i'm lost regarding some vibration issues I was having a couple weeks ago...wondering if anyone has any thoughts on what might be happening...
ferodo 2500 pads
dba crossdrilled/slotted rotors
stainless lines and motul fluid
stock wheels with dunlop star specs
work emotion's with goodyear eagle f1 all seasons
normally i drive around with the emotions and overall the car hasn't seen much "real" action since I did the brake upgrade and put on the star specs. I think I did one quick trip down mines road.
anyways, a couple weekends ago I did a trip with some friends driving pretty much all the windy roads from the south bay to mammoth.
on the first day, running the star specs, i noticed that after awhile, I had severe vibrations on braking from 60mph and higher. no vibrations at all during acceleration though and no vibrations from lower speeds.
pretty much lived with it during the trip, and just tried carrying more speed through corners rather than braking.
on the way home, I blew a tire and my gf drove my work emotions out to me. i switched rims and on the way home, now I have no vibration on braking but crazy vibration from 60mph and higher on acceleration and cruising.
I go and get the rims balanced and they tell me that they were out only by 0.25oz and that there is no way I would feel that but now there are no vibrations on acceleration, braking or cruising.
wtf is going on?
the only real tests I have left are to put the car in action to see if the braking vibration comes back and get the tire replaced and see if the other set of wheels was out of balance?
any ideas would be greatly appreciated.
