Perrin or Cusco Engine Mounts and NVH
 

Hi All,

I am getting the sprintex supercharger fitted very shortly and it has been recommended to change the engine mounts - I have been looking at either the Perrin or Cusco ones but I believe that they increase NVH

I was just wondering if anyone has experience with either of these mounts and could guide me in the right direction so as to not increase the NVHJ too much!!!!

I have the Cusco engine mounts and am pleased with it. I was considering going with the Perrin mounts, but I hear you may have to drill or file the hole on the chassis if it doesn't line up, which doesn't sound like a smart move to me. Cusco drops in once aligned and does not require drilling/filing the chassis in order to work as the hardware is reused.

I also used to have the Perrin transmission support, but vibrations were ridiculous with the combination, so I swapped it out for the Kartboy insert. My car also has Perrin rear shifter bushing, Battleversion rear subframe inserts, TIC solid steering rack mounts, and WL differential mounts - so my idea of NVH may differ from yours.

If you get engine mounts, you should get a stiffer transmission mount/insert of some sort if you don't already.

Have you looked into the STi Group-N mounts or the TRD mounts? We have the Cusco's in our Shop BRZ here and while I love them, they do increase the NHV quite a bit. The STi or TRD mounts would be a nice middle ground where it will help reduce movement without increasing the NHV too much.

However with comfort, it really is such a personal preference item that it would be impossible for me to say what would be too stiff or too soft for any individual person, but I hope the above helps.

Thanks,
Rick

thanks for that Rick .... think I will be trying to source either the STi or TRD ones ASAP

any updates ? I am debating on the Perrin or Cusco Engine Mounts...

Is it possible to tell if my car already has STi mounts? I have a 2017 86 and as far as I can tell from pics, the STi and ones I have look exactly the same. So how can I tell them apart? Unless of course the STi mounts are sold separately or don't come stock on any of the latest base cars.

I took a pic of the STI mounts next to the stock 2017 mounts during my install. STI is on the right.

I have the cusco mounts and have been very happy with them. And I don't feel that it increased NVH much for me, I also have a solid trans mount too. And this is with a straight cut gear set.
