Here's what I did. Using a 6 ft long level and linolium floor tiles from Home depot, I was able to make a perfectly level surface. Drove the car up on the tiles and adjusted the camber (1.2 front and rear). Front camber plates are exactly on the same marks left and right too. Used strings, and a 7ft long bar, ruler, etc. to measure toe. I don't think the string idea worked correctly. Long story short, basically front and rear toe is 0. Drive the car on a relatively flat road let go of the steering wheel and the steering wheel is straight but drifts slowly to the right, just a hair. Only thing I did differently is change to differnet coilovers and the height is same as with the old coilovers.

Is the trust angle off, meaning the rear wheels are not pointing parallel to the front. Caster, though there is no adjustment and didn't have this problem before. I'd like to figure this out myself so I know how to do this in the future at the track (so please don't tell me to go to your favorite alignment shop). Can anyone help?

 

On most roads in the US with toe at 0 and thrust angle at 0 your car should drift slightly to the right. Almost every road is crowned for drainage. My car was professionally aligned to 0 toe and 0 thrust angle and will slowly drift right on most roads.

Some roads are crowned to the left and the car still pulls to the right.
