Please try a search. There are many threads on this topic.

Eibach springs come with instructions that tell you how to much to cut. Pro-kits, for instance, specifically say NOT to cut the stops. If you don't have instructions, call Eibach. Don't cut anything without knowing exactly.

For the future.. please use the search.. I happen to have my Sportlines sitting 2 feet away from me, so I can tell you right now.
But, in general, there are threads made every week about this, so it's really not hard to find out.

Sportlines advise to remove 30mm off the bottom of the fronts, and 13mm off the bottom of the backs.

Wow. That is one of the most irresponsible posts I've seen a long time. Advising somebody to just cut away after we gave them the exact information they needed. Way to go.

This topic is getting beat up a lot lately. So this will be my next sticky topic.

Had my sportlines for almost 2 years now and never cut the bumpstops. You don't need to cut them.

Thats a much better post. But after reading it, it also says how cutting the stop needs to be very specific. And the Miata setup is significantly different from the Cobalt.

No offense intended.. but for the safety of other peoples property, I hope no one ever listens to your advice...
Telling someone to cut off as much as they want from the bump stops is like saying they don't have a use in the first place. If they didn't have a use, they would have never been made at all. If you cut off to much, you risk bottoming out your shocks, and that's never a good thing. No sense in having to buy new shocks before you normally would have to.
