Hi all,
I've posted this issue in a few other places and haven't gotten many replies - figured I'd post it here since this is a forum dedicated to the S197 platform. I have a 2012 GT 6-speed with 21K miles and a few mods - Airaid CAI, Bama 93 tune, LTH over-axle pipes, Roush axle-back exhaust, Ford Performance sway bars, Koni yellow adjustable struts and shocks, H&R Super Sport springs, J&M caster/camber plates, Stoptech Cryo rotors and G-loc R8 pads all the way around, and Nitto 555 G2s (stock size). I did a Track Night in America event at Road Atlanta at the end of last month, and during the last session, I got the "Service Advancetrac" warning and all the dash lights associated with the error. After some forum searching and digging I found out that the RR wheel speed sensor wire had gotten against the exhaust and melted, causing the error to pop up on hard RH turns. I had the car on my friend's lift the other day and we cut out the damaged portion and spliced the wires and tucked them up out of the way. The REAL issue I'm having is that since I got the warning during my session and the wires got burned, my car feels like the e-brake is on all the time or the brakes are dragging...except they're not. I've spent a few drives now closely monitoring the brakes and none are getting hotter than the others and I don't have any of the other symptoms of a dragging brake. I've got an email in to Bama so I can try to send them a datalog to rule out any engine issues, and the only other thing I can think that might be wrong is something in the clutch or that the ABS module itself is damaged. I know people have had issues where the clutch won't fully disengage, and that could be this issue, but I don't have the RPM increase with no speed increase that comes with a slipping clutch. I'm sort of at a loss here and very tired of my car feeling like it's pulling a trailer. Has anyone else had a similar issue? If you need any other info I'll be happy to provide it. FYI, I did do brakes before the TNiA event and couldn't push the rear caliper pistons in but it wound up being a tool issue - I couldn't get enough pressure to push inward on the piston. It would turn but not retract. At my friend's house the other day I was able to use the correct tool (thanks Advance Auto Parts) and pushed the pistons in with no problems. Everything brake-wise seems to function as it should.
