034 Motorsport has been on a roll recently with developing and launching new products for the B5/B6/B7 Audi A4/S4/RS4 platform that are low cost and high impact, such as the rear diff carrier mount inserts, and these front sway bar end links are another product that didn’t disappoint. Given (almost all) Audis are prone to understeer, and the front-heavy V8 S4 in particular, most S4 owners opt to upgrade the rear sway bar (such as the 034 25mm rear sway bar) but leave the front sway bar untouched to help counteract some of the understeer bias. 034 has come up with a great solution for that with these front sway bar end links that firm up the OEM sway bar without going overboard and making it too stiff up front.
Installation was quite easy, requiring about 15-20 minutes per side, following the instructions on the 034 website. You’ll need a 15mm open ended or box wrench which isn’t a super common size – most tool “kits” skip from 14 to 16mm, so I had to buy one on Amazon before I could get started, such as this one: TEKTON 21321 15mm Combination Wrench. Otherwise, installation is quite simple, and there is lots of wiggle room to maneuver so it’s fairly hassle free. I’m far from a skilled mechanic but was able to complete installation in my car port in under an hour, which says something.
Driving around the front sway bar end links are a great compromise for the daily driver + occasional track rat such as myself – in daily driving these don’t impact ride quality whatsoever and are perfectly suitable for the street, but in hard cornering you can feel the front is slightly firmer and more planted, a welcomed change from stock. I’ve done so many suspension mods that it’s sometimes difficult to discern the exact impact of each change, but I can definitely feel a small yet noticeable impact in terms of hard cornering and steering inputs. Having just got back from a recent track day, the car felt amazingly well balanced between this, my 034 Motorsport Rear Sway Bar, STaSIS/Ohlins suspension, and all of the other mods on the car – very little understeer (and sometimes minor oversteer!), very little body roll, and an incredibly predictable steering response at every turn.
For $195 this is another great mod, I’d recommend doing it at the same time as the rear sway bar and knock these out all at once!
