Steffen’s B7 Avant with RS4 Conversion from Norway

B7 Avant RS4 Conversion

This latest featured ride comes to us from Norway and is modded to the max! The owner Steffen bought the car with some mods already done to it, but as many enthusiasts know there is always more to be done.

9 TTRS steering wheel

Steffen started with the interior, scouting some beautiful RS4 bucket seats off ebay.de from a totaled RS4. Steffen tells me they’re probably his favorite modification to the car, which is saying something. To complete the interior, he found a custom TTRS steering wheel with carbon fiber accents which is incredibly beautiful.

RS4 Brakes

Next came the powertrain and handling – the previous owner had already done a handful of performance modifications such as Revo Stage 2+, so Steffen added some RS4 brakes to assist with braking, which works nicely with the OEM themed upgrades he had already.

Then something awesome happened – he found a great deal on the major components needed for an RS4 body swap including front fenders, side skirts, rear doors, and the rear bumper – and thus began the conversion project. He was able to source nearly everything he needed from eBay except the rear inner liner and rear quarter panel.

  1. They’re OEM RS4 panels, not sure if he rolled them as well though. If they’re anything like the S4 fenders, there isn’t a whole lot to roll in the first place…

  2. Thank you all!! Steve, the quarter panel is OEM RS4 fenders, that I finally bought new from the dealer.
    And for an update, I’ve ordered a little sick vinyl wrap I’m gonna try on the car, ordered some custom cut plugs to remove the roof railings, gonna swap my turbo for the Loba LO380, while we’re gonna tweek an extra engine my tuner bought for me. Still more to come!!! And if you have some ideas, I would love to hear them
