If it makes you feel any better my car shakes... Starts at like 10mph slightly and by like 70mph is unbearable... I guess it keeps me from speeding...
It does go away a little above 80mph though...
We can work on my car... I'm working on an elongated, polished TB right now... I have a 3L tb but im not sure if I can make that one work.
Also, im thinking about ordering up the LED's to finish up my interior...
EDIT since pics are up:
Bill, it looks like that ring may be part of the brake rotor. Anyways, i'd pull it off... If you can't get it off, maybe try unbolting the brake caliper and pulling off the rotor.
Oh yea, hit all if your bolts with WD-40 or PB blaster or some kind of penetrating oil, so when we do suspension things are nice and freed up... Those are gonna be even more of a pain to get off than mine were...
