Title: Toe Front/Rear
Post by: polilara on 02 February 2020, 16:17:39
Once again, front camber -1degree, 1minute how about toe in front/rear. Tomorrow is the day...

Front toe in 0.03, same both sides...

Rear toe whatever they can get as it adjusts with Camber, but ideally same side to side and thrust angle MUST UNDER ANY CIRCUMSTANCES BE ZERO. Accept nothing else.  :y

Thanks DG, what is the dimension Zero degree 0.3 minutes?? sorry, not clear... Rear side OK (understood).

FRONT TOE, NEGATIVE.  ::)

Yes, negative = toe in, but what does this mean? 0.03
Title: Re: Toe Front/Rear
Post by: Doctor Gollum on 02 February 2020, 17:07:05
-Zero degrees, three minutes ::)

Similarly camber is - 1 degree, ten minutes...

OK, clear, always so difficult...
And Thanks!

Still much better than me trying to translate it into Finnish ;) :y

Indeed, and it would be alot easier if not repeated 38 million times ;D

I just hope the damn drives well...

Finnish is easy:
Toe in = auraus
Toe out= haritus
Next time you know...

-Zero degrees, three minutes ::)

Similarly camber is - 1 degree, ten minutes...


when expressed as decimals, 3 minutes or 1 degree 10 minutes are NOT 0.03° or 1.10°!


1 minute is 0.0166666667°. Aproximately...........

Are these the WIM recommended settings or the factory settings?
What does the 'cross' figure in the camber and castor refer to?
Title: Re: Toe Front/Rear
Post by: Doctor Gollum on 03 February 2020, 15:57:13
They're not the Factory settings, which have been proven to cause excessive tyre wear.

I suspect the cross figures are the relative average across the car.

These were from the last time I had my plod estate set up, so poly front bushes and probably ATP wishbones, along with poly donuts and solid rear diff mounts, but otherwise factory Plod with working self levelling.

Car at this point had done 262k miles and had been rear ended three times and had two frontal impacts. Hence the caveat that they should be a reasonable target.

That said it drove like a missile and set up as above would see even tyre wear on all four tyres.

Too many things at the same time but this is how it is now, row by row, do I have to change something. I can go back there, he is my "friend" and not expensive at all.

Far too much front camber :o

You need to lose some front toe as well.

Rear is fine :y
Title: Re: Toe Front/Rear
Post by: polilara on 03 February 2020, 17:21:45
Nice to hear that rear is fine, good start. I try to convert the front Camber to degrees to understand how far 1 degree and 10 minutes is from actual value.
Title: Re: Toe Front/Rear
Post by: Doctor Gollum on 03 February 2020, 17:28:18
Take 20 from the last part of the camber number... Look at the link I posted earlier today... That way you can compare apples with apples ;)
Title: Re: Toe Front/Rear
Post by: polilara on 03 February 2020, 17:36:04
So 1 degree is 60 minutes which means that targeted value 1 degree + 10 minutes is 1,166 degrees. Actual value 1 degree 32 minutes is thus 1,533 degrees, more than 30% higher. So pretty much perhaps but is it worth readjusting?

Yes, ofcource not, there is a big difference, I check your link once again.
Title: Re: Toe Front/Rear
Post by: polilara on 04 February 2020, 15:02:19
Thanks DG for good enclosure. What is interesting is that:

"Nominal" Camber (front) in my paper is -1°55' while it is "your" maximum. As -1°10' is the recommendation I have to go to that direction, understood.

What is not understood is the plus or minus in Toe. According to Finnish papers Toe in is positive "+" and Toe out is negative "-" So, recommendation in "your" paper is Zero "0" and nominal in my paper is +0°05'. According to my understanding I have now Toe In as it is positive???

Title: Re: Toe Front/Rear
Post by: Doctor Gollum on 04 February 2020, 17:52:13
Being rear wheel drive, it should toe in at the front, (in exaggeration, picture the front wheels pointing to the front licence plate) yours is too much.

I might have been aiming for zero, but ideally no more than 03' each side.

Clear, next task to change radiator, which I already bought some moths ago. Come back with that in another topic...
