HKS Nissan 180SX Nissan Silvia Hipermax D NOBspec Coilovers. HKS Hipermax D NOBspec Coilovers 80015-AN101 for a 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 Nissan 180SX (R(P)S13 Chassis) and 1988 1989 1990 1991 1992 1993 ((P)S13 Chassis) - HIPERMAX D' NOBspec Coilovers / Includes 2Way Pillow Upper Mount.

Collaboration between HKS and the first D1 champion Mr. Nobuteru Taniguchi created HIPERMAX D’ NOB spec. This is the suspension for “easy drifting.” Stiff suspension is not the only tool for drifting. Mr. Taniguchi and HKS conducted tests on load shift, traction, etc at various levels of drifting skill, and the best specifications for drifting were developed. HIPERMAX D’ NOBspec.brings back the fun of drifting.

• Single tube Design
  A mono-tube suspension structure was utilized for high ride quality and the fun of sporty driving.
• Dustboots Standard
  Shaft damage by rocks and pebbles from bouncing onto the shaft can be prevented.
• PNE Coating
  PNE Coating’s corrosion resistance is 5 times as much as the galvanization. This coating can protect against rust, and its smooth surface requires less force to adjust the ride height than conventional dampers.
• High Flow Linear Piston
  Linear progression piston adjusts oil passages for precise stroke management, resulting in smoother valve movements. As piston speed increases, dampening rate also increases linearly.
• 2 Way Pillow Upper Mount for Front Side
  Wider setting range of a caster and camber can be provided (2 way pillow upper mounts are only for inverted strut type).
• Aluminum Lock Nut & Ride Height Adjuster
  The anti-rust and anti-corrosion for enhanced durability are featured. Using these can cut the unsprung weight.
• Specifications for Easy Drifting
  The best specification to maintain load shift, traction, etc. for perfect and easy drifting.
• 1 Year / 20,000km Limited Warranty
  With the enhanced durability of suspension components allows 1 year/20,000km warranty.
