PART NUMBER: 61-2789
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 14 ft/lbs please on the shock tower and firewall nuts.
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.
Customer Installation Photo:
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.
Install took me about 90 minutes, including the time it took me to remove the battery to retrieve a dropped bolt. The GWR forum has a good write-up on a similar shock tower brace, but there's enough going on here that this bar really should come with printed instructions. It looks great and the front end feels more solid when driving down the road.
Stiff, light, and looks great
Noticeable improvement in ride quality vs. Mazda's three-piece shock tower bar
Good access to the damper adjustment on your aftermarket shocks
Where are the instructions?
Would be much easier to install if the EVP control unit mounted on press-in studs, similar to the OEM mounting plate
Spark plug replacement will require complete removal of the shock tower brace vs. removing just two nuts on Mazda's OEM three-piece bar
This is a direct replacement to a Cobalt 3-point tower brace on my RF club. Good-Win-Racing Shock Brace V2 works with a Verus Air Oil Separator (AOS) and JDL 4-2-1 coolant re-route without relocation or rubbing issues. I am happy to say that the V2 works just as good as the 3-point tower brace triangulating and isolating the suspension from the body making the interior quiet.
Hope this helps.
