Yes, You will want to geat the heavy duty diff gears. Until I did I was changing them every 2 to 3 weekends. My RS4 3 was a rtr
and is now About 3 years old so I an sure there are some differences. I put the wolven graphite shock towere on and threaded shock bodies, so much more adjustable now. I like the MIP cvd's on it to. Don't need to replace as many out drive cups.
Have lots of fun!
