Can anyone tell me what the stock wheel size and backspacing for a 95' Del Sol Si is? I would like to get another set of wheels and tires but keep the stock backspacing, width, and outside tire diameter. I am considering going an inch or two bigger on the wheel size so I can use the low profile tires for better handling. But the low profile tires maybe a little too expensive for me right now. Has anyone ever done this? How do you like it?

Thanks
