I race mine a few times a year. My local track is pretty relaxed on the roll bar rule for convertibles. I have a "style bar" but that will be gone if I ever do go with a roll bar.
My times aren't that fast since I can't 60' worth a flip with this stock rear and I only have bolt ons. But I have a complete DSS 9" set up in the garage waiting to go in. Only reason it isn't in yet is because I'm swapping the gears to 4.57s. That should get this fat girl out of the hole.
Here is a video of my car running.
