Technical Alighnment,camber,caster when changing to 155/65/13

[Big Q]

Hello everybody!


Is there enybody that have information about what to do, when changing from original 12" rims to 13" fittet with 155/65? I mean the alighnment, camber & caster.
I suspect, that if you ceep the original one, the car will perform otherwise than originally optaint from fiat´s owners manual.
I have a 1970f abarth replica, that i just got 4 weeks ago. It is not my first one. My first one was original fittet wheels.
The previus owner has fittet it whit other springs and dampers i can tell, but i don´t know if he did the alighnment part.
Thanks a lot.

I have 165/55/13 tyres on my '695' replica---I have kept 'castor angle' the same (9 deg. +/- 1 degree) as this is practically impossible to change--the spring mountings and the wishbone-to-body studs are set to this angle. Camber, if the car is lowered, (as mine is) set to 1/2 degree NEGATIVE--i.e. the wheels lean IN at the top (you often have to modify the wishbones to achieve this). Toe-in--set as per factory--0-2mm toe-in.
