A. Yes, they do make bearing dust caps for shpereical bearings. And, in my opinion, if they went this route it will be fully tunable to EVERYONE's very diffrent needs, and replacing the bearing is 100 times easier with that setup then a ball joint. Yes, the bearing will wear slightly faster. Yes, you can get a boot to slow that down. Yes, they cost a tad more. But I feel all the pros of the bearing highly outweigh the cons.
B. Thank god you guys are going that route now. Just make sure sway bars can hook up to it and I will be happy as hell if you do the ends similar to how it's shown above. When will you be taking pre-orders?
