Hey, everybody. I'm Justin with AmericanMuscle.com, and in this video I'm going to be breaking down the new SR Performance Lowering Springs available for your 2015 Mustang.The SR Performance Springs are the latest performance spring offerings for your S550, and in true SR Performance fashion, the price point's coming in a little lower than some of the other offerings available here at AM. That's because the goal of SR Performance is to offer performance and suspension components that will perform as intended, but without breaking the bank. Now, if the S197 SR Performance Lowering Springs are any indication on how these are going to perform, then all 2015 owners definitely want to give these a strong look. The '05 to '14 SR Springs are by far one of the most popular items here at AmericanMuscle.com, and the same qualities that made those so great are carried over to the new springs here for 2015. So, with all of that said, let's get into some of the big points here with these new SR Springs for 2015.Now, you can expect your S550 GT V6 or Ecoboost to be dropped approximately one inch on all four corners using these springs, which, in my opinion, seems to be the magic number here with the new chassis. It's definitely enough to get rid of that ugly wheel gap, of course, but at the same time, it's going to be very daily driver-friendly, meaning you're not going to scrape over every speed bump or pulling into every driveway. If you guys are regular viewers to the channel or to our site, of course, then you know besides looking cool, that lower center of gravity and lower ride height is also going to help you and your 2015 Mustang handle much better, of course. The 2015s, with their new independent rear suspension handle great right out of the box, but it's been my experience that these cars with a set of after-market lowering springs just feel much more playing it to the road.Going over some tech specs quickly with the SR springs...they are a progressive spring, meaning they're going to offer a nice comfortable ride under normal driving conditions, but then will firm up, of course, as they are pushed harder in turns. In addition to that, they will fit both your coupe and convertible S550, in addition to, again, all GTs, V6 and EcoBoost Mustangs.When it does come time to installing your brand new SR Performance Lowering Springs, well, it's a little bit more involved thanks to the new IRS, but really not that bad, overall. If you are attempting this install for the first time, you might want to leave yourself about a half a day in the garage to get everything knocked out. Most importantly here, make sure you have a decent set of tools on hand, and of course, that spring compressor as it will be needed here with this install. As always, guys, I like to recommend, give us a shout here at AmericanMuscle.com, get a Mustang expert on the phone, if you have any more questions about the install or about the SR Springs themselves.So if you're looking to drop your new Mustang, improving not only your looks but also your handling performance, while at the same time not breaking the bank, then be sure to check out the new SR Performance Lowering Springs for your S550, available right here at AmericanMuscle.com.
