There are a ton of upgrades you can do to the Mazda RX-7 from body kits, exhaust, suspension, wheels and tires, etc. I could sit here and list every single modification you can do to a RX-7, but I hope this link to a parts website will do. Otherwise this page would be extremely long and take more time than I had to make this website. So I'm sorry if this page is a little boring. Car ID Auto Parts
