Hello everyone.

I just recently bought an 03 Audi A4 1.8T Quattro. I have owned and built multiple e36 M3s over the years. I am having difficulties finding parts for the Audi. There is a clunk(rear differential/driveshaft area) when accelerating around the 5500-6300 rpm range in first gear. I also experience some noises when making hard left turns and weight is distributed to the right side of car. I am attributing the noise to the RTABs. I would like to put Powerflex RTABs on the car but I cannot find them(I found them for the rear diff.).

I have plans to build this car as my daily/occasional track car. If anyone can please refer me to some reputable companies for aftermarket parts I would greatly appreciate it.

Thanks,

Brandon
