I just got finished with the shifter modifications for the G25 shifter. It increases the spring strength making the shifter have a much firmer shift and it holds in the gear much better. The other mod adds an o-ring to the shifter handle which gives a much firmer feel when pushing down into reverse. This one only costs for the o-ring, the spacer needed can surely be found around your garage or work bench. It's a little tricky getting the spring and ball bearing back in but you should be able to do this in an hour or less. Here's the video for the shifter: [video]http://www.youtube.com/v/eCyt_4luwF0?enablejsapi=1&playerapiid=ytplayer&rel=1&border=0&fs=1&autoplay=0[/video] I did the brake mos about a year ago, it installs a rubber spacer inside of the brake spring reducing travel and giving a much firmer feel to the brakes. You can find them at Nixim: http://www.nixim.com/cart/index.php?act=viewCat&catId=2 The brake mod makes a huge difference, I'll find out about the shifter this Saturday but just practicing it is awesome.
