Cheaper upgraded motor mount options??
 

Hi just wondering if there are any cheaper upgraded motor mount options? I don't wish to pay $300-400cad for mounts. Are there any OEM upgrade options like out of a 2015+ WRX or STI? Can the factory mounts be filled with window weld?

I was looking and it seems like 2015 WRX engine mounts are a fit, but the part number on Rockauto is the same as an FRS so it doesn't look like it'll be much of an upgrade.

Thanks.

Solid mounts, $100 bucks! Mounts are a do it once, do it right kind of upgrade. Why do you want to upgrade the motor mounts of all things?
I'd highly recommend spending the money to get good mounts- the NVH people talk about isn't just some thing that's really easy to live with, it can be bad enough to make your hands go numb from holding the steering wheel.

Same question??

Hockey Puck?

Thanks. I want to upgrade because I don't like the slop in the factory mounts. Although those solid mounts are probably too extreme for me. [emoji28]

You'd be surprised where "slop" starts and ends. This is what I would do - get white line outrigger bushings and a transmission mount insert from whatever company you like, and see how much it helps.

If you're running a tune from someone, the tune can also affect how poorly the car runs- on/off throttle bucking can be aggressive timing swings or bad fueling.

I'll be frank- my car felt like crap, I hated how it felt during on/off throttle transition. During my car's downtime, I bought an STI transmission mount, torque solutions motor mounts, a carbon fiber driveshaft, all new suspension, sti top hats for the struts, subframe bushings inserts, and the outrigger diff bushings.

I hate drivetrain slop so much, I understand where you're at. I put solid transmission mounts on my car and it helped a lot, but solid mounts aren't good for a daily.

Try what I suggested initially and report back :) when my car runs again, I'll be able to say if my $2,000 anti-slop project worked. I can only rest easy knowing that it will be better than a solid transmission mount. I will admit though, the solid transmission mount got rid of 70% of my gripes

Here's my comparison- https://youtu.be/EsJrs63_ohw

OP. Just be careful, you can go too far and make for one uncomfortable ride in a DD. Ask me how I know on an 04 WRX. If it’s for track, well have at it.

You say you want to upgrade but want to spend less than OEM mounts?

Already have the transmission insert. Helped a ton. Diff inserts are on order. Thanks for the comprehensive answer.

OEM mounts are $80 here. Upgraded mounts are about $300-$500. I was just wondering if there were any alternatives. I do not expect upgraded mounts to be less than stock replacements.

I just watched your video. My tach bounces exactly like yours from the driveline lash. Let me know how your project goes. [emoji106][emoji106][emoji106]

I have used the Megan racing engine mounts for my car for years and been very pleased. They are still rubber but much stiffer than stock and they removed a ton of slop without causing too much nvh for daily driving.

Just remember, the cheap is expensive sometimes.

my mounts on my 2014 are bad. I'm looking to get new ones, but I don't want any NVH so Cusco and Perrin are out for me. I was told if you have mods you shouldn't get oem mounts. Looking at the Megan racing as I like the price and a poster above said he got minimal NVH, but I'm not sure Megan doesnt have the best reputation. I wanted the STI, but they seem to be sold out everywhere. Can anyone recommend me some mounts? what about Torque Solution? is that a quality brand? Thanks!

unless you are heavily tracking your car, Megan will be good enough.

Thanks for responding to me in both threads haha, I really appreciate it. I never tracked my car, so I'll take your recommendation. Megan will add a little NVH, but nothing crazy?

I am not convinced there is a lot of point getting stiffer mounts when you are auto due to the inherent 'slop' they have. That said I haven't driven an auto twin so could be very wrong. I am also not sure why people would say you need upgraded mounts if you aren't FI other than a few specific situations. For instance i have the TRD (which are the same as the STi) motor and g/box mounts because my overpipe would rattle against the steering column on hard left hand turns (right hand drive problems)

Sorry I wasn't clear, no one specifically told me I need to get upgraded mounts. Thats just what I saw from doing research on these forums. So pretty much what you are saying is because I am an auto with basic bolt ons. OEM or just STI mounts would be sufficient?

On my car changing the drive shaft to a one piece made far more difference to driving feel than changing motor and gearbox mounts.

I don't know. Only way to know if you can handle it is to find someone with them and take a ride. Some people cannot deal with any, some people don't care about it at all.

Megan rate them at a 70A on the durometer scale.
Perrin looks to be at a 75A with a different design.
I can't find any info on what the stock mounts are rated at, but you'll definitely notice some engine vibrations at 70a.

I had 70-75A mounts on my integra and the entire interior rattled like a crapbox on startup and at idle.
The trade off was too much for my preference on a street car. Everyone is different but I drive 20k+ km a year and can't deal with that.

STi doesn't list what the durometer rating is but I wouldn't be surprised if it was in the 60a range.

Positive difference?

absolutely. rear end bushings and inserts are great too.

Going to one piece would be my next mod, but I saw a video of someone who's cabin noise was pretty ridiculous. Made me hesitant.

Don't mind the V and H in NVH, but the N can be grating.

Auto really makes no difference in this scenario. The auto doesn't have “slop” and the entire drivetrain still needs to be “loaded” regardless.

I had STI Mounts, whiteline trans insert, rear diff collars, DSS CF DS with zero NVH changes to speak of. Then i added rear subframe inserts and it turned the rear end into a washing machine at 60+ mph so removed those. Then i tried cusco engine mounts turned my front end into a washing machine at sub 3k rpm so switched back to STI.

If you are NA no point really going beyond sti mounts. The more things you add and combine not all of them will play nicely with each other either. I think the above selection is the ideal combination for maximum performance at almost
zero compromise.

Yes, one of my favorite mods for feel. It did increase the noise and initially vibration but that went away once I found the right place to balance it.

it's certainly added volume. It's all personal preference if you can deal with it.

Thanks for this. Unfortunately STI mounts are backordered everywhere. Idk if I should wait or just go with OEM. :iono:

Worth the wait. They're the sweet spot.

Aluminum or CF?

I found a used CF for a good price
