It is definitely the roads/highways in my area because there are certain spots where it's bad but as soon as I touch repaved the car tracks straight as an arrow. Asking if there are any adjustments that can be made to help reduce the tracking.

Getting rid of my wide & sticky tires is not an option.

Current susp mods:
FRPP springs
Tokico Dspecs
BMR swaybars
UCA & LCA's, adj panhard w/brace

I don't have the specs of my alignment in front of me.


Will a bumpsteer kit or X5 balljoints have any affect?

 

Last specs on the alignment

Left & Right individual
Camber -1.4 degrees
Caster 7.5 degrees
Toe .11 degrees
SAI 17.3left/16.0 right

Total front
Cross camber 0 degrees
Cross caster 0 degrees
Cross SAI 1.3 degrees
Total toe .22 degrees

also forgot to mention above, I have LCA reloc brackets as well.

 

Car is tucked away for the winter, but still curious on this.

 

I don't think theres any thing you can do about it. Don't let go of the steering wheel

 

I have the same problem with mine running 275/40-18 all the way around. I have had my camber adjusted from -1.2 to -1.8. It seems to have limited the tracking a little, but now I'm worried about wearing out the inside of my tires. Usually everything is fine. But as soon as I hit some of the roads around here I have to put both hands on the wheel. Just the nature of the beast.

 

Apples and oranges, but my truck with 10.5 wide tires all around is much better/nonexistent tracking on the same roads.. thats why I'm wondering if an adjustment/part swap would help.

 

from what I understand, that is what the bumpsteer kit is supposed to help fix. You might want to call someone like Gus at Steeda to confirm if that is indeed the true result of using those parts.

 

It's all in the size of the tires you are running.

 

Toe in sounds a little light. I'd try 0.13 deg to 0.20 deg per side. It it works, then monitor wear. This amount works good on early Mustangs. I would run half as much camber too unless the car spends more time on the track than the street.

High performance tires tend to be twitchy, particularly the lower the aspect ratio because there is less flex.

 

the toe measurements should read pos or neg(+11 or -11) right? like how you posted about your camber and caster measurments. if its +11 then i believe its toed to far in and -11 i think would be toed too far out, right? are you sure it read .11?

 

Positive toe is in and what he is indicating is 0.11 degrees per side w/o a minus sign. That is about 0.100" total toe in on at 26" dia. tire. Back in the days, toe settings was always described in inches, and a good rule of thumb performance setting for a Mustang was 1/8" to 3/16" toe in.

If it was toe out, I think he would have very noticeable rapid turn in rates and very unstable (as opposed to tracking issue) trying to go straignt ahead.
