My 2003 Jetta 1.8t tiptronic has 65000 mi I'm on H&R sports with oem struts, 18" BBS RC's and have 15mm H&R hubcentric spacers on the rear, and for about two weeks now my car vibrates at 35 mph and up. As soon as I let off the gas it disappears. I have searched the other mk4 forum and there are guys experiencing the same problems and replaced their whole suspension and drivetrain it seems like, but never came to a solution or atleast never posted that they fixed it. The dealership ofcourse wants $1400 to replace back to stock absolutely not. Please help me I don't know where to go and what to do.
