I don't know... usually the ride gets rougher with a lift/bigger tires. I have 919 coils & never ever hit the bump stops, but the 919s are stiff so I feel road bumps.
My suggestion is to get your ride problems sorted out first before opening a new can of worms with a lift. If you really want to lift, start with adjustable shocks (RS9000xl) & see if that helps the "crashing" issues.
