The Pro Lex GII Short Shift Kit installs on all 2002+ IS300 5 speed models. This kit reduces the throw gap between shifts, allowing for more precise and faster shifting. Not to mention a very racy feel while driving. The shift stalk is also significantly lower than the stock lever.

Notice from Pro Lex Performance: Do not downshift if you are going faster than the maximum allowable speed for the next lower gear. To get on a highway or to pass slower traffic, maximum acceleration may be necessary. Make sure to observe the following maximum allowable speeds in each gear. 1st: 35 mph; 2nd: 60 mph; 3rd: 91 mph.

I had a PLP gen.2 shortie in my '03 for a long time with no problems except for some REALLY loud, irritating rattling. Especially when coasting downhill in gear. Mainly 3rd and 2nd. I heard that this rattling is characteristic to the PLP gen.2 and I tried everything to make it stop but couldn't. A counterweighted shift knob helped a little but not much. The rattling had to go...

I now have a Ralco RZ shortie which I believe is virtually identitical to the B&M. The throws are MUCH shorter and more direct. Not quite as notchy as the plp either. I think the Ralco is superior to the PLP in almost every way. The only thing the plp gen.2 has over the B&M/Ralco is that the shaft itself is shorter and the knob sits a bit lower which, IMO looks a little better.

Personally, I would recommend the Ralco RZ/B&M over the PLP gen.2 any day.

However, I have not heard that the B&M/Ralco RZ can somehow ruin a tranny before... Can anyone confirm this???
