I was in an S2000 last year on the auto-x course at race city and he has one of these installed, it's awsome, VERY smooth shifting, all extremely well timed and would be 2x better than a shift light.

that might be handy

 

I thought my Autometer shift light was great!

BTW, before you buy it, verify how you hook it up. You'll need something that is 1 cylinder compatible. Or, a tach module to convert the signals from all the coil packs to a 4 cylinder signal. This will involve rewiring the coil packs. Just giving you a heads up...
