Default fabbed some solid motor mounts.

ok so heres the story. i am switching out a lower mileage engine into my miata. could not get my hands on a set of oem ones soon. the mounts on the car were shot to hell. and my other set were cracking.

so i read some on doing this so i understand somewhat of what ups and downs are of these. but if i do not like them i will order a set of poly ones.

i understand they will rattle and what not. looking for more if anybody has ran them and what performance i can expect will not be driving until tom. just got done with these and installed them with my engine.

so let me know what you guys think of how i did it. how they look and what i can expect BESIDES RATTLING i get that i will get a lot of that. ill deal

I would order some OEM mazdacomp ones and swap them out. The rattling will literally make bolts and **** come loose on your car.

I love the MMR mounts in my NA. It rattles horribly, but the nasty wheelhop is gone and the car hooks way better than you would expect it too. They may not be solid, but they're pretty close.

I can vouch for the mazdacomp mounts being quality, more vibration sure but not enough to **** me off. Much better feel too.

MMR's are still too stiff. Does bad things to the car. I think something in-between mazdacomp and MMR would be perfect.

The shift feel cannot be beat, but when your PPF bolts come loose, your motor mount nuts rattle off, your alternator tension bracket falls off, and your rear view mirror is totally useless at 2200rpm, you'll be reconsidering them. I'm switching my car from MMR to Comp mounts, and resigning myself to the fact that I'll break a set every 6-8 months.

Solid mount on passenger side + Mazdacomp on driver = win

I'd be inclined to run it the opposite, but have never tried a mix like that. The drivers side is always the side that breaks first though.

but the motor compresses towards the passenger side...the driver side gets pulled up.

I've got MMR's on the way, if they are too much I'm going to order one MS mount and try the mix. I have a friend that said his MMR's were rough for about the first 3 months then settled down and are nice now.

Right... and IMHO the stock mounts don't fail because of being compressed. I'm with Crashnscar, MS mount should be on the compression side, solid on the tension side. I suspect you'll find the solid one fails eventually from the movement though.

The idea of the solid mounts is to prevent the motor from moving. I figure the solid would be best on the side that compresses, so the motor still doesn't move when torqued.

either way, I think it's a novel idear.

It seems to me like you wouldnt want to mix them, because the solid mount would probably crack because of its complete lack of flexibility.

well if theses are too bad and i dont like them with the rattleing and all the maintenence involved i will just switch one side and keep one solid.

and i doubt these will ever break under the force of a stock motor. these are strong. they will break something else before they break

Urethane the stock mounts. Cheap, better than oem, not quite as strong as the MMR's.

Solid motor mounts + ANY street driving = Death (aka suicide)
