MX-5 NC too heavy? Empty space? What do you think you can achieve?

Hello you dear roadster drivers! I am actually more interested in Caterhams and Elisen, but the test drive of the MX-5 ND with 131hp was not even so bad in hindsight and now I wanted to ask how empty I would probably get a MX-5 NC. And how much weight could be reduced. Traffic fitness/TÜV should always be preserved. Passenger seat should always be preserved. It’s just about trimming the MX-5 towards Elise from the weight. Start: All unnecessary out, carpets, door panels, insulation material, floor mats. Stereo radio can stay inside (does the MX-5 work more than stereo?). Passenger seat should stay inside. What can you remove there? 1000-1050kg? Possible?Second Start: Replace the chair with lighter? Radio out, air conditioning out (heating may stay). Remove the roof, central locking on individual locks? Replace windows with lighter ones? Still with cranks or the same Nothing at all? Lighter exhaust?Third attempt: roof off, is that allowed? So that everything can be enjoyed like disc wipers and stuff.Power steering? Who the hack needs that with less than 1000kg ? Under 900kg? Possible? Would you like to hear your opinion? Did I end up in the right forum?
