When putting the right foot down in 2nd and 3rd gear steering wheel really tugs hard nomally to the left,feels like wheel spin,car is 04STI,is this normal,is it the front diff trying to gain grip.had03ppp before and didnt do this.Notthat bothered but do they all do this

 

My 05 STi pulls slightly to the left.Think I've got used to it, but when I had my 1000 mile service yesterday the mechanic who test drove it noticed it, and recommended getting it Optiflex'ed (fancy wheel alignment I think).So it`s going in to be done in a couple of weeks.(hopefully under the warranty-surely a car should go straight when it`s new)

 

Mine only tugs on very hard acceleration,doesnt pull to the left in normal driving
