KONI 1145-1054 Sport Lowering Kit Eibach Springs for 1991-1995 Toyota MR2 SW20

Vehicle Fitment

• 1991-1995 Toyota MR2 (SW20; Base / NA, 2.2L I4, RWD)
• 1991-1995 Toyota MR2 Turbo (SW20T; 2.0L Turbo I4, RWD)

Fitment Notes

• Fits the SW20 platform only - both the naturally aspirated 2.2L (3S-GE / 5S-FE) and the 2.0L turbocharged (3S-GTE) MR2 Turbo variants are supported.
• The KONI Sport dampers in this kit are cartridge-type inserts designed to install into the existing OEM strut housing. The original strut bodies, strut tops, and bearing plates must be reused or replaced separately - they are not included in this kit.
• Strut boots, bump stops, and top mounts are not included and should be inspected and replaced as needed during installation.
• This kit covers the North American (US/Canada) market SW20 MR2, produced 1991-1995. The SW20 was discontinued for North America after the 1995 model year.
• Does not fit the first-generation AW11 MR2 or the third-generation ZZW30 MR2 Spyder - those require separate KONI part numbers.

Features

• Complete 8-piece suspension kit combining 4 KONI Sport performance damper inserts with 4 Eibach Pro-Kit lowering springs - factory-matched and validated together for an optimized, balanced suspension setup on the SW20 MR2 platform.
• KONI Sport dampers (yellow-painted) are externally adjustable for rebound damping, allowing the driver to tune suspension response from a comfortable, compliant street setting to a firmer, more responsive performance setting - without removing the dampers from the vehicle.
• Eibach Pro-Kit progressive-rate springs are specifically engineered for the SW20 MR2, lowering the vehicle approximately 1.0-1.25 in (25-32 mm) front and rear for improved stance, reduced center of gravity, and better aerodynamic engagement.
• Progressive spring rate design provides a compliant initial response over small road imperfections while delivering increasingly firm support under harder cornering, heavier suspension loads, and performance driving inputs.
• Reduces body roll, nose dive under braking, and squat under acceleration compared to OEM or worn dampers, significantly improving the dynamic balance and precision of the mid-engine SW20 platform.
• KONI Sport's user-adjustable rebound damping allows the kit to serve equally well as a daily driver upgrade or a weekend performance / autocross / track day setup - without requiring separate damper units for each use case.
• KONI Sport dampers are manufactured from high-quality raw materials machined to tight tolerances, drawing on KONI's decades of motorsport development in Formula 1, the DTM, and international rally competition.
• Eliminates the factory fender-well gap and lowers the SW20's already aggressive stance for an improved visual profile consistent with the vehicle's mid-engine sports car character.
• KONI Sport dampers are backed by KONI North America's Limited Lifetime Warranty for street use in the United States and Canada.

Product Description

The KONI 1145-1054 is a complete front and rear suspension kit engineered specifically for 1991-1995 Toyota MR2 SW20 models - covering both the naturally aspirated Base and the 2.0L turbocharged MR2 Turbo variants. The kit pairs four externally adjustable KONI Sport damper cartridge inserts with four Eibach Pro-Kit progressive-rate lowering springs in a precisely matched combination, delivering a factory-validated suspension upgrade that improves road holding, body motion control, and driving dynamics while retaining real-world daily usability. The Eibach Pro-Kit springs lower the SW20 approximately 1.0 to 1.25 inches front and rear, bringing the vehicle closer to the ground, reducing the factory fender-well gap, and lowering the center of gravity - all of which contribute to sharpened turn-in response and more confident high-speed cornering on the mid-engine platform.

The KONI Sport damper inserts - finished in KONI's iconic yellow - are externally adjustable for rebound damping through a full one-turn range from soft to firm, allowing the driver to fine-tune suspension response from a comfortable street setting to a more aggressive performance tune for track days or autocross events without removing the units from the car. The cartridge insert design means the KONI dampers install into the existing OEM SW20 strut housings - strut bodies, strut tops, bearing plates, boots, and bump stops are not included and must be reused from the original strut assembly or sourced separately. The Eibach Pro-Kit springs feature a progressive spring rate that transitions from a compliant initial response over everyday road inputs to a progressively firmer rate under hard cornering and performance loads, providing both comfort and capability in a single setup.

The 1145-1054 kit is the benchmark suspension upgrade for the SW20 MR2 platform in the North American enthusiast community, with a long-standing reputation for delivering a balanced combination of performance, adjustability, and longevity. It is suited to a wide range of driving applications - from daily street use to weekend canyon runs and track day events - and is consistently recommended as a step up from the OEM damper and spring combination. KONI Sport dampers are covered by KONI North America's Limited Lifetime Warranty for street use in the United States and Canada.
