I plan on making custom bars for my car this off season as well.
I know krazik had done some sort of speedway rear bar on his car with straight arms and don't think he had clearance issues.
If all goes to plan on my car I will be using chrome-alloy roll cage type tubing and running a full custom setup.
if so I will have pics in my build thread that has been neglected for the last few months.

 

Any pictures of these sway bars? I am looking a set myself... I was considering the Moddiction adjustable sway but they seem to be sold out... I am not clear what's the hold up on new batch. It seems there are enough people wanting them.
