When I got home i tried them compared to the tamiya spring, and was pleasantly surprised with how balanced the car was. Any other time I have tried the same spring all around balance was compromised and it was not fun to drive. I would slot these in between a white/blue(Tamiya) such as a Tamiya silver(TA05) but more progressive. I would have liked to try this with steves car at the TCS north american finals but as we all know that isnt allowed. Keep in mind this may work in low grip but most likely not once it gets high.
