Wait for Group N for DD.

[gmookher]

have you ever owned poly mounts?

its not a big deal at all

done commonly and often, using this kind of bushing with interlocking internals

I DD my other urethane mounts, no issue at all, no extra NVH, except at startup, while cranking, its a bit more palpable thru the frame

most cars doing mounts already have a lil extra NVH from exhausts and such, so the fractional incremental amount of extra or added NVH is truly negligible.

perhaps if you were adding these mounts to a bone stock car, with bone stock exh, you may better be able to find those key differences

polyurethane is sex for cars.

Is there a Group N BRZ? No there isn't. There won't be Group N mounts because they needed to produce those for PWRC homologation as far as I understand. There's no homologated BRZ race car in the WRC as Subaru isn't in the WRC...and now we're talking in circles.

Google Isle of man BRZ.

IF there is profit to be had people will make a part to sell.

STi/SPT are making parts for it and it is not a "rally" car.

The BRZ is NOT in ANY homologated series right now. Group-N is related to FIA's WRC. Subaru is NOT in WRC. Subaru will NOT produce so called "Group-N" bits for the BRZ. SPT has NOTHING to do with anything at all. SPT does not make bushings or parts even.

I just ordered a set of these with a rear shifter bushing and some other swag. Can't wait to get this kit in my car.

ps: Love my exhaust on the BRZ.

It does seem to mellow out, but it still has some vibrations. I really don't find it that annoying on this engine compared to the EJ engine with these mounts. I think the engine is much smoother and there are less things that rattle in the BRZ compared to the STI!

I daily drove the STI this way for 2 years and it wasn't that bad. But its all relative to what you like. After driving the BRZ with them for a while, I think that people will find them very appealing in the BRZ because it really makes the drivetrain solid and even more responsive.

Oh and yes, they will feel the same in an FR-S

Those are my next planned mods. Really looking forward to the header....hint hint jeff.

I love Perrin stuff, but OMG the back orders... I guess everyone else loves Perrin products too.

Does this help with the shifter vibrating?

Would likely only make it worse since engine and tranny are more directly connected.

I'm sure one of the new Subaru models(Impreza, WRX, or STi) with the FAXX DIT will be homologated and there will be some interchangeability in Group N parts.
