B7 Audi S4 DTM Rear Bumper

I recently picked up a used DTM Rear Bumper and had it painted and installed to my S4. I had been wanting one for a while, but only recently found one pop up for cheap enough to justify replacing what was otherwise a perfectly fine and undamaged standard S4 rear bumper. When buying new it is quite an expensive part – expect to pay well north of $600 just in parts – and then having it painted and installed should set you back another $400-500 so if buying retail this could easily be a $1,000 dollar mod. While I don’t like to talk here about how much I spend on my car, it was well below $600 all said and done when buying used – a price I was comfortable with now that my “go fast” parts are well sorted out.

The DTM Rear Bumper is an OEM Audi part, so the fitment is fantastic. You have several options when buying one, including dual or quad tip exhaust outlets as well as with or without rear parking sensors (PDC or Parking Distance Control). There is also a Euro (no reflectors) or US option (reflectors included). This bumper was equipped for parking sensors and quad tip exhausts, so it was a perfect fit on my S4. We shaved the reflectors to give it the Euro look, although it was technically a US part. Here are the part numbers if you search for one for your car.

You will also need the rear grilles to complete the look, although I doubt it’s horribly noticeable if you skip this. They run about $60 each, so they’re not exactly cheap given how small and insignificant they are. My body shop ended up making something custom with mesh that looks just as good and didn’t charge me anything extra for it 🙂

• Left Grille: 8E5-807-077
• Right Grille: 8E5-807-078

As with many used parts, eBay can often be a good source of deals so check that out as well…I have no experience with aftermarket replicas (e.g. VIS) of this part, so I generally recommend you stick to the OEM Audi parts rather than fiberglass replicas…

In terms of functionality, this part does little for your car other than aesthetics. The vents in the bumper are non-functional – although they look like brake cooling ducts – they’re not. In theory one could potentially make them functional by drilling out the fender liner and then cutting out the plastic “grilles” but I’m not sure how much benefit that would yield. That being said, it’s a great mod and definitely makes the rear end of the car much more aggressive – so I’m quite happy with it. It wouldn’t be the first mod I’d do to my car, but I’m glad I was finally able to find one cheap enough to justify the cost…
