Handling with a 15" rim?

[Turbo Noob]

I'm planning on a QA1 coilover setup in the relatively near future, but I still want to run the stock T-type rims. Are there any tires out there that will fit my stock rims and give me some sort of decent handling, or is my only option upgrading to larger rims?

The problem is that with 15's there is just so much sidewall. That much height allows the tire to squirm around a fair bit. While they can be made to work pretty good, the lower aspect ratios of even a 16 are noticeable. Not to mention that once one gets some big brakes, the 15s are no longer even an option.
