    Juice Not Worth the Squeeze

    Looks better and is lighter than the factory junk but that's about it. It took a lot of work to get the support to line up with the Steeda sway bar I installed last year. Broke one of the x-mas tree clips for the brake line when removing it from the factory support, not that it matters since the holes don't line up with the brake line anyway. I didn't feel comfortable bending the break line to fit the holes in the Steeda support. The nylon ties to attach the splash shields were not included in the package and it is a rinky dink support method anyway.

    This support is just what it says it is. Install is easy especially with a lift. Took about 35 min to install and fit was perfect. As far as performance goes unless you are replacing K-member and other front end lightweight components, you will not notice any performance gain but it looks nice.

    10 pounds lighter as adverised!

    There are other radiator supports out there, but Steeda's is made of chromolly and gives you the full weight reduction. I had hesitated purchasing this for 3 years now because the whole idea of securing my splash guard with zip-ties always struck me as sort of mickey-mouse. It turned out to be no big deal. There are other fasteners on the sides of the splash guard that are retained which hold it in place. You will likely only see a performance gain when installing this with other mods which also transfer more weight to the rear.

    Shave some weight

    Adding some mods to underside of my 2013 boss 302 that would add some weight. Did the steeda lower rad support to help offset it. I weighed the stock and the steeda support and found a difference of 10lbs. So saving 10lbs of weight off the front end with good looks was worth it. I would recommend the Steeda lower radiator support for looks, strength and weight savings.

    steeda radiator support 2011 GT

    Fit was perfect. Easy install. Nice quality and very lightweight. My scales were showing a legit 32 pound drop from front if you lose the sway bar, keep the z-brace. Quality product and i like the fact the sway bar brackets are there if you decide to use them. I will try it both ways with and without!
