The H&R Street Performance Coil Over kit takes the traditional shock/spring package one step further. H&R combines their progressive-rate springs with specially valved shocks and adds height adjusters that let you set the ride height to your own personal tastes. These coil overs are designed for street use with progressive rate springs that start out soft and stiffen as they are compressed. This helps to keep the ride compliant while still giving better handling and balance.

H&R designs each suspension to work as a coil over. This means that the correct amount of travel has been built into each shock. And the shocks are valved specifically for the spring rates to give a tight and controlled ride without being harsh or ultra-stiff. Each H&R coil over is TUV tested and approved and meets ISO quality standards. These are used with the stock strut and shock mounts for a quick and easy install.

The Powerflex Front Control Arm Rear Bushing (Caster Offset) for the BMW F48, F49 X1, and F39 X2 is a premium suspension upgrade designed to improve handling, steering feel, and suspension durability. These bushings replace the factory-installed rubber bushings, which are prone to wear and deflection over time, with high-quality polyurethane bushings that deliver enhanced performance and longevity.

Key Features:

1. Caster Offset Design:

   • The bushing features a caster offset, meaning it slightly adjusts the position of the control arm to increase the vehicle’s caster angle. This improved geometry enhances the car's straight-line stability and helps maintain better steering feel during cornering. The result is sharper turn-in, better directional control, and a more responsive overall driving experience.

2. Superior Material – Polyurethane:

   • Powerflex uses high-performance polyurethane, which is much more durable than standard rubber bushings. Polyurethane bushings resist degradation from oil, road grime, and temperature extremes, making them ideal for both daily driving and high-performance applications.
   • Benefits of Polyurethane:
     • Reduced Flex and Deflection: Offers a firmer connection between the control arm and chassis, reducing unwanted movement in the suspension and improving steering accuracy.
     • Extended Lifespan: Compared to the stock rubber bushings, these will last significantly longer, making them a solid investment for long-term performance and reliability.
     • Improved Handling: The reduced flex and firmer construction mean that the suspension responds more precisely to driver inputs, improving overall handling and cornering stability.

3. Applications:

   • BMW X1 (F48, F49): This model is BMW’s compact luxury crossover SUV. The Powerflex bushings provide better handling, making the X1 more responsive and stable, especially at higher speeds or during spirited driving.
   • BMW X2 (F39): Known for its sportier, coupe-like stance, the X2 benefits from the improved geometry and stiffer bushing, resulting in even sharper steering and enhanced cornering ability, further emphasizing its sport-focused character.

4. Improved Caster Angle:

   • The increased caster angle results in a more self-centering steering feel, providing better directional stability at high speeds, and enhancing control during cornering. This is especially beneficial for drivers who seek a more engaging driving experience or who use their BMW for spirited driving or track days.

5. Performance and Practicality:

   • These bushings aren’t just for performance enthusiasts. Even for daily driving, they offer improvements in steering feedback and stability. The added durability ensures that your suspension components last longer, making it a worthwhile upgrade even for those who don’t push their cars to the limit.

6. Professional Installation Recommended:

   • Installing these bushings requires removing the control arms and pressing out the old bushings. Since the caster offset alters the suspension geometry, a professional alignment is also recommended post-installation to ensure optimal performance.

The Bilstein B8 Performance Plus Kit includes two front struts and two rear shocks. These shocks are for use with lowered springs such as from H&R or Eibach. We do not recommend that you use them with any factory spring, including factory sport package springs. With the increased damping rates from stock you will have much more control over body motions. These will give a much more buttoned down and taut feeling with lowering springs compared to stock shocks.

These shocks fit the following BMWs:

2006+ E90 Sedan 325xi, 328xi, 328i xDrive, 330xi, 335xi, 335i xDrive
2006+ E92 Coupe 328xi, 328i xDrive, 335xi, 335i xDrive

Looking for coilovers that will provide reliability on street driven vehicles but are also capable of feeding your weekend track demon's desire for performance? BC Racing's BR Series coilover kit may be just the thing for you.

BR Series coilovers are the most popular and versatile option offered by BC racing, offering features such as 30-level dampening adjustment (simultaneous compression and rebound control), linear springs where possible, and a minimum of 2 inches ride height drop. To ensure performance, comfort, and quality, all BR Series kits are Dyno tested during the design stage to determine the best valving and spring rates, then installed and tested for a minimum of 6 months. This kit features mounts and brackets that are fully compatible with all stock mounting points and components.

The upper shock/strut mounts are all constructed of 6061-T6 Aluminum for strength and weight savings. BC Racing design 1 of 3 types of upper mounts for each vehicle: Caster/Camber Plates (+/- 3* camber), Camber Plates (+/- 3* camber), and Rubber Mount Plates (NVH reduction). The included mount option for this kit is shown in the kit specs and features below.

Lower shock mounts are powder coated for corrosion protection and constructed of either 6061-T6 aluminum that has been milled from a single piece (fork or bolt eye mount) or of STKM13C steel with all brackets welded robotically.

The included springs come in one of 3 styles: linear, S-barrel, and V-barrel. Linear springs are used in most applications unless limited by the OE design that does not allow the use of linear springs. All spring options are made from SAE9254 steel and have a zinc coating applied under the powder coating for increased spring corrosion protection and long term reliability.

All shock bodies used in the BR Series coilovers use a 53mm shock body (unless noted otherwise) for added strength, performance, and increased fluid capacity. All shocks are then powder coated black chrome for clean styling and corrosion protection.

Specs and Features:

• 9k Front & 6k Rear Spring Rate
• S-Barrel front & Linear rear springs
• Valved specifically to spring style and rate
• Aluminum and Rubber Front Mounts
• Aluminum and Rubber Front Mounts
• Black Powder Coated Components
