IRP shifter - input needed
 

Is/has anybody been using the IRP shifter for some time on track/racing? I'm trying to understand if a shifter like this (that is super short/fast) causes accelerated wear on the FRS gearbox/synchros? The shifts are so short, you can't really "slow" down shifting with an IRP.

The gearbox is already a weak point, would be nice to hear if anybody else has been using one for a while without any issues that they know of, so I can feel confident in investing more money in upgraded gearboxes from Jacks. My motor/trans/diff are already solidly mounted, so going to a chassis mount isn't a problem.

Thanks for any input.
