Aj,

the rear ITR bar from Jay is $249 (used to be $229 but price had to go up). Reason for mount to shock body is Jay thought existing mount to pressed steel arm was a bit flimsy if one increased the roll rate. I don't know if it only fits the Advance Design coil-overs, but they are currently out of stock and having 70 made. The shop making them apparently welds a lot of parts for Bombardier and so Jay has to wait his turn, and thus so do I. Jay says bar is adjustable and a fabulous piece. In this case I just took him at his word, eased by the fact that I as about to buy a Mugen 26 mm rear bar for $370. I will just have to wait and see.
