Turn Six Sway Bars

[Mr.Woof's72z]

Anyone heard or have any experience with them? I can't find any info on them to save my life, and I've checked google, MSN, yahoo, AV, all the major search engines. The only things I've come up with is a Spitfire Sway Bar and an RX7 sway bar F/S on ebay. When I bought my Z it included a box that said Turn Six Sway Bars on it, along with a new yellow rear sway bar already installed. Trying to see if these were/are any good or if it should be taken out and replaced. It seems to really help with body roll, though my only other experience driving another Z other than mine was 3-4 years ago in a 280Z, I have a 240Z...Any help would be greatly appreciated!
