I have bought an unused rieger bumper off ebay, When it came I was a little dissapointed.
The bumper isn't made from plastic at all (authentic Rieger).
It's a mixture of fiberglass and plastic. A hit to the bumper would shatter it.
At least it looks much better than stock

It came to me cracked so I filed a claim and sent it for inspection. I got all my money back but
they disposed of the bumper (FedEx). Now I have a car with no bumper.

What do you guys know about OEM rs4 bumpers? Should I just stick with a rieger?

 

if u can afford the oem - thats by far the best looking / best quality..

youll need a good shop to make the adjustments for proper fitment -
but I vote for Rs4...

 

I purchased the rs4 replica from LLTEK, the uberhaus one, not rieger. It took the shop a lot of work to put it in, but I freaking love it. It is also very durable and has gone through many winters and scraped pavement where I was sure it was going to crack and it didn't. However, if I could have afforded it, I would definitely have purchased the oem rs4 bumper.

 

I have the uberhaus RSR front bumper which I also purchased on LLTEK. I think it looks great and is very durable.
