How are people snapping shifters??!!

Unless you're driving a car with dog-engagement internals in the gearbox/transaxle and you're loading the shifter and using the rev-limiter to slot the next gear (Formula BMW styles) then you need to settle right down.

Shifting should be a deliberate, smooth, calculated movement. Yes, you want it to happen as fast as possible, but violently smashing the selectors around in the 'box accomplishes nothing but premature wear and tear or a mid-track failure. You lose more time per lap mucking about violently with the shifter and missing shifts than if you just take the extra moment to get it done right and get your foot back to the floor.

Even garbage Ebay shifters have enough bending moment resistance to survive civil, calculated shifting. In the end it's really your own choice. I like having one on my road car because when I track the car, the throw distance is more similar to the formula car I cut my teeth on. But I've tested many cars without short shifts and the difference is negligible.
