Does Shock need to be change when you changing to sport spring?

[Slaander]

Just wondering does the stock shocks will do fine with sport springs?

[PhatRoyale]

Yes. But they will blow out faster and are not meant to run compressed.

If it's a mild drop then it would be fine.

1" to 1 1/4" drop is no problem on stockers as long as you don't have a lot of miles on them and you don't slam the upper mount into the top of the shock. If they are getting weak now, the drop springs will generally eat them up because the shock can't stop the spring motion from cycling. The shocks don't know whether they're compressed or extended, so the old tale of wearing them out because they're compressed is just that, an old tale.

You may be pushing it a little at that amount of drop on a stock strut/shock. You could try it and just look at the clearance from the top of the strut body. Try sliding an o-ring over the shaft of the strut before you button everything up, it will act as an indicator by sliding up the strut and letting you know how close it gets to the top. If I had to guess, I'd say you will replacing the struts. Have a look at Koni red/yellow, probably your best bet.
