Integrated Monoball 2 Point Strut Brace - If you're looking to free up some space in your front trunk without breaking the bank, this 2-point strut brace is a solid choice. Designed to work seamlessly with Rennline's front monoballs, it’s a smart upgrade that doesn’t require any drilling. That means you can install it without worrying about messing up your alignment settings. Made from aircraft-quality aluminum and featuring TIG-welded stainless steel brackets, this brace is lightweight at just 1.4 pounds. It’s all about getting that performance boost while keeping things practical.
Integrated Monoball 3 Point Strut Brace - Now, if you're serious about your handling, the 3-point strut brace is where it’s at. Rennline has crafted this piece specifically to integrate with their front monoballs, creating a front suspension system that you just won’t find anywhere else. This brace bolts directly to the tops of the monoballs, locking in some serious rigidity. That means when you hit those hard corners or slam on the brakes, you’ll notice a dramatic reduction in camber changes. Unlike other options that just anchor to flimsy trunk sheet metal, this one connects to the brake booster mounting studs—one of the strongest spots on a 911. For those with power brakes, it’s a true bolt-in system, and again, no drilling is needed. Plus, you won’t have to worry about changing your alignment settings. Both the upper and lower bars are fully adjustable, so you can dial in the pre-load just how you like it. Weighing in at only 2.6 pounds, it’s a lightweight upgrade that packs a punch.
