I agree with SCRAPPYDO 100% In his review of the ST comparison.
As a prior owner of a 02 WRX, an 09 MS3. A frequent driver of every year STi. And owner of a 09 WRX with RCE Bil's / Yellows, and tune.
If I had not already owned a MS3, I would most likley be in line right now buying an ST.
I say this because of everything that was wrong with the MS3 could not outweight its awsome capabilities. The ****ty rebounding suspesions (I fixed with Bil's) The ****ty rebounding engine and transmision when all that tq came surging on like a freight (I attmpted to fix with CPE stuff). The ****ty tq control that would cut power when the steering wheel was turned more then 15 degrees leaving you feeling like you dropped anchor mid turn. And the ****ty direct injection system, most likley the cause for TONS of rods to be left in a wake of distruction.
This all scares the bejesius out of me to buy another FWD car that produces that much TQ, thats just a kissing cousin away from a MS3.
I think ill stick with my imperfect Subaru's untill I can buy a several year old C6 Z06
