys. I've been asking a lot of questions on upper/lower control arms lately and I have been getting some mixed feedback on aftermarket upper control arms. I already have the steeda aluminum non adjustable lower control arms for my daily driven 97 GT. Now, what are my options here. Should I do the uppers? Or what...some people say yes do them, some say no...im just confused! Any info would be appreciated. I don't run the car at the track, but i'm making some decent power and i need to plant the power to the ground.

I was originally going to go with the Steeda non adjustable aluminum uppers as well...yes or no?

No, a major no. I would recommend reading this thread really quick.

There will be those that say yes, but read that link and come to your own conclusion. I am on the tired end of trying to convince people of how crappy the stock 4 link geommetry is.

i would get adjustable ones only if you are lowered though.

I'm lowered with an Eibach Pro Kit. So, how does something like this look?:

Why would adjustable uppers be cheaper than non adjustable uppers?? That doesn't make sense...

i would go with those to bring your pinion angle back to the factory setting which is usually like -2 degrees i believe. when you lower your car the pinion angle changes which messes up your instant center, and like said above the factory 4 link isnt THAT great so why mess it up even more.

Aereon

Yes, do not mess with it more. The worst thing you can do to your 4 link is increase the rigidity of your uca's and the uca bushings. There is no if ands or buts about it, the stock 4 link is a geommetrical suspension mess.

Sounds good guys, i looked at the thread you posted and some very good info. Makes sense. I'm going to go with those adjustables that i posted. Also thinking of getting a upper/lower torque box reinforce kit which ill get welded. Good idea?

livefast1

i welded torque box reinforcements on mine, with the kit its almost impossible to rip out an upper torque box because its spreads the load throughout such a vast area.

Cool, good to know. I think that will pretty much wrap up my rear suspension then. Here is my list of suspension already done:

KYB AGX 8 way adjustable gas shocks/struts
Eibach Pro Kit
MM Full Length Subframe connectors welded in

Needs to be installed (already have sitting in my room):

MM strut tower brace
MM caster/camber plates
Steeda aluminum non adjustable lower control arms

Going to buy:
Steeda adjustable upper control arms
Torque box reinforce kit welded in


How does that look suspension wise? Anything major i can still look into getting? Keep in mind this isn't a race/trackcar, just a street car.

looks pretty good to me.
