JWT has supplied lightweight performance flywheel alternatives to the original Z & G dual-mass flywheel for over 10 years. However, some people still prefer the more forgiving driving style a heavier flywheel allows, but haven’t warmed to the expense and failure rate associated with dual-mass flywheels. JWT now offers their new conventional clutch and solid single mass flywheel kit that maintains similar inertia to the original flywheel while eliminating the expense and higher failure rate, at about half the cost! Like all JWT flywheels, the friction surface is serviceable allowing it to be reused with multiple clutch replacements for even more cost savings in the future!
