Why does the QA1 package not come with rear springs?

I'm looking at the package for $689.99 but I noticed they do not sell rear springs. Is it my imagination or does QA1 not like the idea of selling rear springs? How do you match the rear springs to the front springs? :confused:

The QA1 rear shocks are designed to offer the best control using stock springs... But can also be used with an aftermarket spring if the lowered look is desired...
If you notice, the only front spring they sell is a 'Drag' spring, so unless you plan on using the suspenision for a drag setup, get a 'shocks only' package, and get the SLP or Eibach or whatever preference spring you want...

If you click on the drop dwn box you will see thunderracing offers three difference choice for the front spring. (a 275, 300, and a 325 pound set of springs)

Those are all relatively light springs for the front, just different levels of drag i believe...
Usually lowering springs and autocross springs are alot higher levels, i think... not an expert on suspensions though

I believe your right, good lowering springs are usually a progressive design
