DESCRIPTION
Add more chassis rigidity with these all new front subframe braces. Compatible with the factory splash guards, the front subframe brace quickly installs onto your roadster. These are also compatible with our complete 4 piece under body brace kit!
Why add a front subframe brace? These braces are designed to keep the front wheels tied together and prevent unwanted camber changes under load mid corner.
Not all braces are made the same! These braces are made in the USA, TIG welded and steel construction for the strongest brace possible.
As installed on our Fiat 124 project car:

Front Subframe Brace
Big Improvement!
I purchased these for my 2020 RF Club which already has the OEM strut braces, so I was not sure it would be a big improvement.
I'm happy to report they do make a difference!
-I live on a sloped driveway, and backing out I instantly noticed less flex! (kind of like installing frame rails on an NA/NB Miata)
-The steering felt slightly heavier but it could be a placebo.
-Going over bad roads yielded less NVH in the Cabin!
-Taking corners at low speeds (below 30mph) I could feel the chassis flex less and the front suspension settle in quicker.
-Turn-in response felt more direct
-When I took corners at speed before installing the braces, I felt as though I was overcompensating mid corners and would be "steering too much or steering too little (maybe during mid-cornering the chassis flex catches up to the suspension?) and the car wasn't where I wanted to put it.
-I'm happy to note that taking freeway exits at 70mph+ I can feel the suspension settle in and the steering is more direct. The car steers and gets put exactly where I want it to now!
-I am extremely happy to have installed these before a 3000-mile road trip! I have no doubt it will make driving less fatiguing.
Installation is super easy it's like doing an oil change with extra steps.
------------------------------------------------------------------------------------------------------------------------------------------------------
-Jack up the front of the car
-Using a 12mm socket remove the 9 bolts holding the skid plate
-slide the Skid plate bar in the slot (make sure the hex screws can fit into the holes, and leave them loose for now)
-Using a 17mm Socket and breaker bar, remove the OEM bracing that connects the subframe to the Chassis.
-Install the new braces and leave everything hand tight.
-Replace the Skid plate and make sure the shared bolts for the skid plate and subframe brace line up how you'd like them to.
-Torque the 9x 12mm bolts on the skid plate to 24-28 ft/lbs.
-Torque the 4x 17mm bolts (each side) to 75-80 ft/lbs. (I was worried this might be too much torque, but I couldn't find any torque specs online, this bolt is 17mm and it's an M10. They are rated from 57.3-95.7 ft/lbs. So 75-80 seems fairly safe and likely since I needed a breaker bar to get them off in the first place)
-Tighten down the 2 Hex Screws
-Drive and Enjoy!

I am excited to try out the "4 piece underbody kit" and the "shock tower X brace" when I have the chance to get them!
Install these new braces today very easy install just be mindful to keep everything loose before tightening and torquing down including the under engine cover. I also used my new Ryobi half inch high torque 18 volt brushless impact wrench with the Harbor Freight Pittsburgh tools impact sockets came off like butter. Hand start all the bolts keep them loose then torque down the subframe braces to 75-80ft lb. I stated another reviews I was surprised to see how lightweight and flimsy The Originals were in comparison to these which alone will reduce chassis Flex No Doubt. When the undercover bolts are slightly Loose as they can good to keep an eye on especially if you have anybody doing oil change because they can forget to put in bolts not torque them down or strip out the frame threads. And when they get just a little loose you will notice it freaking noise when you come to a stop showing how much Flex there is in that portion of the subframe. Hope this helps total time of installation was probably about 20 minutes I just rolled the car up on ramps lay down a cloth to lie on use my impact wrench to loosen and take them off and then tighten all the bolts in place and then finally torque them down the subframe bolts
Easy install. I installed the front and rear strut braces and underbody brace before this install so I couldn't tell a drastic difference but I was happy to complete the set.
Right after installed, instant better front end turn in, much better connecting, stable feel compare to stock unit with no other modifications.
I noticed the difference within minutes. I think it only took 10 minutes to install once she was on the lift. The front end seems so much more stable. Well with the price, When you take off the stock parts and see how flimsy it is ( you can flex it in your hands) you will see that this is a worthwhile upgrade. Damn reasonable price.
I wasn't expecting much, but I was really surprised. Rather than skipping over the ruts in the road it rumbles through them. Front end grip is improved, but some understeer is induced. Turn in is also improved.
This in conjunction with the goodwin strut tower 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 help how the car felt under extremely hard braking.
Amazing
Would recommend
Just installed the Front Subframe Brace on my 2020 MX 5. As the other reviewer stated, installation was easy. However, I had previously installed a Transmission Cooling Air Scoop and trimming the corner (driver's side) was necessary to insure a properly fit. Comparing the OEM subframe brace with the upgrade visually gives the impression that the upgrade will give significantly more rigidity. This is another satisfied purchase. Thank you Good-Win Racing!
Super easy install, probably way stronger than OEM bracket, not much heavier, looks great.
If you think about trackdays, you want a stiffer ride or you simply want to preserve overtime your chassis original torsional rigidity, this is defenetely something you want to get! Friends of mine complain about uneven tire shoulder wear after a track day and increase camber to insane numbers to compensate.. With these brackets I never had to..
