These extended front top hats for ND Miata are designed to convert to a true coaxial setup and will add additional compression stroke to the shock. Kitted specifically for Penske 8300 shocks! The top hat design allows the shock shaft to be tucked higher into the body of the car allowing additional room for the shock body to move more than normal. This results in more shock travel before bottoming out and increased 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 full 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 forcing the spring to have nonlinear compression rate. Increased bind leads to higher shock oil temperature, additional wear in pistons and seals, and greatly reduces traction at the wheel. This kit is designed to round out your Penske 8300 dampers with true coaxial, monoball rear upper mounts.

Not designed for use with stock or stock-type springs. DIFtech install kit included to adapt to Penske dampers using Penske spring retainers.

Made in the USA from 6061 billet aluminum. All Diftech supper mounts use high strength FK wide-series bearings with Teflon liners for maintenance free, quiet operation. Customers can also email us for custom install kits for specific racing applications.
