Ya, there are an even 4. Cut right in the middle of the first 2 and the last 2.

Cutting the bump stops won't lower your ride at all. The reason you're cutting the stops is because you're shortening the travel of the strut and if you have the entire bump stop intact, there's a good chance you'll hit it when you go over a bump. By cutting it, you're giving yourself more travel on the strut, that's all.

Hope it helps
