I am selling my mazdaspeed springs that i never installed, and its still in the box. Selling for 250. Brought it from a Mazda dealer for 280.

 

are they front and back

 

^Yes...

 

with the spirngs you still need the shocks right?

 

You can run your OEM shocks for awhile but they will burn out a lot faster. More abuse is going on.

 

More abuse? I thought they were tested and found to have near stock spring rates. I'm running mine with konis and it's a nice ride.

 

^Any spring that is shorter than stock will put more abuse on the shocks...

 

Yea but spring rate has some to do with it too.

 

Goof price, bump

and OEM shocks will work a bit, but you are lowering the vehicle, so the shocks are going to be more compressed at all times, and when you hit a bump its going to possibly bottom out (if its bad enough) your putting more shock and wear on your OEM shocks, but they will work until you get new shocks.
(from experience)
