I've done some research, but haven't found an answer to my question.

I currently have an X with stock 17's and 215/55 tires. I am installing a mild drop (Coupe fronts and Sedan Sport rears) which will give me approximately 1" in the front and .5" in the rear. In the near future I will be installing Coupe 18's with 235/45 tires all around. Not sure when this will happen because the tires I want are on a nationwide backorder.

My question is around when to get an alignment. I've already installed the rear springs and plan to order and install the fronts within a week. Since I don't know when the new wheels/tires will be ready, should I go ahead and get an alignment now or wait until the new wheels are installed? I haven't been able to find a clear cut answer on whether or not the different width and offset of the Coupe 18's will throw off my specs compared to the stock 17's. I'm trying to avoid destroying my current tires so I can put them up for sale. I'd also rather not get two alignments if I can help it. Any ideas?
