Hi all,
While on the subject of handling, I am getting ready to put new tires on my
Mk1. I was seeking any advice on specs for the front end alignment.
Currently, I have 175/70x13 tires on Cosmic 5.5 wheels and the I am told by
the previous owner the aligment is set as follows: Castor +3 - +4,
Camber -0.75-1.0, Toe 1/16th in.
I am considering 205/60x13 tires on the same wheels. The front suspension is
stock. Do I need to change my alignment specs and if so what should they be?
I saw Tom's reference to the CAT shop notes and the entry on alignment specs
for different tires. I looked but could not find it in the edition I have.
Thanks,
Jim Lindner
