Last I read on their forum was they were waiting for Ford Racing to release an updated version. The factory steering rack has been on backorder for months. Seems they will be available June 23rd(today).

"We have to have the updated programming for the steering rack before any of these events, as I'm tired of seeing the same nagging computer errors and steering wheel feedback. Now that we're confident this programming is SCCA legal I'm going to get it done. We will be pulling the rack out of the car this week to send it to Ford Racing, as the replacement $1000+ 2011 GT racks is on national back-order. Apparently there's a 3-4 month build date window where all of the early 2011 GTs are having similar "issues". Ford is not doing a recall yet, but probably will "eventually". If you are seeing this type of steering shudder CALL YOUR FORD DEALER and demand a recall/TSB. If you don't want to wait, call Ford Racing in Detroit. All of the World Challenge and GRAND AM Mustang's run this update programming, and it supposedly fixes the steering feedback loop shudder and related Traction Control system faults. We'll find out and report back soon!"

"The one problem that was missing was... the traction control faults and steering feedback shudder. WTF? This is a mystery but I have noticed that the more wheel spin we see the more problematic the steering is and the more faults we trigger. With 345mm rear A6s and a fresh LSD out back there was dramatically less wheel spin. This is good, because both the OEM replacement and the FRPP race re-programmed steering racks (M-3200-EPAS, $1249) are on national back-order until June 23rd. We found one in the country after calling dozens of places, and they were saving it as a spare for their GRAND AM race team. Wouldn't sell it to us for any amount of money. So... we cross our fingers and hope this steering rack and traction control fault issues take a hiatus. :/"
