those struts are just fine, but you might not even notice that drop. I have the S tech and recommend them.

Cheaper too.
And if you're worried about the ride, don't be, they ride great and I drive on some really bad roads.
Edit: You should get new strut boots too. Maybe even front mounts, don't worry about rear mounts; there isn't any rubber to deteriorate in them.
Edit x2: Some companies ship the GR2s and S techs as a combo because they go so well together.

Don't buy from their though; nothing wrong with enjuku besides that they jacked the price. When I bought this combo from them it was around 350.
