Installation doesnt require removal of the driveshaft. The 2-part design clamps around the unserviceable OEM bearing. The old carrier must be removed, so a cutting tool is required. Weve designed this carrier to avoid interference with the factory heat shields, so it has no effect on exhaust clearance.
The exact steps to access the carrier will vary slightly by model, but the removal and installation of the new carrier are the same. The basic steps are:
- C7
- A6, S6 & RS6
- A7, S7 & RS7
Street and Track refer to the durometer (stiffness) of the bushings. Track are roughly twice the durometer of the street bushings. Both track and street are many times stiffer than stock and will hold up to whatever abuse are thrown at them, but the street bushings are better at soaking up drivetrain noise and vibration. Usually both street and track are completely silent and vibration-free, but in cases where there is an underlying drivetrain issue causing the driveshaft to vibrate badly, the track bushings may not be able to soak it all up, where the street bushings can.
We generally recommend street bushings for any car that's not purpose-built for track or overland use, since the street bushings have a much lower chance of transmitting drivetrain NVH to the cabin at high speeds or under heavy throttle loads.
If youre not sure which to go with, the Give me Both! option will give you a full set of each of the street and track bushings. You can use all street, all track, or even mix and match them to find the perfect balance of performance and NVH-absorption.
