Hey guys. Well I'm new to the whole clutch and flywheel thing and was wondering if you guys can give sme advice on it. I'm planning in getting a 8lbs flywheel with a competition clutch and was wondering if I needed a rebalance since the flywheel is so light. I'm not to sure about this but one of my friends said that anything under 11 would need a rebalance but I wasn't too sure what that is.
