I have had it up to 90 mph once without realizing it as I was following
traffic on 95, barely pressing the gas pedal.  But I do not drive that fast
normally.  Plus I have had a problem with the front tires throwing the
weights off after I get them balanced.

Without wheel weights, past 70 mph the front starts shaking, so until I get
my 15" rims and tires online, I do not go past 70~75.  I have 15" rims on
order, hopefully they will get here today. I plan to run some nice tires soon
(I still am deciding on tires).
