Hey guys, i found out that my flywheel is basicly shot. ANd looking through different places etc, i see about 3 choices, the Cast iron (ford racing replacement) Steel, and Aluminum. I knwo the aluminum weighs about 14lbs. And the steel i think is like 23-24lbs... But how much does the Ford racing cast iron one weigh? And is it work spending $220 for the steel, or even $350-$370 for the aluminum one......
