PS there is no way racing weekly you've run just two spurs.. in 3 years.. unless you ran just a handfull of races per season or if you repalce your parts yearly in the off season.
Actually, I run my stuff more than every weekend because I drive them in the street after work. Plastic works very well and last a long time if you use them correctly. First off, you can't use the Tekno motor mount with plastic spurs. I have been running the RC-Monster mount with a Losi diff fitted into my RC8 for the last two years. I also ran my 8ight with the Losi mount all of this summer and the spur still looks great. I did make a mistake, it has been two years on the same spur not 3. If there are no other failures (diff bearing, motor mount, pinion set screw) there is no reason that plastic spurs can't last a long time.
