UMI Performance

You guys spoke and we listened. We have redesigned our lower A-Arms and added the things you would like to see to them including bump stops, spring index and steering stops. The steering stops are adjustable to work with a variety of wheel and tire widths.

Those very well may be the best pair of aftermarket A-Arms I've seen.

Primetime91

iTrader: (15)

Those look very well made.

UMI, if you want to improve them further, how about an "upgrade" option which replaces the poly bushings with a bearing?

//<86TA>\\

iTrader: (14)

they do Delrin bushings already

bearings wear out a lot faster, and in this application, not a great upgrade over a good bushing IMO

Primetime91

iTrader: (15)

A bearing in this application offers the best of both worlds. Less deflection than a bushing, & they actually ride & operate smoother too. Have your cake, & eat it

itsMikey

yup..

awesome to see that you guys actually listen to your customers!!

How would these work with 2" Racecraft dropped spindles? Would the steering stop at the right place?

P.S. Awesome job UMI.. Glad you listened

UMI Performance

This is correct, we offer a Delrin bushing options which allows the arm to travel up and down with very little friction.

They should work just fine. As long as there stop is in the same place as factory I don't see why not but haven't personally tried it.

Thanks everyone for looking!

always went with UMI nothing but the best just need a K memeber so I guess im building my own

hellz_wings

iTrader: (2)

A tubular K-member would definitely make all the work in swapping to this newer, redesigned a-arm worthwhile!

lunati397

Im going to build one to work with power rack and pinion

hellz_wings

iTrader: (2)

Imagine a bolt in K-member / a-arm combo with a power rack and pinion with a 12:1 steering ratio (like the IROC boxes)? That's something I would buy in a heartbeat! (ofcourse it would have all the braces and stock mounting points so it really is just a "bolt in" setup)

lunati397

thats what im putting together now a bolt in k member a arm setup with power rack same turning radius with 2.25 or 2 turns lock to lock so better than the iroc boxes

Ive found the rack and it will work just has to be ajusted to get the 6 in of throw

hellz_wings

iTrader: (2)

yeah it's lighter weight and the weight sits lower and in the center of the car and it connected to the beefy k-member instead of the crack-prone frame where the steering box mounts to.

AM91Camaro_RS

These look great! my question is...would it not be beneficial to also incorporate some type of "hook" over the top of the tubes from the spring pocket? Thats just a ton of sheer force on the welds holding the spring pocket in place.

lunati397

welds especially good welds are stronger than the metal

Primetime91

iTrader: (15)

Because welding reduces the surrounding metal's strength in the head affected zone... Just saying

Not too significantly with mild steel, but chromoly is a different story. Welding doesn't "Make the steel stronger", it's just stronger in comparison

Since this topic got brought up.... UMI, that's another way you could set yourself above the competition. As far as I know, the only aftermarket company that post-weld heat treats it's chromoly suspension components is J&M. I kinda wish more companies did...
I have no idea how many welds, if any have failed on your chromoly pieces, but it's just an idea.

Do these work with the stock K member or do you have to use the tubular one?

hellz_wings

iTrader: (2)

They work with stock k-member. I have their older model and it fits great.

stereojnky

iTrader: (2)

Thanks. I can't remember who made them, but I remember someone complaining about the a arms without the k-member moving tires tires back. Could have been BMR I don't know. Do you have any pics you could pm me?

KiLLJ0Y

iTrader: (1)

question... what is the over all benefit to using these types of A-arms over stock? i mean the weight savings can only be minimal at best.. 1-2lbs?

hellz_wings

iTrader: (2)

Besides looking fancy, they are probably "stiffer" than stamped steel ones (not sure if the gains from this are ever noticeable). But these comes with poly or Delrin bushings which are an improvement over stock rubber bushings (although you could install poly or delrin in stock control arms). They also come with new balljoints. These comes with adjustable steering stops, bump stops and finally a spring index (yay!). But to be honest, the weight savings are advertised as 5.5lbs of savings and that's not that much but it IS unsprung weight so there are definitely other things you can spend money on FIRST before you get these, although if your car is already fully done over then yes these are "better" than stock. I do like the way they look under the car though, damn sexy lol.

I want a set to put on my desk and admire......

And another set to put on the car.

Is there a part number for a replacement ball joint boot? I bought a set of your arms a while back but one came with a ripped boot. Looks like it got snagged during the ball joint install.

My biggest question is also my biggest concern. How is it possible that UMI did not realize the deficiencies in their original product? This is just my opinion, but I feel it's kind of lame for a company to have to realize the shortfalls of it's product in an online forum. Where is the Research and Development that goes into these products? Are these items not test fitted, scrutinized and reevaluated before the product sees actual production? I have the following products from UMI: 22mm Chromoly Rear Sway Bar, Chromoly Pan Hard Bar Double Adjustable with Rota Joints. Chromoly Double Adjustable Lower Control Arms with Rota Joints, Lower Control Arm Relocation Brackets (bolt in), Steering Brace, Cast and Camber Plates...


just my thoughts

IMHO almost anything you buy first gen is pretty much a "beta" product. Cars, software, electronics, all get better as we figure out what we don't like about the product. It's no secret that companies use consumers to test their products. For the most part I just choose not to be a test subject.
You could maybe argue that it took too long to make the improvements, but I have yet to see a product introduced that doesn't need improvements/updates.

L695speed

Hmmm, perhaps I should spend 411 bucks in the near future......Summit's shipping is cheaper for me. These just look awesome. I'm sold, now to rob the nearest convenience store of a measly 500 bucks to buy'em.

Project 3.4 Camaro

I have to agree, no product hits the market as good as it can be, it was lacking features, not fatally flawed. If they were snapping right and left, and they didn't promptly revise them that's one thing, adding new and improved features is quite another...

88fastgta

iTrader: (9)

i just dont really see any advantage to this other than looking nice and flashy.... you can paint your stockers and put poly bushings in or those expensive derlin bushings in and have a control arms just as good for half the price of those...

the stocker a arms are plenty beefy and imo are beefier than the aftermarket setups.... i just wouldnt trust all the weight on those a arms on weld spots like that on a daily driver hittings bumps and all. and with all the problems poeple had with aftermarket a arms in the past i rather just spend that on something thats more beneficial...

AM91Camaro_RS

I don't know if I'll ever put them on my car if it sees a lot of street use. But, while they may be built to hold up to street abuse...they're not really built for street cars. That's more of a race part, realistically.

UMI Performance

We have never had issues with the spring perch being welded, it is welded fully around the ring and has been this same way since 2006 on all our A-arms.

Umi - will you guys consider a trade-up program? I recently bought a pair of the old style and would like to get the new design.

iTrader: (2)

Hat's off to you guys for listening & improving a product...
Shame on Spohn for selling a part that is clearly wrong defective
(moved my wheels back int he well and rubbed-Addressed them several times, still no response)....

I ended up wasting tons of $$$ with Spohn a Arms, remove stock, install spohn, alignmens, defective part, buy upgraded bushings and ball joints for stock, paid to get that put in, get spohn out and ANOTHER alignment.... $1000 wasted...

Go for the UMI guys...

I know what item im buying next

iTrader: (9)

when's the next UMI 10% off sale so i can buy some stuff?? i was hoping you'd do a Labor Day sale, but no luck.

hellz_wings

iTrader: (2)

They did a labor day sale i think they were offering 15% off.

L695speed

I can confirm that. They had 15% off. I almost pulled the trigger on the arms then. Then realized they would have been flopping in the breeze because of no spindles or strut mounts. (I will use Koni Yellows but I can use the old blown struts for build purposes)

I did however get a set of Tie Rod adjusters and the on car adjustable panhard bar. Both were 15% off.

very nice...where's the k-member?!

UMI said next summer! So, come spring time, i'm hoping to have my mouse click the "add to cart" button for a UMI k-member

stereojnky

iTrader: (2)

NICE!!! Can't wait! Just judging from these A-Arms, it should be well thought out and well constructed.

I'm waiting for the UMI k-member a-arm combo.

PLEASE make it so I can give you my money.
