Lowering Springs Poll: Eibach, H&R, Tien, or other?

[hyd003]

Eibach and H&R are on Tire Rack right now for 232/234. I have seen Tien and Eibach mentioned on here a lot, haven't heard anything about H&R. I'm planning to do something next weekend and I wanted to get some opinions on the pros and cons side by side if anybody has experience with these models.

Thanks!

I plan on going with an eibach pro-kit. I've had this set up on another car and it was really nice.
