Cracked on with installing my Race Spring today, took under an hour, dead easy.
Gearbox selector removed
And a side by side of the OEM springs and the thicker Race Springs.
Also installed my pivot ball on the oem shifter which is a 10 min job and can be done insitu. This has removed almost all the slop from the shifter with only a tiny amount remaining which is just wear on the rest of the shifter.
The full Shifter kit includes a new main pillow ball which I've also fitted, this so far seems to have just stiffen everything up, I don't think there was any noticeable play in this part of the shifter anyway... Once I get the car back on the road we shall see.
