Designed especially for classes where a functional torque converter is required, these Circle Track converters are built to maximize efficiency and reduce slippage. These converters can reduce lap times by over a tenth of a second when compared to a stock converter. Other benefits include a rotating weight reduction of several pounds (all removed from the outside diameter, and thus improving engine braking in corners) and reduced transmission operating temperatures.
