Racer X Fabrication suspension parts, and development
 

Well for a little back ground check out our intro thread here:
http://www.ft86club.com/forums/showthread.php?t=30916

We picked up our BRZ last September and have been busy developing parts and now we are finally releasing them. The rear lower control arms are full 4130 chromoly steel, along with the trailing arms. We make all of our own parts including the threaded rod ends. This allows us to be quite creative at times, and in some cases build several prototypes until we are happy with the result.

Here are the rear control arms, trailing arms and adjustable rear end links. We are currently finishing the front control arms and will release two version one with the OEM ball joint and the other with a fully adjustable spherical bearing at the ball joint location to optimize handling for racing.

Front lower adjustable control arms added: 3/20/13 (pics below)

Rear upper adjustable control arms added: 3/26/13 (pics below)

Final pics added: 6/2/13, starting at post 95

If you have any questions about parts we are working on, our would like us to develop some parts you might be interested in feel free to shoot me an email : info@racerxfabrication.com

Front control arms development, and OEM front adjustable end links
 

Here are a few pics of the development we are working on for the front control arms. We have 2 prototypes, and currently working on a 3rd. We should be releasing these soon.

(Update): Front control arm design is finalized, and we will be running a pre-order for them soon. Pics added below.

We also have OEM front adjustable end links for the sway bar.

Whose bearings and which specific models are you guys using? Everything made in the US?

^^I second this^^

Looks good though!


nevermind i found it -Built in the USA, at Racer X Fabrication for complete quality control

What are people's opinions about running rose joints on the street? I'm worried about dirt and grime screwing the ball joints but don't know if its validated or not.

RacerX. Nice to see you here. Another MR2 guy.

We use FK rod ends, PTFE lined 3/4-16" thread diameter. We can use any bearing you would like if we make a set to order, we are pretty flexible about these things.

Yes, we build just about everything in house. The only exception on these parts are the rod ends, and ball joints.


We can provide the rod ends with dust boots. We have been using the rod ends on the street for sometime in the MR2 application with no ill effects. They are great in racing applications. We have been considering offer the arms with a urethane bushing.


Glad to be here!! Nice to know there are a few other MR2 guys on this board as well.

Looks good! How will you be pricing these control arms?

Whew. Thought you were that racer x guy from LGT. His stuff is Chinese knockoff stuff.

Looking good!

I hope the pricing on these front LCA's is decent because I really want to get rid of the squishy front suspension components, but I'm too lazy to replace all the individual bushings with poly... These with some good top hats, and I'm good to go out front. :thumbup:

Which series FK? Did you use those because most don't want to pay or NHBB or even Aurora bits or just prefer the FK ones? No I'm not saying FK is bad :)

We will be running a group buy/sale thread in the vendor section soon. Right now pricing is available on the website, you can click the logo in my signature if you would like to check prices.

Yes, we are proudly made in the USA and the majority if not all of the product is made by us. !! We have received emails before about Racer X Engineering products.

We will do our best to keep price reasonable, that is one of the benefits of making the parts it gives us much more control over price.

We will use the FK-JMX12T. You have actually brought up a good point, we should offer the other rod ends as a choice. I will have that added as an option drop down on the site. You are correct, most do not want the added cost of a very high quality rod ends or bearings. From our experience the FK rod ends/bearings are quite stout and a good price for the quality.

FK JM is good stuff. :thumbup:

If I need some camber adjustment after my coilovers finally arrive (they need to be built still first...) I'll definity take a look at those LCAs although I still like adjustable UCA instead :)

We are building the jig for the upper control arms now, we should have something soon.

Any features you would like to see?

in for upper rears!

A bushing option for those that want camber adjustment that doesn't mess with the track width too much and don't want bearings on their DD. :thumbup:

This thread, I like it! Personally, I DD my car and would prefer corrected geometry without the use of bearings.

Just camber adjustment through the UCAs really is all I'd care about.. with bearings.. and bushings for the people who care above I guess :)

Hmm, my first post went missing. Maybe I never hit submit.

Any chance of making the arms adjustable on the car? Your end links can be adjusted without removing one end, yet, that is the one piece that doesn't really need that.

If I am doing some tuning at the track/autocross it isn't very easy to undo one bolt of a control arm or toe link and adjust it then put it back together. It really needs a RH and LH thread so it can be done on the car.

Looks like quality stuff. A privately owned business, manufacturing in America? You get my vote any day.

BEARINGS, low unsprung weight and adjustability!

increases NVH but well worth it! (and anyone with an exhaust wont notice a differance in sound level.).

I will take a look into the bushing design, it should not be hard to offer this for the guys that do want to DD their car and hit the track.

We have considered this, and will be offering it for the lower control arms and possibly the fronts depending on final design. I will update with the new option when we have the components ready.

Thanks!!

There is a weight savings to be had with the upper control arms. The rest of the components we have made we saw the weight equal to the OEM or slightly less (a few ounces)

Here are the front suspension studs we make for the lower control arm spherical bearing. A few in process at the moment.

The rear jig is tacked and once we check the prototype it will be finished.

We should have some updates for the front control arms, and upper rears this weekend.

I would have suggested these, but I wasn't sure on the availability.

Front control arms
 

Well we finished the front adjustable control arms this weekend. We made a few finally changes for the front arms which are:

-offset bushings for the primary arm
-bend to provide more steering angle clearance
-spacer set for up to 2" of RCA movement

We are sending the arms out for powder coating now, they are full 4130 chromoly, and the tapered rods are getting zinc plated. The full arm with hardware weighs about 5 ounces more than the OEM arm.

We are currently working on the rear upper arms and I am pretty excited about them.

Those look really nice. Good work guys.

Interested in adjustable rear UCA's as well.

Awesome work!!! I've seen your handy work on the mr2 forums can't wait to see what else you have on the way:bow:

Control arms look great! Can't wait to see the UCAs! Pre-order special or group buy? :)

Thanks guys!!

We will be running a group buy for all of the suspension components in the next week or two.

An important question to ask is, the way you've designed the offset bushing on the front arm to line it up with the outer ball joint, will this increase or decrease caster? Just looking at the pics alone, it looks like it decreases caster because the ball joint will move the knuckle further toward the rear of the car. Of course I could just be dyslexic.

The offset bushing is used to reduce the rod end misalignment. The arms hold OEM position until the rod ends are adjusted.

Adjustable toe links, part installation and weights
 

We finished the toe links a couple weeks ago with the adjustable rear control arms, adjustable trailing arms, and rear end links. We made a small change to the tapered rod, and did not want to post them up till we had the updated design completed.

12L14 cold rolled steel hex stock with 5/8 LH/RH rod ends, tapered studs provide a perfect fit to the hub and we use hex stock again to eliminate extra fastners. We will ship out the tapered studs to be zinc plated. These Will provide strength and durability for all customers looking to have great handling from racing to street. We will provide custom tapered rods for those guys that want the capability of bump steer adjustment. Be aware that it will impinge on the e-brake cable. Currently there is roughly a 1/2" of height adjustment this would not be enough to properly provide the range required.

We should have the rear upper arms completed this weekend and will update again then.
