January 18, 2018 - We recently traded in our Project B9 A4 in favor of it's more powerful sibling, the B9 S4. While we have many modifications planned for this vehicle, one of the first items on the list is our eMMOTION lowering springs, rear sway bar and a new set of wheels.

The eMMOTION springs lower the vehicle by approximately 1.0" front and 0.8" rear, creating an OEM+ ride height while keeping the ride quality as good as stock. The addition of the rear sway bar helps to reduce body roll, improving turn-in and handling capability.

The wheels that we settled on are the RG-R model from BBS. These are part of their forged series, and weigh in at approximately 21 pounds for a 19" wheel. This specific configuration is a 19x8.5" wheel with a 32 offset. As this width is conservative for the B9 S4, we opted for a 10mm spacer all around, bring the effective offset to ET 22. This provides a nice, flush appearance without causing any rubbing. If you need more information on suspension and wheels for your B9 A4 or S4, please feel free to contact us at sales@emdauto.com!
