Agreed just no need to replace all that. Mugen stuff lasts a very long time, which is why a lot of long time r/c racers race Mugens.
I just rebuilt my buggy, replacing anything that showed signs of wear.
Only needed to replace the front lowers from rock chips, the rest were absolutely perfect, and have a TON of racing on them. Diffs were all fine with lord knows how many gallons on them, the steering shafts plastics were worn next to ackerman and had slop so they were replaced, but that was about it.
