If you have increased your vehicle's performance, you are likely experiencing more engine and transmission movement. This movement can rob the ability of your vehicle to put down your new-found power properly. The Powerflex Hybrid dogbone insert combines a stiffer lower mount and an insert into one package. This allows for the hybrid insert to be installed without dropping the subframe. The simple installation allows the customer to remove the insert with just hand tools. This is a great bang for buck addition to your 15-21 A3/S3, 16+ TT, 15-21 Golf/GTI/R.
