i want to know if a wheel 16x7.5 will fit in a dropped xa. also i want to know what springs offer the lower drop with the best performance.

thanx

Tanabe DF210, Goldline, HKS, offer a 2 inch drop which is the lowest possible drop on springs without bottoming out the factory struts.

i know the variety of springs and their drop. but i want to know what spring would be better for performace

also anyone know if 16x7.5 offset42 will fit in a dropped xa???

What type of performance?

It will fit, though there is a possibility that it might rub at full lock given that 16" rarely come in 7.5" w. You can read the wheel faq for more fitments and user experiences :D
