I believe those are the GM bars that they are selling. Being that the 30mm bar is discountinued (don't know about the 26mm), it will be very hard to track one down until an aftermarket company starts making them.
I was also looking for a 30mm front bar just a few weeks ago and I couldn't find one, so I decided to bite the bullet and try VBP's 32mm front sway bar. I am using their swaybars and springs. I thought I would have a problem with understeer, but it was suprisingly neutral this past Sunday at an autocross event.
