We just finished installing the 1LE struts and shocks into a customers 2010 with Hotchkis springs. Ride quality was very nice and just from street driving it felt more controlled and the car seemed to hook up better when taking off. This is a high horsepower car, over 700, and the customers feedback was that the car was easier to drive and it felt more planted when cornering on uneven pavement.
Upon examination his stock struts and shocks were worn out, r/f was leaking, both rears were really weak upon removal. We reused his existing Hotchkis springs.
