Courtesy of Phat VW from the Vortex. Thought It would Make a nice topic here as well.
Thanks to the input from manufacturers and vwvortex users, we now have a catalog of eight different camber plate options and two different upgraded spindle arrangements. Don't give up on the MkIV platform just yet!
Background:The MkIV front suspension allows toe adjustments only. Minor camber adjustments can be made via shifting the subframe and loosening & re-torquing certain suspension bolts. But from a practical standpoint, camber & caster are fixed. For high-performance driving, especially autocross & track driving, a certain amount of negative camber is required to keep tire wear in check and help maintain cornering grip. Excessive negative camber can reduce grip in straight line and increase tire wear, so more than a degree or two is not recommended for street use. Camber plates allow the driver to customize the camber angle to optimize performance vs tire wear.
