Red, buy Laurent's Moregos after he has changed them for the TTs.
Laurent, it depends on your car's momentary ''behaviour'' and your personal preferences.
I'd suggest 0°20' toe in front and zero toe rear, but you'd better tell me what you want
from the car and if you have a data sheet with the actual geo post it here before.
If you ever need adjustment and plan a trip to the Ring join Raeder. A bit expensive though
(regular 200,-- € incl. corner weights, I had a special price), but worth it imo.
