I bought these to go with the rear sway bar on my TT. They perform great and were easy to install, however these are NOT treated or galvanized to resist rust. I've only had my set through a single New England winter, and the bolts are completely rusted orange, and the spherical joint has a lot of white oxidation as well. I cannot recommend these to anyone that lives in a salt belt sate. I am sad to say this because I love 034's products.
The end link look good and solid, but I gave them only four starts because there was no install instructions. I know the install should be straight forward, but there is no guide to tell which side goes up or down.
As always, great material and quality of this product. The billet pieces look great and will withstand stresses more than OEM endlinks.
I paired these up with the 034motorsports Solid Sway Bar and ran into one issue where the provided allen bolts with the endlinks were not long enough to fit through the endline and the beefier sway bar. I had to reuse the hex bolts provided originally with the sway bar.
Very good quality, however the logic of installing the links with the adjustable end UP is silly. I installed the adjustable end DOWN which allows you to line up both sway bar holes for zero preload. I have built multiple race cars etc. not sure why you would do it this way.
As far as build quality of these end links are concerned they are a very nice piece. I have not doubt that they will last through many years of use on my DD A3 VR6 Quattro.
The only thing I can think of is a small set of install instructions as to the fitment of these end links. They are quite a bit different from stock so knowing which side goes "up" and which spacers go where is difficult at first and takes some trial and error before the fitment is sound.
Other than that I would highly recommend these to anyone needing a set of rear adj. end links.
