Questions about 2003 Boxster S Shifter

[PaulE]

Now that I've done 2 HPDE events, I've started to think about the shifter in my 6 speed 2003 S and am considering an upgrade to a short throw shifter, which leads to a couple of questions.

It seems like when I downshift on the track and "think" about the shift instead of just making the downshift, sometimes I have trouble finding the gear (from 4th to 3rd gear, or 3rd to 2nd gear). So I shouldn't "think" about the shift, but would a short throw shifter be more precise in this regard?

Whenever I see pictures of the shift lever assemblies, stock or B&M, the shift lever itself always looks like a flat bar. What I can feel of the lever underneath the boot and below the shift knob is round, not a flat bar. If I get one of these performance shifters, will my stock shift knob fit on the new lever?

Thanks for your input.
