These extended front top hats design specifically for NC MX-5 and MCS dampers 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 included to use 2-1/4" 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. Install kit included for MCS non-remote suspension. Customers can also email us for custom install kits for specific racing applications.

NOTE: Due to the high rise of this particular hat, drilling of the factory shock tower brace may be necessary to allow clearance for shock shaft and access to adjusters.
