Car doesn't drive straight
Hi All,
I have a 1989 coupe. I've noticed that up to 30mph my car drive very straight, I can take my hand off the wheel and it goes straight. Once I start getting any higher in speed I notice the car starts to slowly move to the left or right. I guessing because of the way the road is leaning...
Anyway.. I've heard of cars that seem to follow every bump in the road and wanted to know if anyone else car does this.
I checked and my front tires are aligned the same distance apart front and back of the tire.

dont get an alignment yet you will waste $$
your problem most likely is the rear toe rods. Get under the car and you will see the bracket bolted to the diff that has 2 bars going to each knuckle. check all the bolts. if they are all tight check for play by having someone push the car side to side or tug onthe rods. it could be the bushings have worn out if theyre still stock. there are decent cheap replacements available at ecklers midamerica etc and vbp.
Heres a link for heavy duty ones from vbp. they have $130 dollar ones as well.

More than likely as you described it the rear wheels are changing directions as the speeds increase the tires are following the road grooves (the toe is changing constantly)
If the rear is fine perhaps your front end components have play in them. Tie rods or ball joints can cause this.
