AW11 KONI Sport Rear Strut Insert (1984-89 MR2)

KONI Sport Rear Strut Insert

For 1984–1989 JDM and 1985–1989 U.S.-Market Toyota MR2 AW11

Overview

The KONI Sport rear insert provides externally adjustable rebound damping for 1984–1989 JDM and 1985–1989 U.S.-Market Toyota MR2 AW11 models while retaining the original strut housing and separate spring arrangement. Two housing-specific versions cover the factory production change in 1986.

Rear gland-nut size determines the correct version: M42 × 1 for 1984–07/1986 production, or M48 × 1.5 for 08/1986–1989 production. Choose Single or Pair for the required housing; a pair contains two matching inserts for the rear axle.

Key Features

• External knob adjustment for rebound damping
• Housing-specific gland nut supplied with each version
• Fits either rear side within the correct housing branch
• Yellow Sport finish with separate retention fittings
• No ride-height adjustment; this is a cartridge, not a complete coilover

Vehicle Fitment

All applications require: original AW11 strut housings.

Toyota MR2 — AW11 / MK1

• 1984–1989: JDM / 4A-GE naturally aspirated
• 1985–1989: U.S.-Market / 4A-GE naturally aspirated
• 1986–1989: JDM Supercharged / 4A-GZE
• 1988–1989: U.S.-Market Supercharged / 4A-GZE

Rear-housing production split:

• 1984–07/1986 production: M42 × 1 rear housing; 4A-GE naturally aspirated.
• 08/1986–1989 production: M48 × 1.5 rear housing; 4A-GE and the supercharged market/year applications above.

Fitment Notes

• Sealed aftermarket struts, coilover assemblies, shortened housings and other conversions are outside this application.
• Original coil springs, upper mounts, spring seats, insulators, bump stops and dust protection are separate assembly components, not included. Serviceable components do not require replacement solely because the insert is being changed.
• These inserts do not support TEMS or other electronic damping controls.
• The two rear versions are not interchangeable. The thread specification identifies the housing-retaining gland, not the piston-rod nut.
• The installed housing controls selection on cars with replacement or swapped struts. A model year alone cannot establish the correct rear insert.
