I am looking to buy a light flywheel for my 87 RX-7. My car is not a turbo, and I do not know the exact model because it has no stickers on it to tell what model it is. But what is on the car is the 5 lug rims, sport tuned suspension, and 4 piston calipers in the front. If that helps you decide on what model I have then so be it. Thanks.
