What is the difference between this coil spring, and all the others listed that fit my 2016 VW Jetta "S" ? The difference is a series of colors on the coil springs-bit I am replacing a set of lowering springs, and the originals are long gone before I bought the car. Is there any reason a pair of these would not work on my car ? Thanks. Mike. 217-971-2676 hallmikes@aol.com
