I have a 90 Coupe that's a fun, weekend driven street car (weather permitting) that has a lot of MM goodies on it already.

My next item up is the T/A. I've done research on here and I've read a few members mention the noise and harshness part of it for street use.

Just how bad is it? Is this something that will shake the car loose and make it feel like a complete pos or is it bearable ?

Any input is appreciated and respected.

Thanks fellas!

The NVH is insignificant in my opine. The spherical MM lower control arms added more NVH than the torque arm IMO.

Will you notice it? Yes, from time to time.

The most noticeable thing for me is a whining sound on hard acceleration...could be that my T45 is about to GOOOOO.

It TOTALLY changes the way the car feels in the same way it did when I added the PHB.

First turn you're like WHOA!
Second turn you're like, let's see how much throttle I can give it!

It honestly makes the car more stable on the street too. It's not as harsh and seems to just feel more planted.

Foxes are riddled with NVH right out of the gate anyway. Any MM part I've installed hasn't significantly increased NVH beyond a moderately tolerable level. You tend to just hear the suspension and drivetrain a bit more. But that's all forgotten because exhaust, cam, and stereo.

Heres my take, my car has been gutted and has loud mufflers, and dumps since i was 19....Im 29 now, did the TA add more NHV ?

i

have

no

idea




did the TA increase grip and make the car feel like a 2010+ sports car, yes, it has.


Get the TA, then get the MM k member if you dont already have, you will be surprised how nice a fox can become.

Going from hydrobushings in the front CAs to poly created more NVH than the TA did.

I have found the TA to be unforgiving of driveline angle imperfections. For me, it's a matter of tuning the angles for what speed I'm willing to have it vibrate at, not whether I can eliminate the vibration completely.

I love MM product. This is why im debating on the torque arm- this is a street driven car and I know many will say it's overkill but thus far, I've installed their coil over kit for Bilstein shocks. A arms, lower control arms and the car rides a hundred times nicer than stock. Smoother and firmer. I've since installed the strut brace and front sway bar. Love all the pieces.

I've got a panhard bar in box ready for install.

What bushings did you go with in the A-arms? I'm guessing Urethane as the Delrin bushings are stiffer.

I've got the same in my car, urethane A-arms. If you can tolerate the NVH from those urethane bushings, then the torque arm will be no big deal.

What you need to consider is the rear lower control arm bushings. I've got the extreme duty arms with the Teflon lined spherical bearings at either end, and they're basically like solid hiem joints. With 35 series sidewalls, i feel and hear ever pebble and expansion joint. But all that communication is absolutely what you want when the car is loaded up heavy in a corner.

Can't say for sure, but the urethane rear control arms should be a bit quieter.

Also keep in mind extra chassis stiffening like subframe connectors, k member brace, and strut tower brace will make those suspension impacts ring a bit more true.

Do it, get the torque arm. Just the lower roll center alone will make the car feel totally different, much less like a top heavy 70's boat.

Yes I have the urethane bushings in the front arms and steering rack bushings as well as my end links.

The rear bushing material I'm not sure of? I have the new mm sport lowers.

Main components are in my signature. But the other details are MM Extreme lowers (have the heim joints), MM solid rack bushings, polyurethane spring isolaters, solid transmission mount with polyurethane bushing and pressed in Delrin front control arm bushings. Sure I have some NVH (kind of an understatement) but I wouldn't trade any handling to make it quieter.

Daily driven fox with HD torque arm and XD lower control arms. You will notice a clunk sound when transition from engine braking to drive, but it's not bad. My setup was somewhat sensitive to driveline angle. I ended up setting the pinion angle with a laser bore sight. My setup was SUPER sensitive to driveshaft Ballance. I had a 65 hz resonance that could not be solved with standard balancing practices up to 4000 rpm. I finally tried a Driveshaft Shop 9500rpm balanced shaft and all is well.

If you want a Fox to go around a corner and put the power down, the added NVH from the TA is a small ding to the tremendous performance increase it offers. As already mentioned, a Fox is far from refined on a NVH standpoint, so it somewhat fits the character of the vehicle.
