New Drivetrain Gear (Tech Talk)

[@KuyaPow626]

Just ordered both of these! I really would love to know the real reason Subaru designed the crankshaft offset like it was. If they wanted it straight it would have been straight, so I wonder what we're potentially sacrificing here. Like the plastic pitch stop that everyone upgrades- the plastic had functionality so that in an accident the engine could "slide down" instead of straight back into the cabin.

We dont have a definitive answer, im sure Subaru does😂 but... our best guess is it was a required saftey measure to pass standards.

Installed the driveshaft lockdown & carrier bushings last night on my 2023 WRX. Just went for a drive to make sure everything was good. I’m getting a slight odor of burning rubber. Is that normal?

[@KuyaPow626]

I think you should look under there and reinspect lol

[@AaronWhitt82]

@@KuyaPow626 It’s fine now. Re-inspected everything and driveshaft is centered perfect & everything torqued to spec. No odd noises, vibrations or odors anymore 🤙🏼

@@AaronWhitt82 You didnt need to change or adjust anything? Never found out the root cause?

[@AaronWhitt82]

@@KuyaPow626 No changes or adjustments made. Been driving for a week now and no issues at all. Thinking maybe since it was new install it had a short break in period or something. Hopefully no carrier bearing pre-mature failures down the road…

[@PERRINPerformance]

Glad to hear that the smell went away. As far as the root caute of the smell id imagine some gunk fell on the exauhst when you poped out the old carrier bushings. Even if the carrier bearing was not lined up perfectly you wouldnt hace any rubbing or grinding issues, so thats my best guess.

will these parts put tohether allow fow more horsepower to the ground? if so then how much?

[@PERRINPerformance]

The large benefit to these especially together, is they will give you a better drive feel. You will feel more of the road beneath you and how your car is reacting to it. These parts fall under the same category as a transmission mount or our engine mounts. The added stiffness of these parts and those alike aid in connecting the car and the road to the driver.

@@PERRINPerformance ok. Sounds good. I already have transmission,engine mount and pitch stop. I like that feel
