Intrax are to low and to soft, especialy if you are sagging because of all that stereo equipment, you will just be riding on the bumpstops and it will feel and handle like shit. I will be putting on my B&G springs tonight so I will have pictures and a short write up tomarrow, maybe that will help.
B&G? Yeah, lemme know. Right now its either Eibach or B&G, whichever is progressive enough to hold 300lbs in the rear and not sag. lol. ex: get 3 people to sit in your trunk and let me know how it sags
