If you’re a BMW 3 Series owner—especially driving an E90, E92, or E93 325i, 328i, or 335i—upgrading your rear suspension with adjustable camber and toe arms can significantly enhance handling and tire longevity.
MaXpeedingRods’ Adjustable Rear Camber Toe Arm Kit is designed with the E9X platform and offers a practical solution to alignment challenges. Here’s how to install it.
Tools You’ll Need:
- Floor jack and jack stands
- Lug wrench
- Ratchet and socket set (preferably with torque wrench)
- Allen keys (if applicable)
- Wrenches for locking collars and arm adjustments
Safety Tip: Always work on a flat surface and use proper jack stands. Do not rely on the jack alone.
Installation Steps for the E90/E92/E93:
1. Lift the Vehicle & Remove Rear Wheels
Raise the rear of your 3 Series and secure it on jack stands. Remove the rear wheels to access the suspension arms.
2. Locate the Rear Camber and Toe Arms
Underneath the car, you’ll see two lateral arms per side. The inner mounts bolt to the subframe, while the outer ends connect to the hub carrier.
3. Remove OEM Arms
Unbolt the factory camber and toe arms. You may need to loosen surrounding components slightly to relieve tension. Note how they’re positioned for reference.
4. Install the New Adjustable Arms
Install the MaXpeedingRods arms in place of the stock units. Leave all adjustment collars and bolts slightly loose during installation to allow fine-tuning.
Note: Make sure the bushings are aligned correctly and use the provided hardware where applicable.
5. Adjust to OEM Length (Baseline)
Before torquing everything down, adjust the arms to match the length of the original parts. This will serve as a safe starting point for alignment.
6. Torque Everything to Spec
Lower the vehicle onto ramps or an alignment rack before final torque. This prevents premature bushing wear by tightening under load.
7. Get a Professional Alignment
After installation, a 4-wheel alignment is mandatory. With your new arms, you can now dial in camber and toe settings for optimal tire wear and handling.
Why Upgrade Rear Camber & Toe Arms on Your BMW?
The stock rear arms on the E90/E92/E93 offer limited adjustability. When you lower your BMW or run wider wheels and tires, your alignment can fall out of spec, leading to uneven tire wear and compromised handling.
MaXpeedingRods’ adjustable arm kit offers:
-More precise alignment control for both camber and toe.
-Stronger materials and polyurethane bushings for improved durability and road feel.
-Improved cornering stability, especially on lowered or aggressively driven vehicles.
Installing an Adjustable Rear Camber Toe Arm Kit on your BMW E90/E92/E93 isn’t just about style, it’s about control, safety, and preserving your tire investment. Whether you’re building a street car or a track machine, this upgrade gives you the adjustability the stock suspension lacks.
