I was just wondering why this spring is a rear only? It seems like it would be nice to be able to use it in the front also with a new shock rather than new coilovers which are much more expensive.
Also, stock shocks compression and rebound is set to use with stock spring rate. Most of the time when going with longer spring, most manufactures increases the spring rate. Even if you were able to fit the spring on a stock shock, the spring rate would over power the stock shock and deteriorate the shock very quickly.You run into problems with the amount of travel on the struts/shocks. Taller/heavier springs change the range that they work within. You run in to problems with topping out the struts and blowing them out. You get a better end product when you change the struts/shocks with the springs.
