Another way to firm up your shifts is to get rid of the rubber block on the end of the stick.
Get yourself two Poly Sway bar bush's, cut them down to fit into the holes in the bottom of the stick.
I also swapped the stick to the drivers side of the shifter.
The poly bush's firmed up the stick but will still isolate some of the vibrations.
Cheap worthwhile mod.
Not quite as good as my old short shifter but a bit more friendly around town.
Anyone after a T5 SVO short shifter?
i use a rip shift with short throw works very well not realy around town type of car but have had it in traffic no problem
