Couldn't get Wheel Alignment because of Modifications? Options

[DIONYZUZ]

The modification I have gotten were KYB GR-2 Struts and Tein lowering springs with 225 45 17" wheels. I tried getting a wheel alignment today but the mechanic said my suspension and wheels were "unsafe" on my celica. He went on stating that the wheel alignment machine could not align the wheels because of the lowering which affected the camber and caster. He said it requires a new bolt for the caster , but the caster is so so far off that the replacement wont even help the caster. Then he suggested to go back to OEM suspension and said "I owned a Celica GT before and those suspensions are already a sport suspension." Then he said the tires will rub and thats the main reason why there is a pull on the vehicle's steering which is what I believe is the reason it needed an alignment, but it doesn't even feel like theres rubbing. Should I get the new bolts and try another alignment? From what the mechanic said, it seems like nothing will help the alignment.

After lowering my car and doing an alignment on it the caster was pretty even at 2.1 + caster on both front wheels. Since the springs are an equal drop for the front the caster will usually end up being close to even. As long as the toe and camber are even as possible you should be smooth sailing from there.

You always want a little bit of positive toe for the front and rear of the vehicle.
