Yes these can be dailyed on, just need to be cautious in the rain on rears. I ran no fsb and did not notice a handling difference from when it was on, but i had shocks/struts and springs which will help. Due to the staggered widths from front to back you will have understeer but with good suspension setup it can help compensate. For most people understeer isnt an issue due to straight line performance and not carrying about handling.
