A set of Turner race camber plates for E9x M3s, has caster adjustability. Was going to be part of my front suspension overhaul, but turned out I didn't need new camber plates; these were never installed.
This set was ordered with spacers that fit 14mm shock pins, with spring hats for 2.5 inch ID springs. Turner sells a variety of other spring hat versions at modest prices that'll fit different spring and shock pin sizes.
Around Anaheim Hills 92807, $300 local pick up, can ship at buyer's expense. Please drop pm if interested
Here is link to what I believe is the configuration of my kit; Turner's description states compatibility with springs having 60mm/2.25"/2.5" internal diameter
