Ashley, firstly welcome to TM
I fitted the SSL front to my 3.7 very early in its life, (It's a 2018 and was the first customer 5 link) and then later the rear SSL coilovers to the OE factory 5 link as had to wait for SSL to develop the rear conversion
Definitely worthwhile, Richard V6 has the same & will give a more eloquent description of the improvement in ride
