You shouldn't because the wheels have nothing to do with the geometry of your suspension. For example most cars have camber, caster, and toe adjustments.

Camber
Camber is the angle of the wheel, measured in degrees, when viewed from the front of the vehicle. If the top of the wheel is leaning out from the center of the car, then the camber is positive ,if it's leaning in, then the camber is negative. If the camber is out of adjustment, it will cause tire wear on one side of the tire's tread. If the camber is too far negative, for instance, then the tire will wear on the inside of the tread.

Camber
If the camber is different from side to side it can cause a pulling problem. The vehicle will pull to the side with the more positive camber. On many front-wheel-drive vehicles, camber is not adjustable. If the camber is out on these cars, it indicates that something is worn or bent, possibly from an accident and must be repaired or replaced.

Caster
When you turn the steering wheel, the front wheels respond by turning on a pivot attached to the suspension system. Caster is the angle of this steering pivot, measured in degrees, when viewed from the side of the vehicle. If the top of the pivot is leaning toward the rear of the car, then the caster is positive, if it is leaning toward the front, it is negative. If the caster is out of adjustment, it can cause problems in straight line tracking. If the caster is different from side to side, the vehicle will pull to the side with the less positive caster. If the caster is equal but too negative, the steering will be light and the vehicle will wander and be difficult to keep in a straight line. If the caster is equal but too positive, the steering will be heavy and the steering wheel may kick when you hit a bump. Caster has little affect on tire wear.

The best way to visualize caster is to picture a shopping cart caster. The pivot of this type of caster, while not at an angle, intersects the ground ahead of the wheel contact patch. When the wheel is behind the pivot at the point where it contacts the ground, it is in positive caster. Picture yourself trying to push the cart and keep the wheel ahead of the pivot. The wheel will continually try to turn from straight ahead. That is what happens when a car has the caster set too far negative. Like camber, on many front-wheel-drive vehicles, caster is not adjustable. If the caster is out on these cars, it indicates that something is worn or bent, possibly from an accident, and must be repaired or replaced.

Toe-in
The toe measurement is the difference in the distance between the front of the tires and the back of the tires. It is measured in fractions of an inch in the US and is usually set close to zero which means that the wheels are parallel with each other. Toe-in means that the fronts of the tires are closer to each other than the rears. Toe-out is just the opposite. An incorrect toe-in will cause rapid tire wear to both tires equally.

If the sharp edges of the tread sections are pointing to the center of the car, then there is too much toe-in. If they are pointed to the outside of the car then there is too much toe-out. Toe is always adjustable on the front wheels and on some cars, is also adjustable for the rear wheels

You wheels have nothing to do with any of this. Hope it helps.

thanks for all the info, i was asking because the mechanic was like if you put bigger wheels and don't get a wheel alignment then you ruin a lot of parts of your car like the hub bearings and etc so i wanted to make sure..

nah once you get the wheels balanced your fine. removing them does nothing to the suspension.

now every time your remove your struts, you'll need an alignment.

i do hear that it is recommended after putting new wheels on since it will be little out of spec. donno about hub bearing, but more concerned about wearing out expensive tires on larger wheels.. (not that we can correct this 100% on lowered car without the adjustable set..)

Hey Adam you should have no issue, unless you need to change the alignment specs to get those massive twinkies stuffed into those wheel wells

they should fit perfect because i did a lot of work under that wheel well, i shaved almost everything that was in the way of the wheel and the wheel well plastics get removed, the only thing i am worried about is when i hit dips it gonna rub, i will get it all settled tough

You should at least check alignment after suspension mod, but wheels ?
