I didnt have the car very long before suspension mods were installed, I want to say the car drove straight as stock. Since then, solutions to fix the pull to right include the below with no solution. I would really like to get this fixed.

1st Attempt - Ford Dealership "A"
Spent $225, car was there for three days, no spec sheet returned, cant solve pull to the right and car drives with rear-view mirror shaking considerably. Im working to get the spec sheet retrieved.

2nd Attempt - Independent Racing Shop
Spent $725, car was there for a week. Conclusion, nothing wrong with the suspension components, alignment is correct, car still pulls right. Hypothesis, steering rack sensors are not properly calculating torque which is creating a false steering neutral at some degrees to the right. Neutral position is a calculation, the computer is mis-calculating, but doesnt know it. NO CODES THROWN.

3rd Attempt - My buddy at the Ford Dealership "B"
Spent $0, Connects the car to IDS, recalibrates steering to 0.0, goes on a test drive...no more pull. Car cyles on/off, computer recalibrates steering, car pulls...or so goes the theory. Ticket is opened with Ford Technical service, response:

"The steering wheel angle may not read exactly zero degrees, and this finding in itself is very likely to be a normal condition. The ABS module recalibrates the steering angle position on every ignition key cycle during its system initialization. If there was a fault in steering angle, there would be DTCs set in either the ABS module or the PSCM or both, and there would also be warning indicators or messages present reflecting those codes. It is recommended to diagnose the vehicle pull condition."

4th Attempt - Ford Dealership "C"
Spent $100, Spec Sheet Attached, (NOTE:Alignment performed due to slight accident to rear driver wheel, knocked the Toe out of spec) Hence the before Specs are from the 3rd Attempt above, car drives happiest with these specs, still pulls right. Currently car feels like its twisting under medium to heavy acceleration, broke free and tried to come around CCW on a 2-3 push, and of course still pulls right.

Specs look fine. Could be a radial tire pull. Try swapping front to rear and see if that makes a difference.

I had a similar issue where I though it was radial pull, swapped tires and same issue - turned out to be a very fine tuning of the tire pressure across all tires.

Verify the cold pressures are within 0.5 PSI (or less) of eachother.

I kid you not, when I say this fixed my issue.

This solved this issue for me. I swapped the fronts side to side.
