    Yes. People have been doing it for years on different audi platforms. Not for the faint of heart. The back will take some custom know how but very doable if the wallet is large enough. Avant rear components need some massaging to fit properly

    I think you mean can you make a B9 S4 sedan look like a B9 RS4 sedan. There's a lot more to the RS cars than just front and rear bumpers and fenders. Also, don't forget that the only RS4 model is an avant so the rear fenders will be different.

    I for one would LOVE to see someone do this! I know we don't have an RS4 sedan so I'm open to seeing someone's interpretation of one. Fronts a done deal as the RS4 Avant exist and if someone could follow those fender bulges to the back that would be money. I'm not saying it will be cheap but someone should definitely do it!

    Don’t forget your RS badges


    Seriously, if you go ahead with this please share the build progress. The Pacific German build was wild!

    The front parts will bolt on, but the side skirts, rear quarter panels, and rear bumper are going to get you $$$ wise. When I had my B8.5 I had body shops quoting me 10-15k including paint.

    Easier said than done when your country doesn’t offer the RS4 for sale. People have been doing these body conversions since the b5’s this is nothing new.

    I see your point but I would buy RS5 Sportback rather than destroying car worth 50K.

    It would be easier to self-import and federalize.

    It would be a better value and better performer to build an S4 motor from the ground up to be bulletproof, tune it, tune the suspension to RS4 standards or beyond, and maybe flare the fenders a bit, maybe not the rally flaring, but gentle flaring.

    You will end up with something that will likely be higher performing than an RS4 with capabilities well beyond due to supercharging. There's already a video from Chris Harris and Revo comparing an S4 tuned and an RS4. The drag performance was statistically identical and with suspension, you could likely pull out better handling than with an RS4.

    Outside of that, once again, you could import and federalize one and that is the easiest, most cost-effective option on a car destined to break over and over and over again.

    It would probably be cheaper to just buy an RS 4 or RS 5.

    lol... no... they're not, I've seen the roadmaps... there is no intention to bring anything but the rs6 avant and a6 allroad at this time. The only chance of other future avant models is if this first wave of avants sell well. IF the rs4 ever comes back here, it wont be as a b9
