I have the eccentric SPL bushings on mine. Then you can adjust castor for your liking. Quite a noticeable difference. Better road feel as they are solid. Better steering input but also more sensitivity on uneven roads as the car moves a little more and requires a bit more correction. The downside is more road noise. If you want to be able to increase Castor and not go solid bushings you can use a Powerflex eccentric polyurethane bushing kit. That increases castor 0,5 degrees. It also ha s a higher Shore number so increases stability too. You can't increase Castor too much if you use stock or slightly bigger tires as it will rub at the front of the bumper/inner fender.
