I read the Motor Trend magazine comparison in the dentist's office. As I recall for his test Randy was a little quicker in the BRZ than in the FRS due to more oversteer with the FRS. As I recall one of two has stiffer springs according to early information. Anyone recall which one? Balance can be changed for autocross with shock tuning or the F or R bar change rule now in effect.
Found the "answer" in Car and Driver. It looks like the BRZ would be the better starting point for a Stock class car since the current anti roll bar allowances (front or rear) and shock tuning should allow tuning out any understeer.
"At the limit, you’ll find the key difference between the Subaru and the Scion. Go screaming into a turn or hop on the gas too early exiting one, and the Subaru simply understeers—perhaps for the benefit of drivers familiar with the brand’s all-wheel-drive products. The Scion uses softer springs and stiffer shocks, and it has a sensitivity to driver inputs that makes it feel alive. Too much or too little throttle upsets the Scion’s balance, sending the car into an easily controlled drift. Its behavior reminds us of the dearly departed first-generation Honda S2000. It’s not impossible to get the Subaru to oversteer—deliberately timed and moderated inputs will coax the tail out—it’s just not going to catch you by surprise. In either car, though, the transition from cornering to drifting is gradual, and the low curb weight—about 2800 pounds—helps make it easy to rein in a slide before you tailwhip your neighbor’s mailbox."
