LEMFÖRDER 38259 01 Track Control Arm For BMW 3

LEMFÖRDER 38259 01 Track Control Arm – Precision Suspension Component

The LEMFÖRDER 38259 01 Track Control Arm is a high‑performance suspension element engineered specifically for the BMW 3 Series (F30, F80) produced between 2011 and 2018. Designed to replace or upgrade the original factory part, this track control arm delivers superior durability, precise geometry, and seamless integration with the vehicle’s existing chassis.

Key Functional Characteristics

• Exact Fitment: Tailored for the lower rear right side of the BMW 3 Series, ensuring a perfect match to the original mounting points and bolt patterns.
• Material Integrity: Constructed from high‑strength alloy steel that undergoes rigorous heat treatment. This process yields a component capable of withstanding the dynamic loads experienced during aggressive driving or off‑road conditions.
• Corrosion Resistance: The arm is coated with a multi‑layer protective finish, providing long‑term resistance against rust and environmental degradation.
• Load Distribution: Engineered to maintain optimal wheel alignment angles (camber, caster, toe) across a wide range of operating conditions, thereby preserving handling characteristics and tire wear patterns.

Installation Overview

The installation procedure for the LEMFÖRDER 38259 01 Track Control Arm follows standard suspension replacement practices. Below is a concise step‑by‑step guide:

1. Preparation: Secure the vehicle on a lift or jack stands, and remove the wheel to access the lower control arm.
2. Removal of Original Arm: Detach the existing control arm by loosening the mounting bolts. Carefully disconnect any associated sway bar links or tie‑rods if necessary.
3. Alignment Check: Verify that the new arm’s mounting points align with the vehicle’s chassis and suspension geometry.
4. Mounting: Install the LEMFÖRDER 38259 01 by tightening all bolts to the manufacturer’s specified torque values. Ensure that the arm is seated correctly against the steering knuckle and subframe.
5. Reassembly: Reconnect any sway bar links, tie‑rods, or other suspension components removed during disassembly.
6. Wheel Alignment: Perform a professional wheel alignment to confirm that camber, caster, and toe settings are within manufacturer specifications.

Compatibility Highlights

This track control arm is specifically designed for the following BMW models:

• BMW 3 Series (F30) – Front‑wheel drive configuration, 2011–2018 production years.
• BMW 3 Series (F80) – Rear‑wheel drive and all‑wheel drive variants, 2011–2018 production years.

It is suitable for both front axle right side and rear axle right side installations, depending on the vehicle’s drivetrain layout. The part number 38259 01 remains consistent across all compatible models, simplifying inventory management.

Performance Benefits

• Enhanced Handling: By maintaining precise suspension geometry, the arm contributes to sharper steering response and improved cornering stability.
• Reduced Tire Wear: Consistent camber angles help distribute tire load evenly, extending tread life.
• Durability Under Stress: The alloy steel construction resists fatigue from high‑speed driving or heavy loads, reducing the likelihood of component failure.
• Improved Ride Comfort: The arm’s design allows for smooth vertical motion, mitigating harsh impacts from road irregularities.
