the harsh ride youre experiencing with the stock shocks are probably because the shocks are shot and are bottoming out. similar to what would happen with HDs as well
I can't remember if this guy had the HDs now or the sports. I'll have to check and see if I still got his email and maybe I can see what springs he was running with them. My stock shocks are pretty much on their way out after 36,000 miles of track, autox and street driving through NJ/NY and Canada
