All around LCAs

[whitestang5]

Guys,

Looking at these three LCA to get some of the wheel hop out of my Boss, would like somethings for autocross and the strip let me know if you guys have any experience with these

Which ones would you choose?

 

[Sam Strano]

None of those unless you want to pay way too much.

Realize that at least under SCCA rules, changing LCA's will keep you from running stock or Street Prepared category, you will be off to SM or Prepared most likely. Bear that in mind.

Here is a link to the list of the LCA's (and some other things associated) that I carry: http://stranoparts.com/searchbymodel.php?CategoryID=201&ModelID=35

To compare to your option 1, I'd recommend the UMI 1035 or Steeda 555-4422.

To compare to your option 2, I'd recommend the UMI 1037

To compare to your option 3, I'd recommend Steeda 555-4405.

Now, I'd recommend none of those if I were asked. I would point you to http://stranoparts.com/partdetails.php?PartID=535&CategoryID=201&ModelID=35 or http://stranoparts.com/partdetails.php?PartID=721&CategoryID=201&ModelID=35

Both of those give you a joint at the rear that allows full and free axle articulation (urethane at each end will not give this they actually bind up the axle movement), while getting the noise isolation of the urethane bushing in front. The Steeda's use a really high end spherical bearing. The UMI roto-joint works the same way while being rebuildable too.

Sam,

Thanks for the info I thought that the hotchkis had a spherical bushing on one end?
Not to sure on how tight our autocross rules are around hear got to find out on the lca change but looking to just have some fun

 

[Roadracer350]

Why not run rod ends on both ends?

These UPR control arms are a good combination of free articulation without excessive NVH. Plus, they're Made in America, they carry a Lifetime Guarantee, and they're inexpensive.

Whiteline. The bushings are made from a proprietary material that acts like rubber at low speeds (to keep a compliant ride) and polyurethane at higher speeds. The special grease they supply also eliminates all noise.

I highly recommend an LCA that features a synthetic material bushing up front on the chassis side, and a spherical style on the axle side, if all-around performance, specifically handling, is your goal. This will also alleviate NVH better than a design that has the spherical end on the chassis side (UPR linked an arm that has spherical on axle side, not sure why anyone would want that)

We have a few options that feature decent price tags, and will provide the user with the highest quality parts and the best service on the market. Check out our LCA section!

The TCA021 is a favorite for most corner carvers. We have many, MANY happy customers running those.

Let me know if you have any particular questions about any of our products.

Happy Modding!

If they've discovered material that morphs I'd think they'd be doing better things with it than making bushings.

Everyone makes a claim about this or that, but the fact is having "trick bushings" isn't anything new. There are these 3 piece ones that are supposed to work like a rod-end that have been around for years, but they really don't because the ball and the outer cups are both urethane. The cups are soft urethane, but still urethane and urethane on urethane sticks.

I sell Whiteline products, or rather I can (and I do sell a good bit of it for the FR-S/BRZ), but I don't buy the claim they bushings are magical. What you want is rotation without fore/aft or up/down movement. A joint that allows free rotation in both directions is the one that gets the least in the way handling wise. At that point the front bushing isn't a problem because the axle is free to rotate independently from the body as it rolls.

No I didn't. I posted arms with the spherical on the correct side.

Who says we aren't? I think you'd be surprised what types of things we make...

Right, and what you are talking about there is an issue with innovative design failing due to limitations with the materials; limitations we don't have with our products.

At that point the front bushing isn't a problem because the axle is free to rotate independently from the body as it rolls.

I don't think anyone has ever claimed they are magical, but if you want me to add some sparkles into a special batch for you I can. Bottom line is our product isn't new, it has been around and been proven for decades and it only takes a minor amount of research to see that. Have our bushings always been this good? Nope, but we have innovated to this point, learned from our experience and got where we are today because of it. Keep in mind, Whiteline's bushing heritage actually comes to us from our sister company Nolathane.

The product may not be for everyone, some people just like to keep with the old "use what works" approach, but in an industry of innovation those without new ideas will be left behind. Ask anyone here who has given Whiteline a chance and you will hear overwhelming positive responses from shops, racers and general enthusiasts alike.

Thanks for your continued support Sam! We all respect your opinion!

Kelly, I've got suspension parts from BMR and UPR, and I'm more than satisfied with both, but posts like this, which I've noticed are increasing lately, turn me off to your product. I'm just offering this from a business standpoint. I haven't noticed it from Sharad, but I would feel the same way about UPR if it was coming from him.

/Sorry for thread jack.

 

[BMR Tech]

No I didn't. I posted arms with the spherical on the correct side.

I was not aware that you guys made a product change. If that is the case, I owe you a beer @ PRI. That is only contingent upon you posting an updated picture of said arms.

While I do apologize, I was speaking how I feel about a poly/rod-end combination LCA. I would never recommend anyone run a Poly on the axle side, with a spherical bearing on the chassis side, as it just does not make any sense. I will assume that the design was recently changed, fair enough.

I can only assume the design has changed, because the picture on the link clearly shows an offset built into the Poly side of the arm, which goes on the axle....AND this post made on this very Forum:

^^I'm with this guy. (although our arm is spherical on the body side and poly on the axle side)

http://www.uprproducts.com/mustang-chrome-moly-single-adjustable-lower-control-arms-street-05.html

Carry on.

 

[Diabolical!]

You guys both do a great job on this forum as far as I'm concerned. I appreciate the parts I run and input I get from both of you guys. I may have taken the post wrong. Might not have been my place to speak up.

What is the patent number on this new bushing material?

Nothing against Sky Render, but the web site he writes for has a well-known relationship with Whiteline, so I take his posts with a grain of salt.

 

[whitestang5]

Guys,

Thanks for all the info went with the hotchkis, hopefully made a good choice

 

[sheizasosay]

I take it J&M is not a vendor here. I have had double heim jointed LCA's (still have them), J&M polyball, which if I am not mistaken, is what Sam is talking about with the urethane cups, and I now have the J&M Street Extreme versions. The street extremes are flippin' nice. I don't even see how the polyballs sell considering the street extremes are superior and I couldn't tell ANY difference in NVH increase over the polyballs. They are awesome. I have never had the experience of a rotojoint, but it sounds somewhat simliar atleast in characteristics of the Street Extreme joint. I would probably say the roto jointed LCA and J&M Street Extreme would be after the exact same market if I read it right: an LCA that works fantastic on a road course that you can live with on the street, that has significantly less NVH over the ultimate race joint...the heim. I wouldn't mind riding in a car with roto's to see for myself. 3 different LCA's are enough for me though. I'm satisfied where I'm at with the LCA's.

I have whiteline along with their Relo brackets and am extremely impressed with the performance and comfort it provides.
