It's a fight for the best steering you can without causing front driveline vibrations.
Anything over 4.5 degrees will give you nice steering, going to high will cause vibs
Thanks for the tip. Does this recommendation apply to stock shafts or aftermarket double cardoons?
this is for aftermarket shafts. a factory shaft will allow you to get a bit more positive caster but, doing so will cause the cv boot and joint to fail prematurely. more would be better but, about +4° is where you want to be.
Thanks Eddie. I was running around 6.5 with prior 3" lift. Switched to the Evo Bolt-on coilovers and running just over 4" now and noticed a slight pick up in vibes. Had both shafts re-balanced and ujoints serviced and still noticed vibes, so I'm going to try dialing castor to between 4-5.
are you sure the vibes are coming from the drive shaft? the more positive caster you add, the more you should feel vibes. if anything, you will need to go less.
