Product Details

Take your handling to the next level! This limited-time Doorbuster bundle combines our performance coilover system with Turner Motorsport polyurethane front control arm bushings for impressive handling gains and a more engaging driving experience. 

ECS PERFORMANCE ADJUSTABLE COILOVER SYSTEM - E30 (51MM)

Our BMW Coilover Line is designed with the daily driver in mind! Our focus was to improve the performance and aesthetics of your vehicle without forgetting comfort. With 32 levels of available damping and height adjustments that are tailored to each car, our coilovers are right in that "sweet spot" of firm and compliant, all while giving you an aggressive look and vastly improved handling.

The ECS Tuning Performance Coilover System provides a sport-tuned, height, damping, and body adjustable suspension with substantial performance benefits using high-quality materials and coatings to replace your worn suspension, all while giving your vehicle that perfect ride height! 

PERFORMANCE FEATURES:

  • 32 levels of rebound damping adjustment
  • Lowering Adjustment of 1" - 4"
  • Spring Rate: 8K Front, 10K Rear.
  • Heat-treated, progressive rate coil springs.
  • Adjustable damping, monotube shocks/struts paired with optimized progressive rate coil springs give your vehicle a road-sticking grip with reduced body roll for exceptional confidence in your vehicle's handling. With your vehicle's new, lower ride height the center of gravity is now moved lower, further improving handling performance
  • Adjustable front bodies allow you to set the ride height while maintaining the correct spring pre-load
  • Adjustable front and rear bodies allow the shock to operate in the correct valving range, regardless of ride height

PRODUCT DESIGN:

  • Strut and shock bodies finished with a durable gloss black powder coat for good looks and great longevity  
  • Threaded portions are zinc-coated for optimum corrosion protection against rain and salt (finish will vary between clear or black zinc coatings depending on availability) 
  • Coil springs are powder-coated Reflex Silver Metallic finish for durability
  • Red anodized, billet aluminum spring seats with locking collars allow for quick, on car, adjustability with the included spanner wrenches 
  • Anodized adjustable sway bar end links with heavy-duty bushings
  • Self-locking, zinc-coated flanged nuts used for shock & strut shaft pins 
  • Zinc-coated strut mount securing nuts included
  • Rear shock adjuster housings are black E-coated for durability 
  • Zinc-coated lower spring perches 
  • Integrated bump stops and dust boots

TURNER MOTORSPORT OFFSET POLYURETHANE FRONT CONTROL ARM BUSHINGS (80A) - PRE-INSTALLED IN BRACKETS

These are control arm bushings from the E30 M3 which can be used on your vehicle for increased castor

The best way to improve handling and response to an E36 is to start at the control arm. The OE bushings are designed more for road comfort than performance, meaning they're soft from the factory and allow significant deflection. When you upgrade to a more stiff polyurethane bushing the control arm has a more direct connection to the vehicle taking the slop out of your handling, increasing steering and braking precision. The Turner 80a bushings are much stiffer than stock making this a perfect balance for an upgraded street car, providing enough comfort for the street with similar control you'd find in a solid mount.

Features:

  • 80A Poly bushing to absorb impact while minimizing unwanted deflection
  • Bushing incorporates internal grooves for grease retention and lower friction
  • Offset design for increased caster for improved straight-line tracking and stability.
  • Bushings are pre-installed in new high quality loli-pop housings
  • CNC machined Delrin center sleeve for high wear resistance, low friction, high precision, and deflection free fitment over the control arm.
  • Bushing grease included
