Dinan Performance Springs are matched to your BMW's chassis and suspension components to deliver better handling and looks without sacrificing ride quality. Dinan BMW springs are carefully engineered to work within your car's suspension travel and to improve suspension geometry. Spring rates are slightly stiffer than stock and dialed in to reduce bodyroll. A stiffer suspension makes the car more fun to drive and the lower ride height improves the looks by reducing wheel-fender gap.

Dinan spring specs -

• F: -1/2" (12mm)
  
• R: -1/2" (12mm)

Fitment note: When used with stock shocks the Dinan Ride Quality Kit is strongly recommended. The Kit consists of shorter and stiffer bump stops and spring perches that work better with the lowered ride height of these springs. While not explicitly required, less than favorable ride quality and handling may result without them.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. The springs are worth 2 points towards your Dinan badge (Ride Quality Kit is worth 1 point).

The BMW 1502-2002 Tie Bar to Chassis Front Bushing is a key suspension component for classic BMW models manufactured from 1962 to 1977. This bushing connects the tie bar to the chassis, playing a crucial role in maintaining suspension stability and alignment.

Key Features:

1. Purpose:

   • The front bushing connects the tie bar, which helps manage lateral movement in the front suspension, to the chassis. It absorbs shocks and vibrations, ensuring a smoother ride and better handling.

2. Material Composition:

   • Typically made from rubber, this bushing offers comfort and flexibility. However, many enthusiasts opt for polyurethane bushings, which provide greater durability and performance benefits, such as reduced flex and improved handling.

3. Handling Characteristics:

   • Worn or degraded bushings can lead to poor handling, increased body roll, and unstable steering. Replacing these bushings restores proper suspension geometry, enhancing the overall driving experience and stability during cornering.

4. Specific Fit for Classic Models:

   • Designed specifically for BMW 1502-2002 models, these bushings ensure a precise fit, allowing owners to maintain the classic driving characteristics and performance these vehicles are known for.

5. Upgrade Options:

   • Upgrading to polyurethane bushings can improve suspension performance, making them ideal for those who engage in spirited driving or track use. They provide a firmer connection and greater resistance to wear.

6. Installation Process:

   • Replacing the tie bar to chassis front bushing typically involves detaching the tie bar from the chassis. While it can be done as a DIY project, professional installation is often recommended to ensure proper alignment and fit.

Benefits of Replacement or Upgrade:

• Restored Handling Precision: New bushings improve the connection between the tie bar and chassis, resulting in better steering feedback and control.
• Enhanced Comfort: Fresh bushings help absorb road imperfections, leading to a smoother and more enjoyable ride.
• Increased Durability: Upgrading to polyurethane bushings enhances longevity and reduces the need for frequent replacements, maintaining optimal performance over time.

In summary, the Tie Bar to Chassis Front Bushing for the BMW 1502-2002 is essential for preserving the vehicle's suspension integrity and handling characteristics. Whether replacing worn-out bushings or upgrading to a more durable option, ensuring these components are in good condition is vital for enjoying the classic driving experience these BMWs offer.
