Suspension Dirt cheap swaybar endlinks
#1
Color me stingy, but I couldn't see spending $109+ for a pair of swaybar endlinks, especially after forking over the $119 for a set of Perrin links for my Evo... shoulda known better, but I learned. Note that the stock endlinks are 9.25" long (23.5 cm). If you lower your car you should shorten the endlinks to maintain the swaybar at a position parallel to the ground when the car is on a flat surface. With a set of H&R springs I find 8.5" is the correct length for the rears.
So here is how you make your own for less than $40 a pair, and I even did 2 versions for personal testing:
All parts except misc nuts/washers are purchased from McMaster-Carr, and you can do a direct search on the part numbers to add to your shopping cart. All fittings are 3/8" by 24 thread, so close to the stock 10mm that its not worth paying half again as much.
First set, traditional hollow tube middle with male end links. Require 4 each pn 60645K241 zinc plated male right hand thread end link @ $5.85 each - $23.40 so far. Then add 2 each 6516K61 RH threaded 6" connecting rod @ $6.57 each - $13.14. Then get some 3/8" by 24 thread nuts and washers from your local hardware store, roughly $2 for 8 nuts and 4 washers. Total damage $38.54. Only issue with these is that the max length should be 8-1/2", otherwise there doesn't appear to be enough thread engaged into the connecting rod. So use this setup only on a lowered car:
Next one, the one I use on my car, more of an industrial T3 look: 4 each pn 6072K33 female RH threaded self lubricating rod ends @ $6.27 ea - $25.08. Then add one pn 98848A031 stainless 3/8" by 24 thread 3' threaded rod @ $5.44. I splurged on 4 stainless jam nuts at Ace Hardware at $.35 each, plus $1 worth of regular 3/8" nuts and lock washers. Total damage $32.92. This one can be made to any length, so I will use this design to replace my front links soon as well.
Comparison of the three end links:
And one shot of the tube style in the car:

Maintaining the swaybar parallel to the ground gives optimal handling. When you lower the car the link end tends to rise up at an angle as the wheel sits further up into the wheel well. So shorter endlinks are a good thing. Another issue is people breaking the stock links, mostly when they are using a performance swaybar and doing some hard driving such as autocross (my main reason for owning the car, other than the chick-magnet factor). So there are several good reasons for going to a stronger, adjustable endlink. No cons that I have seen so far.

Rear control arms would more of a problem, mainly due to the spacers required for each side of the heim joint to fit into the frame and spindle mounts. They need to be a good fit so the end joint would not slide side to side on the bolt. I have a set of RDR control arms on the way now, and will see if I can find any off the shelf parts that would work as well.
I have found a few online suspension stores that sell large internally threaded connecting rods, for use on control arms/panhard bars, so that piece wouldn't be an issue, only how it would bolt up securely.
As for noise, not so far no. Same amount of road noise from the Azenis as before, and no noticeable clunks/rattles.

Thanks for posting this info, I have been planning to get adj. links for some time. I am still somewhat concerned about failure though as a very smart friend made links for his MINI and broke or bent one during one of the first autocrosses he had them on, at the Virginia Pro-Solo, last year. He said something later about needing more offset on one or both ends. Do you foresee any problem in that regard? My MINI ran about 20 autocrosses last year sometimes with two drivers always lowered and on some less than perfect pavement, like the North course at the Solo Nationals and never bent a stock link but I would like the ability adjust their length for several reasons.
Are the hollow links noticeably lighter?

Excellant how to, very well done. YES it is necesary to use the correct length end links. We found this out the hard way two weeks ago when a lowered Mini had the end link fail . It wa apparent that at a angle the already suspect piece just couldn't do the job. It is designed to work level with the bar and when it isnt it is at a very weak angle. The end piece just pulled out causing a minor wreck on a canyon run. Total loss was two Volk racing wheels , one drive shaft and a nice afternoon. Could have been worse.If you drive a lowered Mini aggressivly you should really think about swapping them out. Make some like these or buy some from a vendor but at the very least check yours frequently. Randy

Do you have any plans for DIY rear controll arms.
>>I'm tight myself and would rather fabricate/build what I can rather than throw money at it anybody can do that. It's a hands-on hobby for me.
Cool thread (no pun intended). Althought they design for high misalignment, check out this site for link fab.

I ordered set of endlinks from Randy but he told me the failure(a?) he was experienced with occurred with another make of rear bar than the Alta which I have. The bar which had the associated failure was not bent right and I there was some interference between the endlink and the spring. He didn't think there would be a problem with the Alta and stock springs. He talked me out of the purchase.
Thanks for the How-to. I love reading this even if I (hope) I won't need to do it. However there is a slight clunk in the front and I am thinking maybe an endlink is bad, should check.

the links are exposed to some nasty road funk and weather and the 2Cool specified rod ends are un-protected. Note that the stockers at least have one side sealed and a rubber boot aroung the stud to protect the spherical joint.
I recall seeing rod end boots out there somewhere; deifinitely worth having.

Every aftermarket endlink I have seen, from Alta to Perrin, uses open rod ends. I used the Perrin ones for 9K miles, with no issues. I did spec the stainless threaded rod and jam nuts, as well as the self lubricating rod ends for my MYOS (Make Your Own Sh*t)endlinks. Those items are above the quality levels of the $119 Alta parts.

ditto 2Cool's observations - the stock rubber-booted endlinks only see a very little bit of turbulence-applied dust. The positioning on the car does not put them in harms way in terms of moisture or debris/dirt. I would say the stock unit's using boots is counteracting the ultra-cheap spherical bearings underneath from losing their lubrication.

in any dirty environment, i'm with jlm. i like greaseable spherical joints with boots. some sources:
