Product Details

Ground Control Coilover Conversion Kits for the 1991-1999 Mitsubishi 3000GT bring true ride-height control to your 3000GT, letting you dial in exactly the stance and corner balance you want instead of living with one fixed factory height. Built around a threaded, spin-to-adjust spring perch system, this kit lowers the car and tightens up body roll for a flatter, more planted feel through corners — all while working with the stock or aftermarket struts you already run.

Every kit is hand-built in the USA and backed by a lifetime guarantee on the complete assembly, not just the springs. Ground Control is the West Coast distributor for Eibach's ERS race spring line, so your car rides on premium springs warrantied against sag and rate change for life, paired with anodized 6061-T6 aluminum adjusters that lock securely under load.

Standard Features

  • Ride-height adjustable threaded spring perch system
  • Eibach ERS race springs with lifetime warranty against sag and rate change
  • Any race or street spring rate available on request
  • 6061-T6 anodized aluminum adjusters with square-cut threads that lock under load
  • Setscrew-secured spring seat holds your ride-height setting in place
  • Upper spring perches insulate the spring for quieter operation
  • Designed to work with stock or aftermarket dampers
  • Adjustment wrench provided where required
  • Hand-built in the USA with a lifetime guarantee on the complete kit, not just the springs
