[Twinz]

Do you have any video of this happening where we can also see your steering inputs?

I just did my first autocross with the FRS prepped for CS and found that my first guess at sways and alignment produced considerably more understeer than stock. I was able to play on a traction circle and drive another twin for comparison and the car itself (my car) understeers.

That being said, I did not experience any shudder, so I'm wondering about your steering angle when this is happening to you. I suspect wrenching on the wheel while the car is understeering (as apposed to just lifting to tighten your line) might cause hop, but I'm unsure.

BTW, for any setup gurus, this understeers now:

TRD springs and sways

Koni shocks

Front:-1.3, 1/16" toe out

Rear: -1.8, 1/16" toe in

I am considering either going back to stock bars front and rear, or maybe even just back to stock bar front. (leave TRD sway in the back)
