If you own a BMW E9X, you know that the factory front control arms are crucial for a smooth ride. But let's be real—if you’ve been pushing your car to its limits, you might start noticing some wear and tear around the 40,000-mile mark. Those rubber bushings can degrade, and the ball joints can get a bit wobbly, which messes with your alignment and makes steering feel a bit off. Trust me, it’s not a fun experience when your ride starts feeling loose.
That’s where 034Motorsport's Density Line Control Arm Kit steps in. This isn’t just a replacement; it’s a serious upgrade for all eight of the factory front upper and lower control arms. With high-durometer rubber bushings—65 durometer, to be exact—this kit is built to handle the demands of spirited driving. The ball joints and Heim joints are top-notch, designed to minimize unwanted deflection in the suspension. What does that mean for you? Tighter handling and a more direct steering feel that even brand new factory parts can’t match.
One of the standout features of this kit is the M3 style design, which gives you an extra -0.75° of negative camber compared to the non-M arms. This little tweak can make a noticeable difference in how your car feels on the road or track. You’ll find the handling is sharper, and the steering is more precise—just what you want when you’re pushing your BMW to its limits.
What’s in the box? You’ll get everything you need: front lower control arms, a headlight sensor rod, and all the installation hardware. It’s a complete drop-in solution, so you won’t be hunting for extra parts.
Here’s a quick rundown of fitment:
And just to be thorough, this kit fits a range of models, including the 316d, 316i, 318Ci, 320d, 330i, and beyond. If you’ve got a BMW from this era, there’s a good chance this kit is what you need to keep your suspension in top shape.
So, if your BMW is starting to feel a bit loose, or if you’re just looking to enhance your driving experience, give this control arm kit a shot. You won’t regret it.
