    Will be purchasing a Whipple Stage 1 shortly but concerned about losing the strut tower brace since my car is a 2015 GT convertible. Will this K-member brace fit on a rag top and if so, will it help counteract the loss of the tower brace?

    • Yes, The Steeda Extreme G-Trac K-Member Brace will indeed fit your 2015 GT Convertible. The brace will definitely add support to the front end of the Mustang.

      Instant Improvement

      So, to start, I'd like to mention that I ran into an issue installing this part. The issue is a result of Ford's production process and not related to this part at all, so no points/stars are taking off for this review. The rear part of the subframe has punched holes, instead of drilled holes. This left the metal pushed in where the spacer is supposed to be placed. Unlike in installtion videos, my spacers did not slide into place easily. So I spent some time trying to bend the open on the subframe so the spacer could fit. Most of my time was spent doing this. After getting annoyed, I aggresively bent the metal and the spacer fit. After that point, the installation went smoothly. After driving the car, the struggle was worth it. Instant reward for putting this part on. The whole front end feels tight and goes into corners no problem. This is the second part I put on the car myself. The installation is not hard and a good learning session for a new comer.

      Xtreme g trak brace

      I purchased the G Trac and rear subframe connector the G Trac brace took about 20 minutes to install I'd say about the same for the rear subframe connector both pieces took just under an hour it feels much better handles like I'm on Rails around corners really sturdys up the car. The parts showed up in excellent condition very easy installation once cars jacked up it took no time at all I'm a hundred percent happy I purchased the Steeda subframe connector and G Trac

      G Trak K member pleased

      Very simple install, maybe 1 hour of labor on jack stands. Install can be completed with out power tools. Just remember to leave bolts loose before tightening up. I have a 2017 performance pack GT, adding the brace in conjunction with tower braces huge diffence in drivability. Turning into turns much stiffer. I have not experienced any NVH. Good product and was my final piece to my suspension upgraded for now.

      Not for the A10

      Was really hoping to box the front-end in with this and the strut-brace, but the main crossmember is about a dime's width from the A10's hard-lines - and there will be some shifting under acceleration and deceleration. Tried using a stack of fender washers to give some room, but that just would put the lateral stress on the welds and not the tubing, so I had to return it. 5 stars for the quality of the piece, though. Manual users should definitely get this.

      Great addition

      The Steeda K-member brace fit perfect, and really tightened up the front of my car. I accelerate on freeway on-ramps without feeling the front end flex at all. I easily pulled away from a BMW M-3 that thought he could keep up with an American sports car. Next on the list are the Steeda sway bars and billet mounts.

      This was the 2nd suspension part added to my 15 mustang gt and all I have to say is that wow u can actually feel the difference once getting it out on. Made my front end alot stiffer and helps most on high speeds. Great add on and worth the money.

      Road course ready

      To add to the previous suspension work, eibach sportline springs and hub centric spacers, I eliminated the famous IRS wheel hop with STEEDA rear sub-frame brace. Enjoyed that so much it was only fitting to install the G-Trac K-Member Brace up front, with the adjustable camber bolts up front and then an alignment, this GT is on rails.

      Awesome

      This g-track does what it says, I have a gtpp with a factory strut tower brace, but thought why not go a little more. It took me an hour total time to install and it was straight forward no issues. I do notice the difference. Next up is front and rear seat bars.

      Brace Yourself!

      This Steeda Extreme G-Track K-Member Brace that I purchased at American Muscle does everything that Steeda and American Muscle claims it will do. You will notice the difference in your ride the first time you go into that corner. There was very little tweaking required during install, almost a perfect fit. One of the best upgrades you can do is to install this product.

      Tightens things up

      Installed over the weekend. My subframe didn't have the tabs but did have the nuts installed. One was not square and doubled the installation trying to get the bolt in. Once in torqued everyting down and was ready to drive. Feels much tighter up front now. No additional harshness out of the suspension.

      Subtle but positive improvement

      This K-member brace provides a decent improvement to handling. It did not negatively impact the ride quality on my non-pp GT, which was my biggest concern. I expect the effect to be more significant when the strut tower brace is installed. As for installation, with a lift and a helping hand it was very straight forward. Ford did leave the blanks partially attached where the rear spacers go. Using a flat head screwdriver I moved them back and forth 2-3 times and they easily popped off at the narrowest point. Much easier and cleaner than using a dremel to cut it off. Like the instructions say, ford no longer puts the upper threaded portion for the forward bolts, however the kit came with additional spacers and nuts for the forward attachment points. I would recommend attaching the forward points first as the rear points have a little play. I tried attaching the rear first and see why people were using a pry bar. I removed the rear and attached the front and everything fit like a glove. Overall this is a simple installation for a benefit that racers and daily drivers alike can appreciate.

      2016 GT

      Great Produce as always with Steeda Parts - "BUT" it seems like Ford did not file off the tabs where the circle opening are. NOTE: 2016 owners will need to file off these little tabs with a Dremel tool in order to get the spacer in. Also I found out if you jack your car up only on one side, it will not line up, I was lucky enough to use my friend's car lift, where you can drive onto the ramps and lifts the car evenly. By doing that, the G-Trac Bar lines up perfectly Other than, It tighten up the Front end.

      Not the biggest handling improvement modification I've done to the front end. It does make the car feel more connected though, just be ready to scrape every speed bump. Had to wrench it into place as well.

      Like others had to tweek it to get it on

      Like others said in reviews, I too had issues getting it to fit. My 2016 Mustang did not have the pre-installed (aka Ford welded in nuts) so had to use the spacers. Two times they fell off inside the cross member while attempting to get it on. Seems they should mill a recess in them so they are captured some. I ended up using spray can of truck bed liner to hold them on. The spacers go up inside the frame almost impossible to get it on by them only balanced there. Next step would have been super glue or epoxy to hold them there. I DID also have tabs inside the real frame that I had to finish snapping off. Which is where I already had truck bead coating out to spray up on the bare metal where these broke off. I installed at same time as the frame-jacking rails. both products should work but were lighter than I felt they should have been for real structural supports. Mustang is parked for winter so no idea on how they will help performance or cornering. M
