Starting to shake around 55-60mph is typical symptoms of one of the front wheels being out of balance.

Take it in for a tire balance/rotation. Should fix your problem right up .

Doubtful.

The motor mounts theory would be sound if it was when he got on and off the gas hard and such - not when he's just cruising at a relatively constant speed or slow acceleration above 55-60mph.

EDIT:
I haven't had as many motor mounts problems as most people *shrugs* but generally a motor mount doesn't make the engine shake - and if it did it would transfer it through the front frame rails and into the sub-frame where you'd feel it throughout the entire car, not just in the steering wheel - it feels more like your engine hit your firewall when you stabbed the gas too hard (and sometimes that's actually what happens, especially with the bigger swaps if you have too light-weight mounts). A shaky steering wheel above 55-60mph is a typical front wheel being out of balance symptom. Anybody mechanic or "car guy" that you know will tell you the same thing.

 

THANKS FOR THE HELP FELLAS!!!!!!!

 

it could be that the wheels are imbalanced, brake rotor being warped, or your lug nuts arent torqued properly.

 

can be numerous things...

wheels are un-balanced
rack n' pinion is going bad
calipers can be warped

check those first, my friends 240 did the same thing once he got to 45 and it was the rack.

 

or this
tire receives its speed rating by the U.S. Government through meeting minimum standards for reaching and sustaining a specified speed. What does that mean to you? Well, in general, a higher speed rating will result in better car handling.
Two important notes when considering speed rating:
• We do not recommend downgrading the speed rating of your tires. This may result in poor handling and unpredictable steering. However, if you want better cornering response, there is no problem installing a higher speed rated tire on your vehicle.

• Never mix and match tires with different speed ratings on your vehicle. This will cause serious problems with the handling of your vehicle.

Below is a list of speed ratings along with the corresponding speeds they represent. Remember, the speeds are test speeds, not recommended speeds.



Q- Up to 100mph
R- Up to 106mph
S- Up to 112mph
T- Up to 118mph U- Up to 124mph
H- Up to 130mph
V- Up to 149mph W- Up to 168mph
Y- Up to 186mph
Z- 149mph and over
