One word...
Kartboy.
You've got an '01, so the SPT linkage is pretty much the same as what's sitting in your car now. The only difference is the lever itself. So save $100 and get the Kartboy. Get the linkage bushings too. Before I put the bushings in, I thought " Hey this is pretty cool. Kinda notchy, really quick, and pretty firm." Then I put the bushings in and it gave a whole new meaning to FIRM.
I love it.
