its has better brakes, i dont know the difference in suspension on the new sti's and wrx. wheels/tires?
The transmission alone as stated is worth 6-7 grand over the ****ty wrx trans. When you upgrade your sti you can sell the sti parts. when you upgrade the wrx, noone wants the stock **** (less demand)
we did stage 2 on my boys 2012 sti and holy **** the car is fast. ive never rode in a stage 2 wrx that i thought was fast.
edit- i guess if you want to leave it stock. then get a wrx.
