They're gonna be cool.......

Those puppies are mine.

Will have a full build album on my fb page

[Bryce]

awesome!

[19,69camaro]

Any drop designed in them and can steering arms be welded or bolted? Looks great btw.

[dontlifttoshift]

Common aftermarket steering arms from the companies that are using a stock upright will bolt on. A dropped version would be cool, wouldn't it.......

I'm sure you don't know yet, but like everyone wants to know........PRICE?? :G-Dub: :computer:

[Jay@GMR]

YES, we also have a 1" drop version. And as Donny (below) has mentioned, ANY steering arm that currently bolts to an OEM C5/6 Upright/Steering Knuckle will work with ours. We also offer a "weld on" steering arm version that mimicks the stock C5/6 steering location for the actual "Corvette Guys" (basically a direct bolt on in every way)

Too funny Donny! :D

It's not in stone yet, but will most likely mimick those fancy Billet ones like Ron in SoCal sports :G-Dub: These puppies will be in the fixture tomorrow, with a tig rod poking them!

We are happy to be the first to offer a fabricated, chromoly plate, tig welded C5/6 Upright for the aftermarket. This is the ultimate in rigidity.... even at elevated temperatures....

[JasonElvisHeard]

Before I go into the details on the uprights I need to explain and showcase the experience I have with welded uprights and how they are built effectively. One of the most important elements to the construction of uprights is the fixture, and how it is built. Below is a picture of a Trophy Truck upright I built about 6 years ago, notice the fixture and main plate they are bolted to, they are all steel.

http://thegmr.com/wp-content/uploads/2013/02/tt-uprights-from-gmr-shop.jpg

It is important to use Steel for the construction of your upright welding fixture, you need to combat the movement of your material during the welding process and using steel is the best way to combat this. The fixture will be extremely hot during the welding process and if you were to use aluminum then the fixture will move due to the welding heat. This is why the use of aluminum is not recommended for fixtures when welding is present.


http://thegmr.com/wp-content/uploads/2013/02/the-fixtures-for-the-uprights-1024x232.jpg

We start with a Precision machined 1.5 inch thick chunk of steel, then machine the correct holes and tap the plate to provide the appropriate support for the fixture top plate. In the second picture above you can see the actual upright fixture bolted to the main block; this provides a very stable and accurate fixture that will not cause issues because it is not machined from aluminum.

[JasonElvisHeard]

One unique item that The GMR has done is that we matched the stock lower ball joint taper perfectly. We will not disclose the exact taper but we can assure it is not either of the standard 7 or 10 degree tapers. With this being a unique taper we decided to custom machine a reamer that matches the stock taper perfectly to ensure quality fitment with the stock GMR components.


http://thegmr.com/wp-content/uploads/2013/02/upright-custom-reamer-for-CNC-machine-300x268.jpg

The GMR offers these uprights in two different styles, A stock height unit and a 1 inch drop unit as seen below. The image to the bottom left is a 1″ drop upright with a stock height one to the right. These uprights are designed around the stock caliper mounts and ball joints so they will bolt up to ANY C5/6 brake package along with any arms designed abound the stock uprights. These units are also available with a welded on steering arm for direct stock replacement, both in the 1 inch drop and stock height.

http://thegmr.com/wp-content/uploads/2013/02/1-inch-drop-upright-both-of-them.jpg

The new GMR fabricated uprights are only slightly heavier than the aluminum stock components with a weight of only 6.9 pounds each compared to the stock 5.8 pounds. The Stiffness to weight ratio of the GMR uprights are drastically better than the stock units at operating temperature (non-ambient temperature).

http://thegmr.com/wp-content/uploads/2013/02/weights-for-the-uprights.jpg

The GMR Uprights are designed to be universal, from stock replacement hubs to GMR front hubs these uprights will work with any C5/6 package.

[214Chevy]

Looks damn good! :thumbsup: Thanks for the tech info. What about steering arm options?

[itsals1]

Any possibility that these or future styles would work with RideTech's Tru-Turn?

You would retain your current steering arm, it would bolt on in the same manor as it currently does on your OEM's Upright.

So basically if you currently have a Scott Mock, DSE, Roadster Shop, Art Morrison, etc. you would simply re-use the one that came with your particular suspension.

Now, IF you happen to have a suspension that utilizes the OEM's Upright WITHOUT the steering arm machined off, then we DO offer a weld on arm to maintain stock C5/6 location.

Thanks, Jay

Travis

Travis, At this time we have no plans to produce a fabricated AFX version, but its not to say it will not be on the list of "things to do". We are aware of the need as we have had others request the same do to spindle flex and deflection of the upright section itself.

You may want to look into CPP's Upright offerings. They have a Tall A,F,X 2" drop upright that may work with the TruTurn? It would most certainly solve the deflection issue at a very reasonable price.

Hope this helps.

Thanks, Jay

[garickman]

Nice work on the uprights. Looks to be top notch to match the rest of your parts.

Thanks Greg!

Just FYI.... these suckers go great with our Floater Rearends :poke: Oh and dont forget the GMR C5/6 Front Hubs :G-Dub:

[wiedemab]

Just curious on what you would recommend from a coating perspective. I would assume that any mounting surfaces would need to be masked off as to not change the dimension, so any concerns about corrosion in those areas?

Just curious.........

These things look AMAZING

[dontlifttoshift]

I plan on powdercoating mine and we can mask off where the hub bolts up. Actually a good powdercoater can "dust it off" before he cooks it. After that your favorite penetrating oil on the bare surface and assemble. I prefer Gibbs.

Thanks Donny - - - - Just wondering is all.

I may be chatting with you about some GMR stuff at some point - -- - Lord knows my dreams are much larger than my budget though!

[dontlifttoshift]

Cool, my wife gave me an unlimited budget and I still went over:lol:

[coolwelder62]

Jason,These are Amazing.I want a set.But need to buy the kid's G.I.Joe w/the Kungfu grip first.:thumbsup:

[Bryce]

Jason,

Can you share what chromoly you are using? If so can you explain the welding process. What filler rod? Any preheat or post weld heat treating?

thanks in advance,
Bryce

[JasonElvisHeard]

Jason,

Bryce

Its standard issue 4130 plate work. The welding is a multi pass weave weld with an initial root pass then a second pass with rod. I don’t want to disclose the filler but I can tell you its NOT ER70s series rod. I do not preheat or post heat, it is not needed. In reality if you were to do anything more then what I did you will only be wasting time, these are well more than strong enough. Weight is the only concern I have but I would not feel comfortable with decreasing weight anymore because I think it could compromise the strength. I’m happy with the weight they are at now.

I can treat these, but then they will have to be post machined after the treating to ensure quality.

I can even make them from Titanium if someone is willing to fork out the funds for that, but I don’t see it happening often.

Okay...okay Jason. Give us a price now, why don't you? :G-Dub:

[Sandbagger]

What Bearings are being used ? I dont hear about the C5-6 guys complaining about bearing life .
But the C4 guys have few options for a decent wheel bearing . I trashed a set of Autozone front bearings in ten laps at Autobahn last year on Kumho 710s .
Not to threadjack your post ...
Ive been looking for a fix which led me to this topic .
With all the folks using C4 components for Hot Rods ,kit cars and tracked C4s ,there may be a good market for a spindle with a bearing that can take the abuse .
Wish I had the ability ....


Anymore nascar pics btw ?

Just trying to learn a little tech here... What makes the "AFX" so different than these uprights?

Anyone have a spare copy of Uprights for Dummies?... :sieg:


Jeff-

[dontlifttoshift]

Jeff, the GMR upright is a direct replacement for a C6 upright on a stock corvette or on the multitiude of aftermarket subframes and chassis that use the factory C6 upright. DSE, RS, or Morrison come to mind.

The AFX spindle is designed to fit a an A,F,orX body directly and then allows you to use C5 or 6 brakes on those cars.

To be completely apples to apples I believe you would need to add steering arm to the fabricated one right?

[dontlifttoshift]

Depends on how you look at it. For our purposes we should cut stock steering arm off the stock upright.

[JasonElvisHeard]

yeah but I was not going to cut off the steering arm of the stock upright, I wanted to keep her stock for research reasons.

If you want to be fair, then reduce the stock unit by a quarter pound, more then reasonable for the steering arm difference. The reason for the weight comparison was to show that the fabricated unit are not much heavier, or possibly more then double the weight like some would assume.

I think even though its not technically exactly the same the picture still gets the job done with what I was concerned about.

Nice!

Not to take anything away from The Brake Mans stellar and affordable products.........

Your uprights would look mighty fine sporting these too.

just finished all the design for those about 2 months back, the new front hubs for them along with rear rotor adapters are already at machine....

one step ahead of you! :D

Jason

[JasonElvisHeard]

and for the record.... I would still go with brake man over the above for performance reasons....

for "cool" factor I can see why guys love the ceramics... but I will still go with brake man... and use the extra money to spend on other parts of the car along with the decreased stopping distance... :D


now the pot has officially been finagled.....

Agreed, dollar for dollar The Brake Man gets it done.

The Brembo's are very niche oriented, but they definitely rank high in the brake porn category IMO.

Keep up the great product development work.

PS - You're a lot more than one step ahead of me. :thumbsup:

[JasonElvisHeard]

And for everyone,


We have set introductory pricing for the uprights.

please let me know if you have any questions.

thanks
Jason

[214Chevy]

.....
please let me know if you have any questions.



Yeah, um, lets see....you might need to give away a free pair to get the word out on how well these work. Therefore, pm me for my shipping address. :poke:

[wiedemab]

You are right, most of the time the steering arm is cut off for our applications, but I was just pointing out that the stock upright has a steering arm and the GMR doesn't, therefore making the weight difference seem less that it would be in reality -- not all that big of a deal.

Sorry for the de-railing.... Very cool product for sure.
