If you're serious about getting that sweet handling performance out of your Porsche 996, 997, 986, 987, 981, or 991, you really need to check out the Rennline GT3 OEM-style control arms. These aren't just any control arms; they’re a solid upgrade over the factory single-piece arms. Trust me, once you make the switch, you'll feel the difference in how your car handles, especially if you're hitting the track or just want to enjoy some spirited driving on the back roads.

What I love about these control arms is how easy they make adjusting your camber. Whether you’re looking to dial in more negative camber for the track or just want to tweak it to match your driving style, it's a breeze. The construction is top-notch, too. They’re made from forged 6082-T6 cast aluminum, which means they're not just lightweight but also way stronger than the stock GT3 arms thanks to the forging process. You can really feel that added strength when you're pushing your car to its limits.

Another cool feature is the Zerk fitting on the ball joints. They come pre-greased, and you can easily re-grease them down the line, which is a huge plus for maintenance. Plus, the inner control arm bushings are made from 6061-T6 aluminum, and the thrust arm bushings have a 75A durometer rating, so you know they’re built to last while still giving you that responsive feel.

Now, if you’re looking to really maximize your setup, you'll appreciate the additional negative camber you can achieve with shims. Keep in mind, if you're working on a 997, 987, or 991, you’ll need thrust arm spacers to make everything fit just right. Also, a heads-up: these control arms aren’t compatible with the 991 GT3 or 981/718 GT4 models due to their different designs.

Here’s a quick rundown of the torque values you’ll need when installing these bad boys:

• Bushing to control arm: 27Nm (20 lbs.-ft)
• Inner control arm bushing to body: 120Nm (89 lbs.-ft)
• Thrust arm to control arm: 160Nm (118 lbs.-ft)
• Outer ball joint: 75Nm (56 lbs.-ft)

And just to be clear on fitment, these control arms fit a wide range of models, including:

• Porsche 718 Boxster (2017-2024)
• Porsche 981 Boxster (2013-2016)
• Porsche 986 Boxster (1997-2004)
