So after doing some research I purchased the H&R springs for my 2016 SHO and had them installed by my dealer. The car was definitely lower by at least 1.5" all around and had the ride characteristics I was looking for. Everyone's happy. Then a day or so later it started occasionally throwing a code and illuminating the service traction control or "AdvanceTrack" as I believe it's called. I called the dealer and have an appointment Monday to have it looked at. But they said it may be a result of the suspension being lowered. They said they sometimes see it with trucks when they are lifted. As much as I see H&R springs discussed, I have never seen this mentioned. Of course, if there's only going to be one person in the whole world to have this issue, it'll be me. Has anyone else ever heard of this? If so, is there a known fix? There doesn't seem to be any loss in ride quality when it occurs. And if I stop and shut off the car, when I restart, it's gone and can stay gone for hours. Any information will be greatly appreciated!
