When to shift from 2nd or third into first
 

Is there ever a reason or a good time to shift from a higher gear into 1st? I would think the only time someone MIGHT do it is when they're coming to a stop. I know people downshift from 4th into 3rd or 2nd, but 1st seems like it would be too dangerous and you would screw up your tranny. :dunno:

My tib refuses to shift to first, even when double-clutched, till the vehicle speed is below ~ 10 mph (whoops, said rpm earlier, meant MPH...)



The only time I ever wished I could have got it in first from second going faster than that was last Tuesday...



You risk seriously over-revving the engine if you were at the top of second and dropped it to first, and possibly throwing a rod if you got it to slip in from the top of third, if the clutch didn't smoke itself in the process.

In stop and go traffic I shift from 2nd to 1st all the time. I am not sure I understand the question. I don't think I've ever shifted into first from a performance standpoint except for a couple times during autocross if I scrubbed off too much speed to accelerate while in 2nd.

It is worth it, especially for tight autocross style situations. That said, the X3 trans has a really shitty synchro on first, so you best be rev matching or the gearstick goes KRRRR :Shifty:

RD transmission 1st gear was not synchronized in case anyone missed that

Never
