Adjustable Control Arms, take 2

[Ian]

I'm getting ready to install the first gen arms as well.  Can't wait to try them out this summer!

First of all I'm not trying to stop you or put you down. I'm just offering information and some constructive criticism. I applaud you for making your own parts and offering them to the community.

Thank you and no offense taken at all.

 

pm'd as to not derail this thread with too much transmission stuff. Will start a thread for that product eventually. 

 

Thanks,

WOW dude, I am amazed at how quickly these have been refined and I love all the details and planning you've built into this endeavor. Well done. Incredibly sad I missed out on the first run. This has been one of the most interesting 7 page reads I've been on in the last couple years.

 

I'm frying some really stupid fish with my current car but the second I get it rolling again, I'm coming back to look at these. I may have missed it, but do you have a website or something I can bookmark?

[BGB]

Where can these be purchased? Sorry If i may have missed this

[gracer]

If I were still racing, I would be all over your product.  I had been looking at doing something like that using parts made for stockcars.  G

[mttpekin]

Thank you all!

 

I installed on my car yesterday. Feel free to disregard the cleanliness state of the engine. A fairly comprehensive powertrain revision is being penned and parts built/amassed, so this original motor is not long for this car. Also, I bought an auto trans car for the wider tunnel which is fairly nice when installing significantly larger transmissions. 

 

I timed install and it took me 12 mins per side. I videoed the installation and will soon have an install vid. I'm planning a video of adjusting but that will take a little longer as that means setting up the alignment things in the garage and explaining all of those things..

 

To all inquiring about site and purchasing, I'll PM you regarding status and provide all information. I'm building a site currently and as soon as it is ok I'll be putting the link here.

They look awesome!

 

And more transmission talk- if they fit the m10, they'll fit the s14...

Hmm, based on your install, it looks like a set of beefy (factory location) anti-sway bars will fit fine. That is good news. I didn't want to change much on my car, in that department.

truth. I am going to install a set of thick sways myself in the next couple days.

Random question. 

 

Any weight savings over factory? I would think so, but curious as to how much. 

[mttpekin]

Hi @M3This

 

Here's the definitive answer. I've been curious myself..

 

My product weighs 0.53lb more than the stock each. 

 

stock: 5.51 lb 

not stock: 6.04 lb 

 

If this is not acceptable, I will make you a set out of titanium for a 'modest' price increase. haha

 

Thanks,

Wow I’m surprised the stock set up is actually less weight. 
 

Thanks for sharing. 

[mttpekin]

@M3This Yeah no problem.

 

The factory control arms in my opinion are a pretty & elegant solution. Stamped symmetrical sheet metal spot welded into an I beam and a single forged rod are the easy and inexpensive way to mfg 2million pieces and it works. There are a couple compromises you make w/ that setup though..

 

My product is not as simple in principle but eliminates a lot of the compromises I see w/ the stock arms eg. rigidity, adjustability, and consistency of motion. 

 

I'm pleasantly surprised that I'm within half a lb of the stock arms while allowing provisions for perfect alignment.

 

Best

These look great, @mttpekin - perhaps rules will change and one day they'll be legal in local vintage racing organizations. That said, I've got a resto-mod street car project these belong in.

Here's a data point for a 'thick' front sway bar set-up (it's interesting ... not my design or work). -KB

I ran similar Bar set up in the Autocross car, but mounted the end links to the strut and the body of the bar mounted in the same spot as IE bars.  these are hollow and the wall thickness dictates the strength.
