https://shoforum.com/threads/please-help-with-suspension-replacement.147579/ I made this post a few weeks ago, I ended up getting all my parts installed yesterday which included HR springs, lowering my SHO. I'm going to get tires and an alignment tomorrow but am hoping someone can help me with alignment recommendations. I asked GPT and got this reply:

2013 Ford Taurus SHO - Alignment Specification Sheet
Vehicle Configuration: AWD, Non-Performance Pack, Lowered ~1.5 inches (H&R or equivalent springs) VIN: 1FAHP2KT2DG145707
---
Factory Alignment Specifications (OEM Ride Height)
Parameter Front Rear
Camber -0.3° to -1.0° -0.8° to -1.8°
Caster 3.0° to 4.5° N/A
Toe (per side) 0.05° ± 0.10° 0.10° ± 0.10°
Total Toe 0.10° 0.20°
Thrust Angle N/A 0.00° ± 0.10°
---
Recommended Alignment Specifications (Lowered ~1.5")
Purpose: Improved tire wear and stability after lowering, balanced performance and longevity.
Parameter Front Rear
Camber -0.7° to -0.9° -1.1° to -1.3°
Caster 3.5° to 4.0° (fixed by strut geometry) N/A
Toe (per side) 0.00° to +0.02° +0.05° to +0.10°
Total Toe 0.00° to +0.04° +0.10° to +0.20°
Thrust Angle N/A 0.00° ± 0.05°

Technician Notes:
1. Ensure suspension is torqued with vehicle weight on the ground.
2. Verify front and rear ride height symmetry before alignment.
3. Inspect rear camber arms for bushing condition; replace if camber cannot be adjusted into spec.
4. Set front toe last; a small deviation toward toe-out (negative) can cause feathering.
5. For performance handling bias, use slightly more front negative camber (-1.0°) if tires are high-performance summer compounds.

Tire Rotation & Maintenance Tips
Rotate every 5,000–6,000 miles (cross pattern for AWD).
Check tread depth at inner/middle/outer edges after 1,000 miles to verify wear pattern.
Maintain tire pressure: Front 35 psi / Rear 33 psi (cold).

Summary: With the full suspension rebuild you completed, these settings will prevent excessive inner-edge wear from your 1.5” lowering while maintaining stable high-speed behavior and steering precision. Alignment shop should be instructed to prioritize equal camber left/right and zero or slightly positive total toe for best tire life.
Here’s your finished alignment spec sheet — optimized for print or sharing directly with your alignment shop. It includes both factory and lowered target values, plus technician notes and maintenance reminders.
You can view and edit it anytime here: “Sho Alignment Specs” (already created above).
Would you like me to also add torque specs (for control arms, struts, tie rods, etc.) on a second page so you can give the shop or reference them for future adjustments?"
Idk anything about tuning or performance tho I'm looking for extended tire life. Is this advice from GPT sound? Can antibody give me alternative suggestions if not?
Thanks a lot!
