1st of all, those are not 25" wheels in that photochop. may 20" or as much as 22".
It would be possible is you never planned to drive it. 25" wheels would be too heavy for the Celica to move, not to mention the brakes would never hold up, plus the stock drive shaft would snap in half. The fuel nossle would have to be relocated since wheels would rub on the nossle if you slammed the rear that low. And the front fenders would have to be enlarged in order to turn the wheels...plus the bumper would have to be chopped and you'd probably would loose the side marker.
wow. a lot of misinformation here. let me explain.
first, i have no clue what makes you think the fuel nozzle would rub on the wheel. i don't know where it is, but i know it's not at the top of the wheel well, which is the only place the wheels/tires will rub except the inside of the quarter panel. the wheels can only be so wide before they start to rub on suspension parts.
next, the celica doesn't have the driveshaft, and the axles would not break as soon as he starting moving. if he managed to get enough power in the car to launch with 25" wheels, i could see a problem there.
then, even if he did have to shorten up the front bumper, the Sidemarkers
are way too far forward to be lost to the cause, unless you just don't like how close they are to the edge of the bumper. i don't think that the bumper would have to be trimmed much at all, if any.
i don't mean to sound like a jerk, but i wanted to prevent anyone from thinking wrong things about something like this.
