yea, i also hear that the WRX got some turbo lagg.
WRX STI is a rally car. the car is made for corners and good handling. In rally races most of the time the rear wheel drive cars are behind the four wheel drives. I may be wrong but i think when they made WRX or wrx STI they mostly focused on getting low numbers on 0-60 or 0-120 since not often you'll go passed those speeds in rallys. I may be wrong, just putting in my 2 cents
