i got a question..i know its not answering yours..but i was looking into H&R springs also. dont have to much knowledge about suspension, but i've read some some info that if you get springs you need to change shocks maybe. i have the same car as chen. sports suspension 19'' wheels. if i do decide to change springs H&R most likely sport do i need to do anything else? or can i do a straight swap? also the does drive stay the same or is it less smooth. thanks...sorry for going off topic..
