Spherical Rear Trailing Arm Kit, MkV/MkVI Volkswagen Golf/Jetta/GTI/R & 8J/8P Audi A3/S3/RS3/TT/TTS/TTRS
We Also Recommend
The 034Motorsport Rear Trailing Arm Spherical Bearing Upgrade Kit is designed to replace the factory rubber bushings, resulting in improved handling, and more predictable and precise cornering.
Factory rubber rear trailing arm bushings deflect under load, causing the rear end to feel vague and loose, as well as leading to improper suspension geometry and increased understeer. This becomes especially apparent when cornering on uneven surfaces, where the back of the car can feel floaty or unpredictable. The same exact rubber bushing was used by Audi/Volkswagen on a variety of applications, from the Volkswagen Golf to the Audi RS3, leaving much to be desired by enthusiasts and competitive drivers alike.
This kit replaces the rubber bushings with motorsport-quality Aurora Spherical Bearings, which allow for proper articulation without any deflection, ensuring precise handling, and confidence-inspiring road feel. Unlike polyurethane bushings, spherical bearings allow for full suspension articulation without binding, while completely eliminating slop from bushing flex.
Please Note: We recommend getting an alignment to factory specifications after installing the 034Motorsport Rear Trailing Arm Spherical Bearing Upgrade Kit.
"Bought it when on sale. Had installed this week prior to a track day on Saturday. The car was re-aligned on a Hunter post install.
Car felt clearly better in handeling and rear stability.. Thumbs up to 034. worthwhile if you intend to track for sure.
No (added) noise. the guys at Texas Track Works who performed the work are very familiar with this style of upgrade for many track car applications. They anticipated I would see a marked improvement. This is one of those fo sho things, not subjective or power of suggestion things.
No other bushing upgrades, but as I drove back from Fort Worth this morning, I was thinking about reserching any and all other type/similar upgrades. Factory rubber bushings are just not made to really take the loads from true "driving".
I think I remember that 034 would release more items along this line. I'd be receptive!"

I installed this on my MK6 GLI along with some end links and a 034 RSB, and I also have to say that the rear feels better connected and the car has become more predictable. Since the GLI has some extra weight in the back over the GTI, these really helped control the "squatting" under acceleration and improved grip. The car no longer feels like it is jerking back, but staying more level during acceleration. I also have yet to experience any additional NVH, and with over 1000 miles on them I don't think any will show up now.
The only real downside is that these are pretty pricey, but I think they are well worth it for tuned cars who are looking for another solution to help put the extra power to the ground.
Had this installed with new the 034 endlinks and i have to say the improvement over stock is noticeable. I can't say it reduced or help understeer or oversteer, but the rear wheels have much better control. The tires feel planted and a bit more accurate over bumps and uneven roads. Along with the sway bar, the car doesn't feel unsettled like it did at highspeed over bumps or wavy roads. Much of the feeling as if the car was shaking is reduced and the car now feels like it is always moving straight forwards on the right line.
For the price...I can't say if it is worth it for average drivers though. I didn't buy all these at full price thanks to discounts, but i don't think all of the upgrades would be worth it full price. The steering feel and front end feels much the same which is the biggest issue for our cars.
Because of that, this type of upgrade is not that important.
