Inner tire wear issue

[RocketGuy3]

I believe it's a well known thing that the inner side of the front tires on our Mach 1s wear out quickly/unevenly, but the only suggestion I've heard is to align the front tires with more toe in. I tried such an alignment, but the tech at the tire shop (Discount Tire, which may be my problem. as they're pretty hit and miss.. the guy didn't seem like the most experienced) told me that anymore toe in would cause the steering's neutral position to be off center, and the car wouldn't naturally drive straight.

What I'm wondering are are there any other potential solutions for the tire wear on this car?

I've had similar issues on a previous RWD touring car where all the toe adjustments in the world didn't seem to be sufficient. But what ultimately fixed it was stiffer LCA bushings. The reasoning being that stiffer bushings limited the amount of wheel deflection around the kingpin under both braking and acceleration. Both braking and accelerating rotates the tires around the kingpin giving more toe out than desired. It has the added bonus of slightly more responsive steering and turn-in.

Other info:
- I don't have the handling pack
- Bone stock
- 99% "spirited" street driving, but I have done one fairly aggressive track day

My most recent alignment:

Thanks for any suggestions.

My understanding is that such wear occurs because these cars are set up for track uses. If the car will never be tracked, the alignment can be adjusted, but then it won't perform well for high performance driving.

This, I was told.

You have enough front toe in. IDK what he’s talking about with more toe causing it to not steer straight, but he’s right you dont need more thatn that.
