I've got a set of the Williamsville risers. I waited a long time to get them, as they are machined one at a time. None of this CNC, turn the machine on, come back later and and clean it up for shipment on these risers, no, no. They are incredibly well made. As are my MPH risers on my N'Corsa.
However, they were more expensive than my MPH risers with less rise, took longer to get and have much less adjustment capability.
Would I get rid of either? Absolutely not. I appreciate all the engineering and value of both. However, if I were to set up another V11variant with a riser mod (which I will), I will again go for the MPH. So, if you aren't happy with your MPH parts, please let me know. I am looking for a ste, I mean deal!!!
