2016-2025
PART NUMBER: 61-2789
DESCRIPTION
One piece is MUCH stiffer than the multi-piece alternatives! Now updated to V2 with X design for even more strength. LIGHTEST Shock Tower Brace on the market for ND ... featuring an ultra stiff honeycomb aluminum construction. Just 4.3 pounds! Finished with a durable powder coat finish. The aluminum bar possesses high rigidity and resists flex while stiffening up your engine bay for better steering response and less front cowl shake. Most easy way to reduce NVH. This bar for the ND Miata also connects to the firewall.
Made in the USA, carries a lifetime warranty!
Strong AND lighter!
Many times stronger than the multi-piece factory steel brace and yet lighter too! Factory steel shock tower brace: 4.5 lbs
Other aftermarket steel shock tower braces solve the strength issue of the factory brace, but are far too heavy, the lightest of them starting around 8-9 lbs and they go up from there! RoadsterSport V2 honeycomb aluminum shock tower brace: 4.3 lbs
YES, fits with Edelbrock Supercharger.
If your ND Miata came with a factory steel shock tower brace this is a nice upgrade designed to include access for adjustment knobs when you add adjustable shocks or coilovers.
INSTALLATION NOTES: Re-uses some stock hardware and includes additional hardware needed for install. If your ND Miata did not come with factory shock tower brace note you need to add the Mazda Cowl Mounting Bracket for Shock Tower Brace, our item 60-1238ND. Install of 60-1238ND is a challenge for average DIY owner, typically a mechanic will install the 60-1238ND bracket. If your ND Miata already has a stock tower brace then the cowl bracket is factory installed and swapping out just the shock tower brace is very easy, just 30 ft/lbs please on the shock tower nuts, and 15 ft/lbs on the smaller firewall nuts. Use a torque wrench! They cost $20 or less at Harbor Freight, worth the investment if you don't have one.
Note that due to small differences between cars, rear cowl bracket position, etc. the brace may not sit perfectly flat until it is bolted down fully. To install, set the brace in position and then lightly install all bolts/nuts that hold the brace to the vehicle and then tighten them down evenly. The brace will snug down to the vehicle and the result will be extremely rigid and strong.
Sound tube note:
Many cars do not have a sound tube. For cars that have a sound tube, the sound tube passes around the brace and will rest against it. The brace was designed on a car without a sound tube, and since most folks delete the sound tube, this was not a major consideration. We sell a sound tube delete kit separately on our site that allows you to de-clutter and simplify your engine bay. But if you do want to retain your sound tube you can, the tube just sits there resting against the brace, no harm is done.

RoadsterSport MX5 ND Miata V2 Front Shock Tower 'X' Brace
The Bar is 3/4 pounds lighter then stock. Driving impression: I feel like the cars front end is more solid then before. Steering sensitivity has improved as well. Built quality is excellent, welds are very well made. The bar is extremely rigid. Less weight then stock, looks better and you get performance gains from this product.
worked well at a fair price, easy to install and opens up top shock towers for adjustment.
Extremely lightweight and well made product! Installing it was pretty easy, although it came with many nuts bolts and with no instructions. So it was a little confusing to know which bolts I should replace and which I should keep when installing this new tower. After the install, the difference in reduced body roll has been crazy and it looks awesome under the hood. I highly recommend purchasing, maybe just try and watch a YouTube video to see if there are some instructions on which nuts and bolts to keep from the original shock tower setup.
Like all other already said, the quality, finish and fit of this part is excellent, so why doing another review telling you the exact same thing?
In the end, my order really did not go as planned. The carrier delivered my item but it was damaged. I then contacted GWR and they were extremely responsive, I received a replacement in a more than reasonable time.
I would therefore like to emphasize here a point just as important as the quality of the items sold, namely the after-sales service of GWR which is excellent.
This order was my first at GWR and I can assure you it wont be the last!
Perfect fit ! Excellent build/weld quality.
As others have mentioned, the small screws/nuts are kind of a pain, especially for the ABS/Yaw sensor bracket. For the ABS/Yaw bracket (right side) I tapped 1/4-20 threads into the existing holes and attached bracket with hex socket cap style screws (better quality than button heads). Now if I need to remove the brace in the future, I just unscrew the 2 socket cap screws and don't have to worry with nuts on the backside.
I also painted my brace gloss black for more of an integrated OEM look.
Unlike my two previous NC Miatas, my 2018 Miata GT came from the factory with no shock tower brace. Even so, the 2018 (which was bought used with 22,000 miles on it), felt stiffer from the start. That said, there was still some cowl shake and "looseness" in the front end, especially over bumps and other road imperfections. Since installing this brace, there is a huge difference in the feel of the car. The steering is a bit sharper but more importantly, the car feels so much stiffer now and I can actually feel the stock shocks (for now) doing their job and absorbing the bumps and imperfections without the looseness I previously felt. Not only did this mod improve the feel of the car, but I would assume it will go along way toward preserving the tightness of the unibody tight over time. This is my first performance modification and I'm very pleased.
Installation was fairly easy. I had to install the firewall bracket first. I've reviewed that installation under that product listing. Installation of the brace was fairly easy in spite of there being no instructions included. The most difficult part was removing and reinstalling the two items mounted to the factory shock tower plates. I just kept everything loose until those parts were remounted on the new bracket. It took some finagling (how to say I'm 68 without saying I'm 68) but I got it all back together in a reasonable amount of time. That said, I thought some of the new plated hardware supplied had a cheap feel to it. I would also recommend that shorter hex head bolts be supplied for re-attaching the EVP control unit on the passenger side, instead of the long hex key button head screws that were supplied. Installing these might have been the most annoying part of the job as it requires holding the screw from underneath with a very small hex key and having a deep 10mm socket (who actually has one of those). I ended up using a 10mm wrench for very short turns of the nut while I held the screw. I will likely end up replacing those two screws with shorter stainless steel hex head bolts, making the job much easier in the future when I will need to remove the brace to change spark plugs.
That said, it was well worth the effort.
Pretty straightforward install if you have the factory mounting bracket for the shock tower brace. Just make sure not to drop a bolt or nut as it's quite hard to recover if you don't have the right tools.
Not sure if I feel any difference but I think it made the steering a little bit snappier.
Easy installation, and this is a very high quality yet lightweight brace. Makes the stock club brace seem silly in comparison! Gives me much better access to the adjustment dials in my Zeta CRD shocks. This paired with the coil overs and Progress Anti-Sway bar tightens up the front end very well and makes it drive/handle like a dream. I highly recommend you add this to your ND.
I replaced the factory brace with the Roadstersport X Brace and noticed an immediate improvement in steering response. This brace is stiffer than factory, and weighs about the same as the flimsy tubes. It really dresses up the engine bay. If there is a star rating system on Good-win's site, I'd dock a 1/2 point for not including installation instructions, and having to reuse a couple of nuts I had removed during the removal of the factory brace.
I bought this after getting the Sportster Suspension Kit for easier access to the adjusters for the front shocks. I think it is a must have if you get adjustable front shocks or coilovers.
Install is a little fidly but straightforward. There are no instructions but it is pretty easy to figure out what goes where.
Going slow and figuring things out, the install took me about 45 minutes.
I haven't tracked the car yet since installing (2 day HPDE coming up). On the street it does make the turn-in and handling feel more direct.
If your MX-5 came with the OEM strut tower brace installed or has another aftermarket brace, you might not see a significant improvement in handling; however, if you're like me and didn't have the factory or aftermarket brace installed. You'll notice the car is kept flat and has less front-end flex.
I had previously installed Ohlins coil-overs and an Eibach sway bar, which made for an excellent ride and flat in sweeping corners. Now that I've added the strut tower brace, the turn-in is immediate and flat. It has made the car a point-and-shoot weapon.
I can approach almost any corner at speed, with little to no braking, and the car sticks to the line.
This in conjunction with the goodwin subframe brace will transform front end feel of the car!
Does not feel like the same car after the two parts previously mentioned!
To me this piece specifically seems to improve how the car felt during directional changes, steering feel, directness of inputs, and on camber grip!!
Amazing
Would recommend
Brace and firewall bracket (2016 GTs didn't come with the required anchor posts) ordered at the same time. Took 4 days for the parts to arrive. Since I was going to remove the legacy firewall bracket, I thought I could install a generic oil catch can too, since access to the PVC and intake manifold nipples are much easier with the bracket removed.
Installation of the firewall bracket was pretty easy. Just followed the instructions here: https://youtu.be/uoXXQ34qE_0
The shock tower came well wrapped with assorted hardware for a virgin installation. The tower had good welds and paint. It fit without forcing or compressing, so no pre-loaded stress on the bar. Used these instructions form the forum. https://www.mazdatalkforum.com/viewtopic.php?f=9&t=3812&p=24587&hilit=Strut+tower#p24587
Even though the bar didn't come with pre-installed studs for the control units, I was able to attach bolts to the control units with the included hardware. Then the control units can be attached with just nuts(no need for a third hand).
Piece of cake install.
This is a very nice brace, great workmanship and finish. I had to install the firewall bracket so it was a little bit more involved than just putting on the brace. The firewall bracket was fairly easy to put on, just take your time and it will go great. I did use the instructions on the Moss Miata web site and that helped a lot, they did a great job showing pictures and easy to follow instructions. I do recommend checking the instructions out if you have to install the firewall bracket.
Now getting to the V2 brace, like I said it is a really nice product and it looks great on my Miata. Once I removed the stock strut tower brackets, the V2 dropped right into place. Just be careful when tightening the bolts and you're all set. No issues at all.
I haven't taken my car out for a drive yet so I can't comment on what a difference it makes, but it sure looks great. From what I read it should make a quite a difference, looking forward to finding out.
Very nice product, fit and finish are top quality. But Really! Add the studs for the "control units" on both sides! This product is 4 studs away from being the best it can be! 90% of the install revolves around the lack of these studs.
I had no idea how much of a difference this brace would make but I wish I had it sooner! I have a sport trim that it never came with the factory braces, and I found install including the additional firewall plate incredibly easy. Once installed a rattle that has been plaguing me in the dash went away so I was happy with just that until I took it to some canyons. The steering is more direct, and flex was gone truly allowing the suspension to take over. I have the dual duty Feal coil overs as well as Progress anti-sway bars on my MX5 and am eagerly awaiting my matching rear brace and eventual purchase of the under-body bracing as I was so impressed with how much more FUN my already fun car is with this simple part! It is also nicely powder coated and beautifully TIG welded with good hardware included so when you pop the hood people know you are all business on the twisty roads!
Pretty simple install. Could use some instructions or a video as it comes with some extra hardware. Very light and feels solid.
Possibly one of the easiest parts to install, mind you I am very mechanically inclined. the most difficult part of this install was the bolt holding the bottom bracket of the wiring harness connector on the driver's side in place, this took a wobbly socket adapter. This part is definitely lighter and seems like it would be much stiffer than the OEM brace. I don't have any subjective comparison of this alone vs stock because I replace both upper strut braces (front and rear) along with Progress sway bars but what I can say is that these 4 pieces combined have made this car handle like a dream on stock suspension. Basically no more body roll at all while maintaining a very comfortable ride. This is how the car should have come stock.
I installed it immediately after I received it. Install went smoothly - no issues. The new brace looks great under the hood, but I frankly cannot discern any dynamic difference between this one and the V1. Maybe on the track, but not IMHO on twisty back roads. But it looks great.
I love the look and feel of this brace. Replacement was slightly more involved than expected, but that ended up being a pleasant surprise. My car came with the factory brace so I thought this would be a direct replacement. I didn't notice it in the pictures, but this brace doesn't use the OEM shock tower brackets the stock brace mounts to, so you can remove and toss those too. This one piece unit takes care of everything. The end result is a stiffer front end, less weight, and a dressed up engine bay. This brace is more than I was expecting and I'd recommend it to anyone.
