Celica Forums General Discussion General Car pulling when accelerating

I have a 02 GTS with Eibach Springs, and 18" wheels and tires. It seems only when accelerating, like passing someone or just down the highway my car seems to pull to the left a bit. While traveling in a straight line, if I let go of the steering wheel the car stays straight so I don't think the alignment is off, however it hasn't been aligned recently. Since it only happens when accelerating I thought maybe it was because of the FWD. I used to own a 240sx which was RWD, so maybe I am not used to it, but it seems a little much, and sometimes is awkward, especially when passing. Its like the steering just breaks just a bit then its ok. Is this how all Celicas are or should I visit an alignment shop? I put on the springs and wheels right after I bought the car and I don't remember if it did it with factory wheels, springs.

one word - alignment
