The Arospeed's are perfectly fine. In fact, i knew somebody with sprints, and they were retty bouncy. I didn't like them. They are all basically the same ride though. Arospeed springs and strut bars are just as good as most other brands. A strut bar is just a just a strut bar. There's absolutely no difference between the Stillen and an Arospeed bar. Except the way it looks. Same with springs vs some other brand. Arospeed actually has good springs and i highly recommend them to anyone who wants a 2" drop.
