frs oversteer in brz mechanical? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Is there a mechanical difference between the brz and frs that give the frs more oversteer? I feel like I'm noticing a falloff on the oversteer in my brz and was wondering if it was a new mod I would need or is that some kind of computer change to get the same feel in my brz.

Pretty simple,

FR-S is softer in the front and stiffer in the back making the tail come out easier, BRZ is more equally sprung lending it to very slight initial understeer.

heavier rear sway bar (or adjustable)may be easiest way to increase oversteer on brz

Like mentioned its the spring rates. I have RCE yellows and love them. Still allows the rear to step out when wanted but in a more neutral fashion if that makes sense.

FRS rear springs. Ran them in my BRZ up until last week, loved it.
