❓ Frequently Asked Questions
Will these increase NVH?
A slight increase in vibration at idle is normal. Under load, most drivers prefer the added precision and elimination of drivetrain slop.
Are these mounts suitable for tuned or high-boost M157 cars?
Absolutely. The billet housings and polyurethane inserts are engineered to handle elevated torque and heat typical in tuned W212/W218 builds.
Do I need new hardware?
OEM hardware may be reused if in good condition. Replace any stretched, corroded, or damaged bolts.
