When I was racing my NRS4 it became routine to replace 90% of the plastic parts every weekend, saying that I will add that is was raced Friday night, Saturday's would be split between our local indoor carpet track but after that I was on my way to a outdoor TC track where we would run Nitro TC, then Sunday's would be all Nitro TC, 1/10, 1/8 scale.
Here is mine same way it's been sitting since the last race it was used in, just got it running again and working on setting it up for some parking lot racing. I forgot how fast this car was.
