My team mates and I have been using it for some time. It seems to work just as well as the fiberglass tbar but I doubt that it is exactly the same. It is not indestructable, as some would have you believe. It can get bent or tweaked so you need to check it. Fiberglass tbars (on my cars) usually break before they wear out.

I trimmed the damper tube holes because I needed to move the attachment points closer to the center to accomodate the CRC damper tubes (they are the best!). I was trying to use all the stock Yok parts so I shortened the ball cups on the tubes as short as they would go to make them fit on the stock graphite parts.

Yes I prefer tubes to discs but that is just me.
