Innovative Mounts 113450-60A Replacement Engine Mount Kit for 01-05 Mazda Miata

Vehicle Fitment

• 2001-2005 Mazda MX-5 Miata (NB2 chassis | 1.8L BP-Z3)
• Compatible with any NA or NB chassis fitted with the 2001-2005 MX-5 1.8L engine

Fitment Notes

• Designed for the NB2-generation MX-5 Miata (2001-2005) equipped with the 1.8L BP-Z3 engine. Also fits any earlier NA or NB1 chassis that has been fitted with the 2001-2005 1.8L motor - mount fitment follows the engine, not the chassis year.
• Does not include a transmission mount. This kit covers the left-hand (LH) and right-hand (RH) engine side mounts only. The factory transmission mount is retained and not replaced by this kit.
• Uses stock OEM hardware - no additional hardware is included or required. Installer will reuse the factory bolts throughout.
• No notching, trimming, or hood modifications required for installation. The mount design accommodates stock hood clearance at both mounting positions.
• Height-adjustable design: the mount allows the engine to be raised or lowered by 3/8" from stock ride height by selecting the appropriate mounting point - providing a useful option for builds requiring minor drivetrain height correction.
• 60A durometer polyurethane is the softest bushing option Innovative offers and is recommended for street/daily-driven applications up to approximately 250 hp. Higher HP or track-focused builds should consider the 75A (250-400 hp), 85A (400-500 hp), or 95A (500+ hp) variants.
• Once installed and bolted down, mounts cannot be returned or exchanged - bolt impressions will be visible on the bushing. Confirm fitment before installation.
• Professional installation by a mechanic or automotive specialist is strongly recommended.

Features

• Direct factory/OEM replacement fitment - bolt-on replacement for the stock rubber-filled engine mounts, requiring no chassis modification or fabrication
• 60A polyurethane (red) bushings provide a meaningful step up in engine stability and drivetrain response over the fluid-filled OEM mounts while transmitting only minimally more NVH than stock - the optimal balance for street-driven Miatas up to 250 hp
• Unique no-tear bushing formula is designed to resist degradation from engine heat, oil, and the torsional loads generated by performance driving - engineered to outlast OEM rubber mounts by a significant margin
• By eliminating the factory fluid-filled rubber mounts, these Innovative mounts reduce engine movement under acceleration and braking, improving shifter feel, reducing wheel hop, and providing more consistent throttle response
• Height-adjustable mounting: select from two mount positions to raise the engine 3/8" above stock - useful for small engine bay clearance adjustments or mild chassis leveling on modified builds - all without requiring hood trimming
• Black powder-coated solid steel mount body provides long-term corrosion resistance and structural durability far beyond the thin-gauge stamped steel of OEM mounts
• CAD/CAM designed and stress analyzed at Innovative's North Carolina manufacturing facility for precise fitment and structural reliability under performance loading
• Manufactured entirely in the USA - designed, cut, bent, welded, powder coated, finished, and packaged at Innovative's facility in North Carolina
• Covered by Innovative Mounts' Lifetime Warranty against defects in material and workmanship when purchased through an authorized dealer

Product Description

The Innovative Mounts 113450-60A is a direct-replacement engine mount kit for the 2001-2005 Mazda MX-5 Miata NB2 equipped with the 1.8L BP-Z3 four-cylinder engine. It replaces the factory fluid-filled rubber side mounts with solid steel mounts fitted with 60A durometer polyurethane bushings - a street-optimized upgrade that improves drivetrain stability and driving response while maintaining acceptable NVH levels for daily use. The kit includes the left-hand and right-hand engine side mounts only; the factory transmission mount is retained.

The OEM rubber mounts in the NB Miata are fluid-filled and compliance-engineered for noise suppression - a design that softens the driving experience but also allows more engine movement under load than performance driving demands. That engine movement under acceleration and corner exit translates directly into imprecise shifter feel, increased wheel hop under power, and a less direct throttle response. The Innovative 113450-60A addresses all of these by eliminating the fluid-filled compliance and replacing it with 60A polyurethane - a material that holds the drivetrain far more firmly in place without the excessive vibration transmission of harder bushing compounds. At 60A, these are the softest option in Innovative's lineup and are specifically recommended for street-driven Miatas up to approximately 250 hp. Owners building higher-output or dedicated track applications should consider the 75A (250-400 hp), 85A (400-500 hp), or 95A (500+ hp) variants.

A practical bonus of this kit's design is its built-in height adjustability - by choosing between the mount's two bolt positions, the engine can be raised 3/8" above stock height without any hood trimming or clearance concerns. This is a useful feature for builders making minor drivetrain height corrections on modified NB chassis. All installation uses the factory OEM hardware, which is not included in the kit. Mounts cannot be returned after installation once bolt impressions are visible. Made in North Carolina and backed by Innovative Mounts' Lifetime Warranty when purchased through an authorized dealer.
