I figured some of you would be very interested in this...
I found some amazing deals on discontinued Noltec castor/camber plates, on Ebay. I bought two sets, one for me, one for my brother. I bought them on Wednesday and already got them today from California.
There are two options.
The street use a pillow ball bearing with a urethane cushion. They are only $100 a set.
The clubsport, are a solidly mounted pillow ball bearings and have slightly more adjustability. They also cost more, at $150 a set.
