I think the current rules work very well. Adjustable camber, stock pearch. The stock pearch limits camber to around -3.5 max. I don’t think that any camber plates that has to use the stock spring pearch has any advantage over another. Well, maybe solid bearing to something like K-mac but otherwise no advantage of one over another.
Another good think about the adjustable plate is if you get hit in the front and after going on the frame machine the towers are still not perfect you can adjust the camber plate to offset the moved strut towers. Don’t ask how I know about this.
