Have not tried radials yet almost bought some this year .
On the bars I have them in the bottom hole just touching on drivers side 2 flats on other side .
I have my car very tight on the shocks .
Afco DAs in front full tight on ext. and went from slant 6 T-bars to 318 bars.
Really think I need to go to a even heavier bar to be honest .
On rear I have the ext. pretty tight to slow separation.
But we are still working on it and next year should get it dialed in pretty quick .
