Get the fixed Ireland Engineering plates.
You'll find the extra camber really improves the turn in. Some minor impact on edge wear.
I've had mine (adjustable) for years - love them. Only thing I would do different is get the fixed ones as I have never adjusted mine once in.
Be sure to swap in the 3mm front spring pads at the same time to offset the impact of the added thickness of the plate.
