Prothane Total Polyurethane Bushing Kit – 1991-1995 Toyota MR2 (SW20) | Black

Restore and sharpen the handling of your SW20 Toyota MR2 with the Prothane Total Kit — a comprehensive polyurethane bushing replacement set that covers the entire suspension and chassis of the 1991–1995 MR2. Prothane’s polyurethane bushings are significantly firmer and more durable than the factory rubber units, eliminating the deflection and compliance that degrades handling precision on aging MR2 suspension. Whether you’re refreshing a high-mileage chassis or building a track-focused SW20, the Prothane Total Kit is the definitive suspension bushing upgrade in one complete package.

Key Features:

• Complete total kit — covers the full suspension and chassis bushing requirements for the 1991–1995 Toyota MR2 (SW20)
• Prothane polyurethane construction — significantly firmer and more durable than factory rubber bushings
• Black finish — clean appearance that suits both stock and modified SW20 builds
• Eliminates bushing deflection — reduces the compliance and vagueness that worn rubber bushings introduce into the suspension
• Direct replacement — designed to fit factory suspension mounting points without modification
• Greaseable design — Prothane bushings include grease fittings or grease grooves to prevent squeaking and extend service life
• Made in the USA — Prothane products are manufactured in the United States

Performance Benefits:

• Improved Handling Precision: Polyurethane’s higher durometer eliminates the bushing deflection that causes vague steering response, body roll, and inconsistent suspension geometry on worn rubber bushings
• Consistent Suspension Geometry: Firmer bushings maintain suspension alignment and geometry under load, keeping camber, toe, and caster closer to their set values during hard cornering
• Reduced Body Roll: Stiffer bushing material reduces the compliance that allows the suspension to flex under lateral load, improving cornering composure and driver confidence
• Long-Term Durability: Polyurethane resists oil, ozone, and UV degradation far better than rubber — outlasting factory bushings significantly in both street and track use
• Complete Refresh: Replacing all bushings simultaneously ensures consistent compliance characteristics throughout the suspension — no mismatched old and new bushing feel

Specifications:

Fitment Information:

• 1991–1995 Toyota MR2 (SW20) — all variants
• Note: Verify your specific year and model before ordering
• Installation: Professional installation strongly recommended — full bushing replacement requires suspension disassembly and a press for most bushing locations
• Alignment Required: Full alignment required after installation

What’s Included:

• Complete set of Prothane polyurethane bushings for the 1991–1995 Toyota MR2 (SW20) — all suspension and chassis bushing locations
• Prothane grease for bushing installation and lubrication
• Installation instructions

Installation Notes:

• Professional installation strongly recommended — most bushing locations require a hydraulic press for removal and installation
• Clean all bushing housings thoroughly before installing new bushings
• Apply the included Prothane grease to all bushing surfaces during installation to prevent squeaking
• Full alignment required after installation — do not skip this step
• Allow bushings to settle for 500–1,000 km before final alignment check
• Re-torque all suspension fasteners after the settling period

Polyurethane vs. Rubber Bushings:

Factory rubber bushings are designed for comfort — their compliance absorbs road noise and vibration, but also allows suspension components to move slightly out of their intended positions under load. On a mid-engine sports car like the SW20 MR2, where handling balance and precision are critical, this compliance translates directly into vague steering, inconsistent cornering behaviour, and reduced driver confidence. Prothane’s polyurethane bushings are significantly firmer, maintaining suspension geometry more accurately under load while still providing enough compliance for street use. The trade-off is a slightly firmer ride and potentially more NVH transmission — an acceptable compromise for any driver who values handling precision over isolation.

The SW20 MR2 Platform:

The 1991–1995 Toyota MR2 (SW20) is one of the most celebrated mid-engine sports cars of its era — a lightweight, rear-wheel-drive platform with a turbocharged 3S-GTE or naturally aspirated 5S-FE engine mounted amidships for near-perfect weight distribution. The SW20’s handling is famously rewarding but also demanding — its mid-engine balance makes it exceptionally responsive to suspension tuning. Worn rubber bushings are one of the most common causes of handling degradation on aging SW20s, and a complete Prothane bushing refresh is one of the highest-impact suspension upgrades available for the platform.

Why Prothane?

Prothane has been manufacturing polyurethane suspension components in the USA since 1982. Their Total Kit lineup covers hundreds of vehicle applications with complete, vehicle-specific bushing sets engineered to replace every rubber bushing in the suspension and chassis. Prothane’s polyurethane formulation is designed to balance performance improvement with street drivability — firmer than rubber without the harshness of solid mounts.

Perfect For:

• 1991–1995 Toyota MR2 (SW20) owners refreshing worn or degraded factory rubber bushings
• SW20 builds seeking improved handling precision and suspension consistency
• Track day and time attack builds wanting a complete bushing upgrade in one kit
• High-mileage SW20s where rubber bushing degradation is contributing to handling vagueness
• Anyone building a performance-focused SW20 who wants consistent suspension geometry under hard driving

Pro Tip: Replace all bushings simultaneously rather than spot-replacing individual worn ones. Mixing old rubber and new polyurethane bushings creates inconsistent compliance characteristics throughout the suspension — the Total Kit ensures a uniform upgrade across the entire chassis.

Note: Full alignment is required after installation. Polyurethane bushings are firmer than rubber and will transmit more road noise and vibration into the cabin — this is normal and expected for a performance bushing upgrade.
