Dual Purpose Geo Settings
Discussion
Hi,
I asked this on the CaymanOC but thought I'd ask here as well. Also before I got torn to pieces, I am not a driving god but simply a casual track day enthusiast...
I'm looking for thoughts on a dual purpose road and track alignment for my Cayman (987).
The car is full polybushed (with adjustable front arms) on Bilstein B8s and Cayman R springs. I currently have it set to -2.25 (2 degrees 15 minutes) front and - 1.6 rear with 2 minutes of toe in on the front and 5 minutes per side on the rear.
This alignment works well on track (I appear to be using all of the camber on the front) but it is a bit too aggressive for the roads round me which are badly potholed and grooved. It's not unmanageable or dangerous feeling but you do need to be concentrating.
My old boxster ran close to a standard alignment and was more enjoyable on the same roads despite being less capable on track.
I'm thinking of dialing down the front camber to -2 or maybe - 1.8, running just a little toe in and then keeping the rear the same as it is currently. Track tyre wear will be worse but hopefully road manners will improve.
What are other people running and what is the compromise between road manners and track tyre wear like?
Oh and this isn't my main car so doesn't tend to get used on long motorway journeys/commutes etc
