The ACT XACT Streetlite flywheel for 2017–2021 Honda Civic Type R is a lighter-than-stock Streetlite design that redistributes material for strength, lower inertia and improved heat tolerance. Preferred for street and drag applications, the flywheel is serviceable and can be resurfaced rather than replaced. ACT backs its products with a one-year warranty as noted in the product information.
