I’m just going for an OEM+ build. I don’t think it’ll be too stiff or anything outside of minor A/C raffles and maybe vibration at 1200rpms or so. It’ll feel better than the type r. I had a 70a 27won mount on my 2019 civic si and it was like that.
If it doesn’t change much there’s also an insert power flex makes (https://www.powerflexusa.com/shop/p...nl-TTaljj8Idpq1gfXetMIaAg_dEALw_wcB#attr=2826) they have two different bushing types for it as well. That should be a happy medium between stock and full mount.
Type R PN is different. Appears to have more material in the center. It was the same thing with the 10th gen where the si had less material and more flex and type r had more material and less play. It just makes shifting from 1-2 feel sloppy if you go above 4k rpm so I was short shift it.
No, they are different, the Type R is 50890-T60-A21 , while the Sport, Si, and Sport Touring is 50890-3K0-H21
i took off my PRL mount and did the type r mount with powerflex street (yellow) inserts instead. much smoother.
Too much NVH?
yea, i thought so. already have enough rattles as it is.
