So Racetech's calculator for fork springs recommended I get 0.83 kg/mm for the street and 0.87 kg/mm for track use. I'm about 210lb without gear. Would you recommend I go in between with the .85 kg/mm or round down to 0.8 kg/mm?"The labeled rate of the Race Tech springs have been called into question by many sources, although they are still fine quality springs. I rated some 0.85kg/mm labeled springs that I have and they were actually 0.90kg/mm."
"The correct spring is the softest spring available, that is able to support the bike and rider under the hardest of braking/accelerating while still leaving some room for the system to travel if a bumb is encountered in this state."
