I have been using this wheel for a wile and i finally got fed up with the play in it the no resistance and the fifth gear hang up. Enjoy!

G25 Shifter Mods - Illustrated, step by step resource page for every G25 shifter mod
There are a number of scattered threads about different mods for the G25 shifter, so I figured we can all make one thread that categorizes and aggregate all the mods here, and provides all the links and resources for anyone interested in improving their G25 shifter.
Some of these mods have been discussed in great lengths, and some of these are my own that I would like to share. Please feel free to add your pictures, links, ideas, and any new mods you come up with.
Disclaimer
Goes without saying, but just in case…
Performing these mods may void your G25 warranty, or permanently damage your G25 shifter. If you choose to perform any of these mods, please be careful and do so at your own risk!
“No Clicking” Mod
Difficulty: Medium
Old Theory-
This mod reduces or removes the clicking sound when shifting from gear to gear. A piece of foam is inserted into the spring that presses a small metal ball against 3 groves in the metal side plates. Aparently the noise is caused by the spring hitting the metal ball and not the metal ball hitting the metal plate. The foam absorbs the sound and prevents the spring from touching the metal ball, therefore eliminating the click (almost). This also adds some extra resistance to the shifter when switching gears.
Updated Mod by fdkrew-
Removes dead space between ball and plastic housing to remove clicking sound.

Realistic Shifter Resistance
Difficulty: Medium
This mod increases the resistance of the shifter to give it a more realistic feeling.
This is very similar to the “No Clicking Mod”, except that it focuses on making the
spring that locks the ball into place much harder to compress
Although this sounds easy in theory, there are a number of issues to be aware of.
Since the added force on the spring that clicks the ball into place is much greater,
you have to make sure you use some real hard packing material such as plastic or metal,
otherwise over time the spring will find its way back into the housing and the resistance
will lessen.
If the spring is not allowed to compress fully, the ball will not be able to clear the
groves properly, and this will cause extra strain on the metal plates, causing them to move
apart as you shift back and forth. To avoid this, consider bolding on additional reinforcement
to the metal plates to keep them in place. You can think of it as a strut for the housing 
(See photos for pic)
To make room for the strut, there are several notches that need to be filed down from the upper
portion of the plastic case.
(See photos for pic)
In addition, if the plates are moving apart while shifting gears, the potentiometer that keeps
track of the “vertical” gears may not work well if the shifter is switched to sequential mode.
It seem that it is very sensitive to how far it travels to activate the Up/Down gears since in
sequential mode, the shifter doesn’t travel all the way. With this mod, in sequential mode,
when the shifter is positioned in the up or down shift, because the ball will not be in one of
the groves, the plates may have moved apart enough to offset the potentiometer causing it not
to detect the up/down change. In other words, with this mod sequential shifting may not work!
Materials
- Small piece of metal or plastic enough to pack inside the housing of the ball spring

Stiffer Spring Mod
Difficulty: Medium
This mod stiffens the spring in the shaft to avoid accidentally pressing the shifter inwards or in reverse while switching gears.
Replace the original spring of the shaft with a stiffer one. I couldn’t find a stiffer spring or invest the time to go buy one, so in the picture you’ll notice that I added a second smaller spring to add the extra resistance. I imagine a proper stiff spring will work best.
For an alternate method, see the second discussion link.

More Resistance in Neutral Mod
Difficulty: Medium
This mod adds more resistance to the shifter when moving it from side to side.
A rubber band is wrapped around the centering spring to add the resistance.

Reduced wobble in Neutral Mod
Difficulty: Medium
This mod removes the wobbling of the shifter when it is in neutral position, and gives it a stiffer and solid feel.
There are two parts to this mod. The first part is to remove the wobbling caused by the space between the shaft’s plastic housing and the shaft itself. Inserting a small piece of plastic film to fill the space fixes this. (See 1st photo)
The second part is to eliminate the play in the centering spring. The centering spring wraps around the plastic shaft housing and provides resistance as the top portion moves from side to side. The top portion which touches the edges of the centering spring is actually about a millimeter thicker than the bottom portion which the spring uses to grip its other end. Shaving the top portion ever so slightly until the play is removed does the trick.
Materials
- Knife
- 5mm x 15mm piece of plastic film

Reduces Play in 3rd and 4th gear Mod
Difficulty: Easy
This mod reduces the play of the shifter while in 3rd and 4th gear caused by the design of the shifter. Line the inside of the plastic housing where the shifter operates with a piece of rubber or foam. The metal shaft should not touch the plastic housing when it is in gear. It should touch the lining. When the shifter is in 3rd and 4th gear, the pressure against the padding will prevent it from wobbling side to side, giving it a solid feel. This will also add additional noise reduction when shifting hard as the metal will not slam against the plastic.
Materials
- Knife
- 5mm x 15mm piece of plastic film

Different Knob Mod
Difficulty: Easy
This mod replaces the original knob of the shifter with a custom one.
I’ve seen this somewhere, but cannot find a picture. Please help.
Materials
- Flat head screwdriver to remove clip-off stock gear knob cap (I just did it with my fingernail)
- Phillips head screwdriver to unfasten stock knob
- Replacement knob (and adapter if knob does not fasten straight onto shaft - my adapter required a 3mm alan key)
