In today's video I tested the Losi Nascar tuning springs with my Zeppin spring tester to measure the spring rates. With the Zeppin tester you can go through a bag of springs in about 5 minutes and you will know exactly what the spring rates are to help set up your RC cars.
There is quite a controversy in online groups that the springs do not measure to the rate posted on the Losi site and I had to see for myself. I bought a pack of springs(LOS-1933) just for this testing.
Testing the spring is fairly simple, I just set the gauge to lbf/in, put the spring in, zero the scale, and compress the spring.
The results are quite baffling and the springs are not close to the stated lbf/in rates that are posted on their web site. I contacted Losi help to see if there was a known issue and they said they will look into it. If you are a Losi mini nascar racer I recommend you test your springs so you know the actual rate you are installing.
Stated Rates:
7.0 lbf/in Springs: Gray
8.0 lbf/in Springs: White
9.0 lbf/in Springs: Yellow
10.0 lbf/in Springs: Pink
11.0 lbf/in Springs: Red
Tested Rates:
6.11 lbf/in Springs: Gray
6.40 lbf/in Springs: Pink
7.23 lbf/in Springs: White
7.74 lbf/in Springs: Yellow
7.84 lbf/in Springs: Black
9.70 lbf/in Springs: Red
