Supertech Titanium Retainer for Mini R56 - Set of 16 (Fits OEM Spring or SPR-MC56BE)

This is a set of 16 Supertech titanium valve spring retainers, specifically made for the Mini R56. These retainers are designed to work with either the stock OEM valve springs or Supertech's own SPR-MC56BE springs. If you're rebuilding the top end of your Mini R56 engine, these retainers are a key component for ensuring proper valve operation under demanding conditions.

Titanium is significantly lighter than the steel retainers that come stock on many engines. This reduction in weight means less mass for the valve springs to control, which can lead to improved valve train stability at higher RPMs. This is especially important if you're pushing your Mini's engine harder than stock, as it helps prevent valve float and ensures the valves close reliably. The set includes 16 retainers, enough for a full engine rebuild.
