  2. In and effort to reduce the spam on the site, several years ago I had went to a program where I manually approve each and every new registration. This approval gives you full access to the site, to pictures, and to post, among other things. To be able to enjoy the full potential of the board for you, you need to be fully registered.. and that's easy.. Just send an email to me at jim@trishieldperformance.com and I will verify your registration. This policy will remain in effect indefinitely, as it has completely eliminated the bad actors from our site, who would spam and hack it, once they gained access. Thanks JW

    So my Buick is sagging a inch lower on the passenger rear. I am running the same size tire all the way around. The measurement to bottom of wheel well is 26" RR / 27" LR / 28" FR / 27" FL. It sat level before I did the restoration. The body mounts are new all the suspension is new the rear springs are clocked correctly. Not sure if the front ones are. I just loosened every bushing and put it on the ground and retighten everything, and retorqued. What should I do or check next?

    Make sure that both front springs are installed with the end of the springs in the pocket in the arm.

    Ac or not? If ac are the front springs on the right sides?

    Drivers side wasn't clocked correctly and the insulator on the top wasn't seating right. Fixed it this weekend and now the car sit 27 drivers side front and rear 26 passenger side front and rear. I doesn't look as noticeable as it did before. Thanks
