Please note; a modified spring and helix combination affects the final result. Therefore, we cannot provide settings for every application. The test should be performed as follows: accelerate quickly but gradually to avoid track slippage. While accelerating, wait for the RPM to stabilize, then take an RPM reading. If the RPM is too high, add weight; if too low, reduce the weight. Note that surface conditions vary and affect RPM. - Target RPM: 9000 - Team Clutch : Adjustable Ramp Kit Dalton Qa2-76 set to a total of 79 g (use purple Loctite) -Adapt Clutch : Adjustable Ramp Kit Dalton Qa3-65 set to a total of 68 g (use purple Loctite) - A screw head flush with the top of the hole (at the heel) is the most common setting.
