The problem is the top cap is bigger than the V2s. I only had to shave a little off the front B4.1 tower to prevent the Ghea collars from rubbing and nothing had to be done on the B44.1 towers. To do the same for these new shocks will require more material to be removed and/or the use of spacers. Most (if not all) the pictures I've seen of BBs on pro cars show mods to the tower(s). That tells me there is something they don't like about using the spacers. Either way, I'll wait and see what the masses experience.
