You should be fine. GF aren't made to slam the car. More on the handling... It doesn't drop over an inch too.
Tanabe USA Inc. - GF210 Grip Feeling Springs
I don't know how it would tear up your axles and what not though... that's pretty BS. Stock struts are going to die some day... putting springs is like smoking it'll kill you eventually/it'll shorten the life of your struts. I've had and used springs in the past years.. and struts are still good even after 50k+ miles.
You're good withte GF!! Get them and tell us how you like them!
