My car wants to turn slightly to the left if I let go of the steering wheel.And sometimes at high speeds the steering wheel will shake a little bit.I'm concerned cause I do some drag racing and want to feel confident when I'm going 100+ down the quarter mile.Could it be my steering linkage.

 

I would say you are due for an alignment check.

 

Yup, time for an alignment and a balance should take care of the wheel shake at high speeds.
