10 things you need to know
 

apologize if this has been discusses before but
is there a "BIG' difference with these?

10. Its Suspension Setup Is Different From the Subaru BRZ
The FR-S has lower spring rates than Subaru's BRZ, but its dampers are stiffer. The change primarily represents the tuning strategies of each company and personal preferences of the development engineers. This and the styling differences are the only substantial changes between the cars.
Scion will, at a minimum, offer aftermarket lowering springs and stabilizer bars for the FR-S as well as several alloy wheel options

NO, its subtle, you will probably only notice if you drive hard through turns or try to get the car loose. And the reviews are mixed as to which car has a better set up. They are different, neither seems to be better. The FR-S will drift better, the BRZ supposedly was designed for stability.

Once you start putting aftermarket suspension parts the difference no longer matters.

Front suspension of BRZ is different than FRS. Reason is most of BRZ owner gonna be previous Subie owner. They're used to understeering vs Toyota have made several RWD cars, so they finished it w lil bit of oversteer
