You are thinking of it right, yes.


Spring rates (higher is ruffer ride=stiffer) will determine the ride. Quality of the company and components will also determine. This is one of those areas that the namebrands have the market. JIC, HKS, and Tein are making the best systems out there.


Tein has nice system developed to lower the ride to your liking and also gives you the capabillity to control the dampening (bumpiness) from the cockpit.


Good Luck. And your BF would be asking for them on his car if he had your car.
