Thanks.
I changed the anti-roll bars when I moved to Supercar 3R track tires. Hotchkis adjustable front and BMR adjustable rear bars, both on middle, gave 30% more roll stiffness and matched the dynamic wheel rates to the tire grip very well. That said, grip on the street went down; I was no longer able to take my reference on-ramp at the same peak speed [by about 1-2 MPH] as the street summer tires were now becoming overworked. Grip with winter tires was noticeably down, of course.

So my recommendation is to keep the FE4 bars unless your intent is lap times with sticky tires, street/wet grip be damned.
