Moss Miata


Cobalt lower chassis brace

[2/16/2013] Reviewed by: Dale Norris

Applicable to: '90 - '97 1.6 liter

Black tubular bar flattened on ends with 9/16th bolt holes. Black in color and includes galvanized bolts,nut,washer,lock washer, and thick spacer.

Installation was easy enough with patience and precision Recommend use pinky finger to hold wrench down on top. The effects of this bar are outstanding. The car rides well through the corners and absorbs bumps better while letting your Miata ride like a Cadillac. Also cuts down on cowl shake and interior creak noise. Also quality is of good quality. Not the best but more than enough.

Cobalt front shock tower brace

[10/26/2011] Reviewed by: Evan Bedford -

Applicable to: '90 - '97 1.6 liter

A brace to add rigidity to the front end of the chassis. Attaches to the shock towers and the engine firewall.

I should have stopped when I noticed that installing the brace wouldn't work with a Canadian windshield washer container (space constraints). But I didn't. I ordered a second hand washer container up from the U.S. and installed it. When the Cobalt brace arrived, I repositioned some of the lines and put it in place. Upon loosely bolting the brace to the shock towers, I saw that the firewall bracket was a fair distance away from the firewall (about 3/16's of an inch on the passenger's side and about 5/16's of an inch on the driver's side). (I put a video of it on youtube; just type in "cobalt doesn't fit"). I also found out that a line between the two shock tower attachment brackets was not parallel to the edge of the firewall bracket...significantly. I was considering making up some shims and using slightly longer bolts, but then I also got thinking about the shock bolt attachments. Without the brace attached, there is about 1 or 2 mm's of thread showing above nuts. But with the 4.2 mm thickness of brace that gets attached to them, that leaves a deficit of up to 2 mm's of bolt thread that isn't connecting with the nuts (likely about a 1/4 of the thickness of the nuts). Given that the nuts are supposed to be torqued to 24 foot-pounds, one has to wonder whether the nuts should actually be torqued to spec. Would the threads then be susceptible to failure? (I inspect bridges for a living, and if the end of a bridge rail bolt doesn't have at least one thread thickness showing above the nut, we're supposed to rate the whole bridge rail down). So I decided not to chance it, and I've since sent the brace back to Moss Motors to exchange for some Frog Arms.

Not impressed.

Cobalt Strut Tower Brace

Cobalt strut tower brace

After installation I noticed a definite improvement in the way the car felt. While giving a friend of mine a ride he commented on how the car felt more solid and that's without me telling him about the strut tower brace install. The car does not rattle as much going over railroad tracks and it gives a bit more confidence when taking higher paced turns. If you can afford it get it, it will do your car good.

Light weight and very well built product. Nice and shiny too.

Cobalt Strut tower Brace

[5/5/2008] Reviewed by: Pete Dooley -

Applicable to: '99-'05 1.8 liter

One-piece chromed front suspension strut tower brace.

Arrived nicely boxed and fully wrapped in bubble rap. Product was undamaged and very well finished. Instructions were included and easy to follow.

Installation was simple with no problems except the backing plate was drilled incorrectly and required some filing and grunting to align. Some lines on the firewall needed to be moved around for the brace to fit in place (noted in the instructions). Tightened up the front end and really helps eliminate some of the shaking and loose feel when hitting bumps at all speeds. Got mine on sale (about $175) and I feel it is worth the money for the added structure and firmness it gives the car. I am happy!

Cobalt Polished Stainless Steel Shock Tower Brace

[7/19/2007] Reviewed by: Bruce Rosen -

Applicable to: '90 - '97 1.6 liter 1.8 liter

This is a stainless steel brace that goes from each front shock tower back to the firewall just to the right of center near the top edge of the firewall. It also includes a support piece that fits between the back of the firewall and the flat panel that extend out from the back of the firewall. To install you must drill a few small holes in the firewall and in the flat panel behind the firewall. Thus if you remove it you must leave some small holes in the car.

I installed this as a replacement for a Freedom shock tower brace that just crossed over from tower to tower. This new unit, since it ties the shock towers in with the firewall support, creates a much tightened up front end.

Only drawback I've seen with the unit is that in stiffening up the front of the car it transfers some of the vibrations into the rest of the car that were previously absorbed by the flexing of the front components of the car. This has resulted in a few rattles showing up in the interior of the car (when you hit larger bumps) that were not there before, but I see that as a small price to pay for the tighter handling feel it gives the car.
