Why choose these mount inserts

• Crisper throttle response and improved shift feel
• More direct power delivery with reduced drivetrain slop
• More balanced handling on and off the throttle
• Helps prolong the life of your factory engine mounts
• Designed to fit snugly into the voids of the original mounts
• Can be installed without removing the OE mount housings

These performance inserts use a 70A durometer polyurethane compound to stabilise the engine under acceleration, braking and cornering. By limiting excess movement, they enhance control without a dramatic increase in cabin harshness. Expect a small rise in NVH at idle relative to stock. The firmer the material, the more vibration is transmitted.

Ideal for

• Road and fast-road builds
• Remapped and tuned vehicles that overwhelm soft factory mounts
• Drivers seeking sharper engagement and a more precise gearchange
