Ford Recommended Alignment Sheet - Typo

[wildcatgoal]

Alright, I'm going to have to try "toe out" for a track alignment next. Seems to be all the rage these days.

0 toe in the rear, "upgraded" integral links because they have less axial play than stock? Man, can I hire you to set up my car?? :lol:

:lol: Oh man, I didn't see this one yesterday. Help me (us) understand why 0 tow in the rear is bad? What research have you done and applied into what S550 (non-GT4) race cars/track cars are doing as it pertains to alignments, aftermarket parts, driving style, and track? Has any S550 race/time trial/race car driver shared with you his alignments specs? Have you been on track with your S550 at all and/or with 4 different alignment approaches (at $180 a pop) like I have to experiment with said advice? None of the above makes me an expert, just a participant in this community.

I'm looking forward to all the knowledge a former BMW owner can contribute to this forum articulated, of course, eloquently and without fault. Thanks!

I'm not sure what you want to "tow", but as far as running 0 rear "toe", (taken from the "car is unstable under braking" thread):

The S550s rear toe link is ahead of the wheel centerline and at stock ride height, the arms are almost parallel with the ground and just slightly angled downward from the chassis to the hub, this means the car toes-in under droop and barely toes-out initially before toeing-in under compression. Due to the angle of the arm, I wouldn't be surprised if there was no measured initial toe-out under compression.

Depending on how much *an S550 is lowered when running* 0 rear static toe, it's possible the car is toeing-out under droop travel under braking. Even if (the car isnt) lowered that far, he will still be in the arc of the toe link curve to not be getting toe-in under braking anywhere near as early in the droop travel if at all.

Again, his "problem" of a lack of rear stability under braking is due to a lack of stabilizing rear toe-in.


But you're free to buy whatever parts you want and run whatever alignment you want. As long as you're happy, unless you're looking to improve on your setup and go faster.

I thought front toe in was odd for the track alignment. It should be out like the regular GT350. Why it is in for the R makes no sense.

Not necessarily. The front calls for essentially zero toe. Zero and toe-IN at the front sharpens the initial steering response, improving turn-in since the outer (loaded) tire is already turning into the direction of the turn. Toe-out requires the outer loaded tire to waste steering lock to be steering straight before THEN turning into a corner. This is why toe-out actually slows down and dumbs down the on-center feel and initial turn in, which is contradictory to most people's understanding of toe.

:frusty:

I'd love to have me a toe vehicle. I mean tow.

I have not a single complaint about instability under heavy braking myself. Ever since, hmmmm, I went with 0 static toe in the back. Go figure. Only lowered .75" on my car, but pretty high rate spring. Must be those vertical links... has to be.

I thought the same but it is "in"

So....what truly is Fords 'Recommended' track setting?

so are you recommending front toe out or toe in ?

this is really confusing........

 

[snaproll]

At less than a tenth it doesn’t make any difference either way but out is better for turn in, no doubt.

Depends on what you want the car to do. Start with OEM settings and go from there.

At less than a tenth it doesn’t make any difference either way.

Not a big difference.

but out is better for turn in, no doubt.

Not really.

Not really.

Ok, I’ll bite, only a real racer offers this with authority. Billy? Dean? Please stand up. :ford:
