Suspensions and stearing setups

[Abe]

I fint the card whit my current setup:

Camber L/R: -1'16/-1'14
Castor L/R: 3'38/ 3'50
Toe L/R: 0'60/ 0'60

But I change the cambers, and go to -1,50/ -2'

I still vote for tires

Abe the offer stands, whenever you want drop buy and we'll swap wheels and you can see what better rubber does. It will only cost you a drive over here and back

Abe,

Ah I missed that bit, thought you were closer, mixing up forum members lol

Netherlands so yeah, that it a fair amount of driving, you'll be cheaper off just buying the tires...

new set up:

Camber: -2º15'
Caster: 3º 55' (edit)
Toe: 0

the cars works better, more neutral... but I cant prove it good, because the tires rub into the rear panel when I turn.

and they have a lot of problems to put the castor, the tension rood works at inverse? when they make the tensión more long, the caster is more¡?¿?¿? i can´t explained this....

If i have more caster the front whell goes to the front bumper, no? my front wheels goes to the door and the computer said that I have more castor

Postive castor is what u want ie moving your wheel closer to the front bumper!!!

turn would absoutly suck with that setup

ahhhh Sorry.... no no

Caster: 3º55' not -3º55'

Sorry very much but i write bad in the first post..... but this number of caster is bad, i think they put me arround 2º of caster and the tyre rub in the fender...tomorrow I go to change it and put a real 3º55' of caster

Your alignment settings seem very conservative..I ran 2.0deg of camber and 4.5deg of caster on my miata. Those have double wishbones, so you should be way more towards the extreme.

Try 3 degrees of static camber or more, 6 or 7 degrees is perfectly normal for a mcPherson strut race-car..so half that would be a good start for a road car.

Dial in as much caster as you can get. 5 or 6 degrees is fine, whatever the adjustment range on the rods will give you without rubbing issues. Very nice for feel.

Finally zero toe is theoretically fine. Its the best setting for tire wear. Do you have poly bushings in your car? If not then you can dial in a couple of mm toe-in without problems. The weak rubbers allow the suspension to deflect a bit while driving, causing toe-out. A bit of toe in will correct this. The stiffer the bushings and toe-controll rods, the less of toe-in you'll need.

Hope this helps, good luck.

The end...

Yesterday I saw that whit less Caster my car can turn whit more response, the transsitions are fast... and I like it... and today I go to the minimun caster without rub in my fender...

The problem of understeer in my car was the toe, I had positive TOE and the car understeer so much... Now I have this setup:

Camber: -2º 15'
Caster: 3º 20'
TOE: -0º 01'

Now my car understeer less with gas than before whitout gas , I cant prove it all, because the road not is good... but I have very good impresion at this moments...

Regards and thank you very much for your help
