Rotrex superchargers utilize a unique traction drive system that sets it apart from other centrifugal-style superchargers. For best performance, Rotrex recommends replacing this fluid every 50,000 miles. This bottle of traction fluid is plenty enough for one supercharger service (typically 750ml).

This weighted shift knob makes shifts faster and the extra-large globe shape encourages over-palm shifting. The Black Forest Industries Billet Knob weighs in at 8.8oz (250g), about twice as much as a stock knob and a little heaver than the BMW ZHP knob. The heavier knob amplifies the pendulum motion of the shift lever resulting in smoother and faster shift times. BFI has designed this knob for BMW and VW fitments to fit snug on the shift lever and be secured with Allen set screws. They were careful to reduce tolerances compared to universal knobs. The overall height of the BFI knob is the same as stock anatomic knobs (some BMW M/Performance models have a stock knob that is shorter than this one).

Included with the BFI Billet knob is a matching BFI crest shift emblem. A 5 or 6-speed pattern emblem is available separately.

Choose from soft alcantara or perforated air leather with either a silver or black anodized base.

Adjustable Rebound & Compression Damping 

Want full control? The KW V3 gives you multiple settings for both rebound and compression. You have full access over ride comfort and handling to dial in that perfect setup. Race teams rely on adjustments to get that perfect lap time and having shock controls at your fingertips is key. KW V3 features -

  • Separate adjustments for compression (14 positions) and rebound (infinite settings),
  • Stiffer springs over stock for less bodyroll than the standard suspension,
  • Stainless steel strut/shock bodies and composite spring perches for superior corrossion resistance,
  • Individually height-adjustable - Front = 10-40mm lowering; Rear = 5-35mm lowering,
  • TUV approved lowering range and operation,
  • Expert engineering and design for ease-of-use and long durability,

Whether you track the car often or only use it for backroad carving the V3 will give you the tools to set up an ideal handling condition. You can crank it up for smooth and fast surfaces or soften it for city or rough roads. Since each shock is 2-way adjustable you can alter the front-rear balance to account for brake dive or squat during power application coming out of the corner. You are in total control! 

Coil over suspensions are better engineered suspension options compared to a standard shock + spring package. Since the springs and shocks in a coil over are designed by a team of engineers to work together, there is much better suspension travel and more precisely tuned specifications for spring and shock rates. Using separate shock and spring specs may result in premature coil bind or shock bottoming. And most coil over kits offer more features than the traditional packages. Coil overs are also more useful when larger wheels/tires are used because you can precisely set the ride heights to clear the new tires. 

Fitment Note: Wheel spacers may be required depending on wheel/tire sizing and ride height setting.
