Interesting. My code reader displays the yaw sensor output live and it seemed ok (although sebring people weren't happy with my testing i bet). Steering angle showed -25 degrees when straight so that helped with the code error pointing to a specific issue. Helped by the fact i threw this clockspring in after it failed on srs testing in another car. I'm going to watch it tomorrow and if its annoying I'm pulling the fuse. Right now im just treating it like a time trial and doing 4 laps then coming in and restarting and doing 4 more ha

Full disclosure the alignment is also a bit more aggressive which will make up some of that improvement. The biggest difference is how the SRCs are handling the rough ass sebring surface. These bounce, a lot, but they don't violently toss the car a foot sideways like the eibachs did. T17 here is a lot better with the SRCs. My corner speeds in t10 and t13 are also multiple mph faster but most of the corner speeds seem similar. The SRCs are pushing more even with more toe out up front. Trying to adjust with tire pressure for that.

End of the day though, they are faster.

Oh also im using them with teins edfc active pro setup that ive now spent a bit of time fine tuning..

Dave, do you pedal dance?

Tracbox to do so, but yes.

Yeah, sounds like clockspring... My steering angle was reading normally when we checked it in the garage. If you have same pads front/rear probably better off to just yank the fuse. Crazily asymmetrically locking front brakes bad!

I ask because I get where Mike was coming from. Unless I'm missing some key part of the system, this has nothing to do with the yaw gyro or steering wheel sensor. Do you or @Opie have any spare ABS units to swap in for testing?

I doubt it, we never need them so they go to the scrap yard. I need to fix pad bias now ha

Oh, because abs fuse?

Yeah.. not the fronts lock earlier because of the pad.. running ds1.11 up front and only ds2500 in the back.

If I was in town (instead of at MSR Houston with the Austin86 & Houston86 groups) I would use the techstream to recalibrate the steering angle sensor and see if that improved anything. Definitely sounds TCS related. My car was hyperactive on track at one point last year because mine hadn't been recalibrated.

Were you also in PD mode? (full vsc disable, test mode, whatever we're calling it)

Yep

Oh yeah.. to reconfirm that the left front is the worst.. the LF tire is flat spotted almost to the cords.. the front right is just slightly flat spotted. I ended up just switching the left front and the vibration from the flat spot went away about 98%...
