And this is your potential problem. What is the next weakest link? U-Joints in the drive shaft? Axles?

^^^THIS

Mine are working like a charm. I still love actually finding 3rd gear.

I have the solid mounts ICS use to sell, I like them a lot on the track, they only make the car rattle at idle, my engine is very well balanced so I cant speak for a stock engine, but defiantly makes your car louder inside.

Not sure about the comparison to a miata, but I ran the solid mounts on my srt and never had a problem. I'm using the comp mounts now and they don't compare anywhere close to the solids I had in the neon.

Advantage: Excites the girl in the passenger seat.

Disadvantage: Everything else. They'll rattle your stuff so loose that your motor will stop running. My A/C button would keep falling off when WOT in 2nd gear too.

My Dad used to race Porsche's in the early 90s and he said that is the roughest car he's ever been in.

Turbo_4 11-02-2009 07:19 PM

hmmm....well glad that I got the comps!

miata2fast 11-02-2009 07:19 PM

I made a pair of solid mounts, and I promptly took them out. I still drive it on the street, and I could not believe how much it rattled. If it is an all out race car, I could see it. If it is not, you may want to think twice about it.:2cents:

looks pretty descent but a lot of vibration no?

The driver side is the one that breaks all the time.

A chassis builder told me to never mix solid and rubber mounts. I had a Camero with solid transmission mounts and rubber motor mounts, and the transmission bell housing kept breaking. I put all solid mounts in and it cured the problem.

It was a track only car and I excepted the rattling. I would say that the Miata rattled about as bad as the fire breathing drag race only Camero. I thought the damn dash was going to crack.

Stupid microphone doesn't do it justice though.

I had a Jeep that had solid mounts. 300hp, 350 turbo tranny, gears axles, jacked up with the works.

Before i bought it,The guy made the mounts cut a square piece of tire and placed it between the motor and the mount used like a washer. Believe it or not. It worked well. I seen that and thought how ghetto when evrything else was so refined. But it worked well.

don't hate on my genius.

well i drove the car today. and the vibration is not that bad. my dash rattles but its loose. just need to go thru the car and get all the little rattles out.

it shifts great and the gas pedal is on off you can really feel the engine now. if you down shift and rev match its so good.


only problem is my car wont idle right lol so it does rattle a decent amount seems to be the worst around 2k any higher or lower then that its not bad at all.

This will be a weekly thing for you. Get used to it.

Fixed

turbotyla 11-03-2009 11:31 PM

in all honesty if you guys have not driven in the car. it is not near as bad as you guys are making it.

like you guys are being so dramatic its funny. at idle i can barely even tell the difference. and i will get most of the rattles out. my father used to install stereos in cars that rattled way more than these mounts there a little tricks to it.


the only part the dash starts to rattle is 2k to 2300 other than that its a slight hum in the car and the throttle response is awesome and i also put a f1 clutch in and it grabs decent so with the mounts and the new clutch i really like how the car drives now.

so i needed to tear my whole interior out anyways because i am replacing the carpet and dyno matting the fire wall and trans tunnel. and after re installing i doubt there will be anything to complain about.

i like it and i am going to stick with it.

18psi 11-03-2009 11:34 PM

That's all that matters:D
After all its your car. You like the rattles and vibration, power to you.

turbotyla 11-03-2009 11:38 PM

true but i posted this thread to get an idea before i installed and everyone freaked out and was saying how bad it would be.

in all honesty its not bad at all. is there more vibration yes. and rattling yes.

but my car was not the smoothest to begin with im slowly trying to restore/modify this car i got it pretty much from death and am going thru it end to end.

so the interior is the next step. so if after i reinstall the interior and some things i cant stop rattleing i might buy some poly ones but as of right now the only complaint i have is somthing i had to fix before these either way

magnamx-5 11-04-2009 12:10 AM

meh i like my mmrs they might make the rearview rattle but ohwell the shit stays put and i nvr miss a shift cause of the tranny twisting.

triple88a 11-04-2009 01:20 AM

Just curious, why doesnt any one use traction bars to cure the wheel hop instead of trash everything else?

Add some traction bars, add some stiffer springs and you have your self a smooth as butter burnout/takeoff.
