    These extended front top hats for Mazda RX8 are designed to convert to a true coaxial setup and will add additional compression stroke to the shock. This top hat design allows the shock shaft to be tucked higher into the body of the car allowing the shock body to also tuck higher than normal. This results in more shock travel before bottoming out and will increase suspension compliance and traction. The spherical bearing upper mount also eliminates bushing compliance of stock mounts and gives greater control to dampers under high racing loads.

    Non-coaxial upper mounts, while very economical for production and fine for street use, leave a lot of available suspension performance on the table. This can be vastly improved by going to a true coaxial setup that separates the upper mount and spring perch. Non-coaxial upper spring location induces bind in the shock shaft increasing friction on the shock piston and also forces the spring to have nonlinear compression rate. Increased friction leads to higher shock oil temperature, additional wear in pistons and seals, and greatly reduces traction at the wheel. This kit will convert the non-coaxial top hats that come with most coilover suspension kits to a true coaxial set-up.

    Not designed for use with stock or stock-type springs. Diftech install kit required to adapt to a linear race spring.

    Made in the USA from 6061 billet aluminum. All Diftech upper mounts use high strength FK wide-series bearings with Teflon liners for maintenance free, quiet operation. On-the-shelf install kits are available for most popular suspensions on the market and are required for installation. Customers can email us for custom install kits for specific racing applications.
