Hi
I just had my car aligned last weekend with the following specs
Front left -1.56 with .14 toe out
Front right -2.06 with .13 toe out
Rear left -1.87 with .19 toe out
Rear right -2.02 with .23 toe out
Problem: my car wonders left and right and then stabilize when I accelerate on the highway. I the control arm bushings were done last year. I have vorshlag plates with rss H&R coilover.
I do track my car. I did a search with people running 0 toe in from and a slight toe in at the rear.
Anyone care to provide their input?
Thanks

 

A bit of toe-out all around would be good for autoX, but 0 toe front and 0 to slight toe-in
rear would be best for stability at higher speeds. That's what I run on mine, which is also
my daily drive. The camber you cite looks ok for street, although it would be nice if the
fronts would match just a little closer.

 

Doesn't mushroomed strut towers contribute to drifting problems?

 

Would there be a way to fix it if that is the problem?
I will check tomorrow. My the way does the toe in on the mini increase if I were to increase the negative camber in the front during track day? I have one next weekend.
Thanks

 

toe-out causes directional instability, especially rear toe-out

good for the track, bad for the street

Yes, increasing negative camber in the front using a camber plate pulls the top strut mount inward,
and since the back of the hub is attached to the tie rod, the front of the tire angles toward
the inside, causing more toe-in.
How much per degree of camber? Measure the toe in before and after changing the camber with a
tape measure and a friend, or a toe-in bar, or a formal alignment at a shop, and please report back
here so everyone knows!

 

Fast or slow acceleration? When I floor it you get a good amount of that, and im pretty sure its torque steer

 

Torque steer will pull one way with hard acceleration, and the other way with
quickly letting off the pedal at high-ish rpms.

 

I do not accelerate to the point where my tires are not gripping enough. I just do medium acceleration and it does this.
I booked an appointment for Monday morning. I am Wondering if I should pay for a garage that handles race cars. They charge 125 plus tax for an alignment which will be right under $140. They will inspect my car for free before the track day.

 

Sorry for the hiatus. I have been busy with work.
I finally went to a garage which handles mostly track cars.
The alignment was off -.5 on one side.
The cambers are presently -2.1 left and right and 1/16 toe out left and right
Oh yeah guy s regarding adding camber at the track is not a good idea since adding camber will reduce the toe angle by about -3/16 from what I saw.
The car is driving fine now.
I bought the New Rival tires for track day. Lets see how they hold up
Cheers

 

Adding camber for the track is a good idea, but only if you plan on changing the toe in settings when you change the camber. Toe out causes the wander... Glad you got it straightened out (no pun intended!)...

 

I am going dial in some negative toe at the back and maybe add .5 positive camber at the back. He front is stable right now but under hard braking the rear is a bit twitchy with the current rear toe setting.
I only tried this once on the street to test it out. I want to have the alignment dialed in before I hit up circuit mont tremblant in July. I already missed today's track day.
On the subject if handling: which model will handle better r53 vs r56 on the track with similar handling hardware (sway bar, camber plates, bushings, suspension)
I am strictly talking about handling. Please factor out the HP and power delivery since we are always in high rpm most of the time. Anyone want to chime in on this? I am just wondering
