    2015 WRX shifter bushing

    I know Perrin sells a brass shifter bushing for our cars and I hear that it is good, but I'm a cnc machinist and prefer to make things myself if I can. So I just want to know why they are brass instead of any other metal. It seems there is also delrin and aluminum. I could make it out of anything really, I have tons of drop offs that I could easily turn to make one.

    Brass has great low friction properties, as does Delrin. Not so with aluminum. I'd go with either of those two over anything else. Make extras

    I'm pretty sure I have some delrin. But I should have a ton of graphite impregnated nylon. I also have brass lying around. Oh the decisions. Haha

    Doesn't the perrin version have rubber grommet type rings as well?

    It looks like they have 2 o-rings on them. Maybe to keep it snug inside the linkage and help with wear. So instead of the linkage riding on brass it seats on the o-rings. Not exactly sure. Might help with vibration feel also.

    I wonder if ditching the rings would offer a more mechanical feel?

    I'm thinking they would. I'm gonna make them with out and see how that's turns put. It's not like it's hard to. And they are not hard to make. It will probably take longer to get the car on ramps and have everything pulled than to actually make the bushing.

    Well, I made a shifter bushing and it's very similar to Perrins. I could of made it from delrin but I think the brass will last longer. Also the o rings in my opinion are needed for the expansion and contraction of the material or the bushing would have play in it when it got cold or hot.

    Toofa if your close to me I'll let you feel it for yourself. Wow that sounds dirty. Anyway. It's just brass I also plan to make ones out of delrin and some mds nylon I have laying around. So how they work out. It feels better. The stock bushing to me isn't that soft it's not like chewing gum or anything but brass delrin and nylon area all harder of course. But I still think the o-rings are there for when the material expands. So it doesn't get super tight on the linkage and not really want to spin even though I guess it could still rotate on the pin coming from the transmission.

    The nylon I would use is actually mds nylon so it has added lubricity and wear

    It could be worth it hahaha. Delrin is more like a plastic. Perrin is already selling them for 25$ which isnt all that bad. I just like to make stuff that I can instead of paying for it. Kinda like built not bought. I have made and sold stuff for cars before. But there needs to be interest and money to be made. I just dont see a lot of people wanting to buy one of mine when perrin already makes it for a decent price. I could come in slightly cheaper especially if I had a large order but it isn't worth it for me to buy a length of brass and some o-rings when only a couple people want one from me instead of perrin. I havent noticed a tremendous difference after the bushing is installed. yes a difference but not blowing me away. I also only have 600 miles on my car so maybe some more seat time will show the benefits. But I do not like the stock shifter and will definetly be looking for ways to improve shifting feel.
