Project FD RX7 Restomod: Part 17 – McLeod RST 13B Rotary Clutch Update

McLeod RST twin disc organic Clutch for FD RX-7 stock transmission 1x23 splineWe discussed in Part-7 the benefits of multi-disc clutches, which provide similar pedal effort and clamping load to the stock clutch, but gain their torque capacity by having multiple discs.

A really great thing about the McLeod twin disc RST and RXT clutch for the 1×23 spline stock Mazda FD RX-7 transmission is that it is “future-proof”.  If you invest in either of these clutches, they can be sent to McLeod to be inspected and the 1×26 spline center section can be installed when it is time to upgrade the transmission to the Tremec T5 Magnum.  For extreme uses, the pressure plate can also be changed to upgrade an RXT to an RXT1200 without having to buy an entirely new clutch.
