Alignment specs anyone?

[Steampunk]

Sorry to resurrect an old post but my 2 cents:
I found these on the Miata.net forum. The guy knows what he is doing as he goes into great detail about spending a whole day or so, changing one parameter at a time. Below are his recommendations for \"spirited\" to \"slightly aggressive\" road driving;

Here are my 1994 Miata's current alignment specs:
Rear
Toe: 1/32 inch (0°4.5' or 0.075°) IN per side
Camber: -1.75 degrees

Front
Camber: -1.2 degrees
Caster: 5.0 degrees
Toe: 1/32 inch IN per side


I had Fulcrum in Brisbane do this for me but with -1.70 and -1.1 Rear/Front camber. Works a treat with stock suspension bits.
There was a tangible difference ... but that is only cause the alignment pre realignment was WAY off on 3 out of 4 corners

I have my car set as follows:

Front:
Toe : zero
Camber : -0.5 degrees
Caster : Max possible (usually around 5)

Rear:
Camber : -1.0 degrees
Toe : Zero (Many people like to run some toe in to avoid oversteer but I've never had a problem)

Those settings will be fine for street driving, and occasional track use. I set my fastest laps with these settings so they can't be that bad...

Front:
1.3 degree negative camber(max)
6 degree castor(max)
0 Toe

Rear
2.5 degrees neg camber(Max)
0 Toe

This is barely lowered on standard bushes. Track settings but I guess we'll see how it go next trackday....

[StanTheMan]

why would you go toe in on the fronts ?

[Hellmun]

If it was primarily a highway car it'd probaly make it track straighter.... always considered toe a preference thing rather than something you can tune for grip.

Doesn't toe affect steering response? and toe \"in\" means the front half of the wheel/tyre points inward?
I was just taking advice from those who know better, and from what I read, toeing in on the front quickens and eases steering, cause the example scenario is say you are turning left, thus it loads up the right side, thus right-front wheel doing more work than left-front, and if the right-front wheel is already pointed inwards, ie \"toe in\", then you steer into the corner quicker.
Yes? No?

No. Toe out on the front improves the turn in but has the draw back of making the car "tramline". Toe in removes this "dartiness" making the car easier to drive.

There is a heap of information on alignments in the Archive Section. Have a look there.

Ahhssoo

I found Lanny,s alignment extremely lethargic,.
but it suits the American freeways

[Steampunk]

Ahhssoo ... the specs I found are biased toward highway cruising? Hmmm ... this is good .... cause next time I get her aligned, I'll change the settings to those suggested here and thus she'll turn even better! tre bien!

I run a fair bit of toe in on the front because I do a lot of high speed country driving. I found with 0 toe the car is too darty and very tiring to drive long distances like that. If most of my driving was tight twisty roads I would run less toe and enjoy the faster turn in.
