986 short shifter...yes or no?

[Hard-Drive]

Recently bought a short shift kit, cheap, off eBay (it's new and looks good quality). However the "101 Boxster Projects" book shows that removing the factory shifter does mean that one of the bushes will be destroyed in the process, so my "if I don't like it I can revert to standard" back up plan may be an issue.

My current shifting action isn't perfect...there's no graunching or stiffness, however occasionally the lever won't "self centre" in the left/right plane.

So my questions are...

1-Has anyone fitted one? Improvement or not? Any regrets?
2-If you are careful, can the bush be reused?
3-If your car was older (75k miles) did it exacerbate any existing shifting issues?

Thanks in advance.!
