Reducing weight on topside of car

[stevestratton]

Building out a 1990 Miata for STL and want your opinions on spending $$$$ to reduce the topside weight on the car. In particular, windows, hood and trunk? Already working on the motor, need to buy an ECU management system and wondering if I should upgrade the current ITA suspension or spend the money to, in effect, make some adjustment to the CG???
Thanks Steve

There is a fiberglass top available out there in the world.

Thanks, I'll start looking there for weight savings.

I've seen a few carbon fiber tops floating around out there for about $1000 (used). weigh under 10lbs.

never looked at the rules for a top, but I know hood and trunklids are legal for composites..

Carbon Roofs are not permitted in super touring.

Yes, it can't be carbon. I know tha Miata's are using a replica hardtop that's way lighter than the OE as they're a single lay up of fiberglas and kevlar and they don't have all that stuff for a nice inside padding or mounts that the oe top has.
