Question Front End

I just climbed under my 01-756 SC - thought I heard a rattle or clunk last night in the front end! Everything looks tight(?) - Sway bar bushings torn apart between upper and lower. I was shocked to see really bad wear on the inner shoulders at both front tires - about 1 inch wide - cords showing. Tires need replacing - front end alignment. I had already noticed aggressive wear on out side shoulders?? What gives - does not look that bad sitting - could expect the outer shoulders - also does not look like much adjustment available. Any advice / experience would be great.
I work for Michelin - will get some Pilot Sport's. 265/35ZR18 for the front and 295/35ZR18 for the back -correct? I have the 10" rear wheels and big brake upgrade.

I haven't experienced the issue with the sway bar bushings on any of mine so I can't help with that. However, I have added caster/camber plates to both of mine and of course had them re-aligned. This took care of the wear issues. However, my S331 experienced the same issue with the tires showing cords on the indside by 15k. Just seems to be the way Saleen sets them up.

Those are the "correct" tire sizes for our cars with the 10" wheel upgrade. I will probably go one size wider as the wheels seem to be wider than the tires.

Default Thanks.

Thanks for the feedback and suggestions. Where did you get the caster/camber plates?
Does anyone know the setup specs for the alignment?

Default Alignment

Hope this Helps....
Camber: The tilt of the tire relative to vertical. If the top of the tire leans inward (towards the engine) the car has Negative-Camber. If it leans outward, that is Positive-Camber.
- Negative-Camber gives the car more cornering grip and improves steering response.
- A car without enough negative-camber will understeer and wear the tread off of the outside-corner of the front tire.
- Too much Negative-Camber will wear the tread off of the inside corner of the tire
Camber should be adjusted to suit the use of the car
Type of Driving Camber*
Drag racing-no street use -.2° to -.5°
General street use -.7° to -1.1°
Aggressive street handling -1.2° to -1.5°
Road race / Autocross -1.8° to -2.5°
Specifications are for Ford Mustang only
Observe tire wear (street) or tire temperature (race) and adjust camber as necessary:
- More Negative-Camber (-2.0º) gives better cornering grip and more wear on the inside edge of the tire.
- Less Negative-Camber (-0.5º) gives less cornering grip and more wear on the outside edge of the tire.
Caster: is the how far the contact patch of the tire follows behind the imaginary line where the steering axis of the wheel intersects the ground. (Think of the front wheel of a shopping cart, where the wheel follows behind the steering axis.)
More Caster gives you straighter highway tracking with less "wander" and better self centering steering feel. It also makes the tires lean into the corner when turned, in effect producing more negative camber when the wheels are turned. This allows you to use less aggressive Negative-Camber settings, thereby improving the tire contact patch for better braking and reduced tire wear when the wheels are straight.
It is theoretically possible to have too much Caster, but to do so in a Mustang would require extensive sheet metal modifications. So for our purposes, we recommend the Maximum Positive Caster that can be achieved with our Caster/Camber plates. To get the most caster, push the top of the struts as far towards the rear of the car as possible when setting the alignment.
Note that the amount of Caster that can be attained varies with the year of the vehicle.
Year of car 1986-89 1990-93 1994 & up
Factory Specification (Caster is not adjustable without C/C plates) 1.27° 1.75° 3.6°
Typical Maximum Caster with Steeda C/C Plates 3.1° 3.4° 5.0° to 6.0°

Toe Settings. Toe-in or Toe-out describes the alignment of the front wheels relative to each other the same way you would describe your feet. Toe-in means they are closer together at the front than the rear.
We recommend factory Ford toe settings for all situations except track-only racing, where toe may be adjusted by the crew chief as needed. Factory toe settings are given in degrees. When setting the alignment with a tape measure (the way we do it at the racetrack) set toe to 3/32" total Toe-in.

I sourced both sets from Saleen. The first set I purcahsed was for my 00 about 5 years ago. Those were HPM's with "Saleen" machined" into them. I bought a set earlier this year for my 95 and they were standard Hotchkis.

Fantastic information, thanks! I have saved that for future reference - I think it should be a sticky somewhere.
