I don't think stripping the car is good unless it's just for track use. On the road it will be very noisy. I sometimes take the back seats out but they don't weight that much. Far better getting decent brakes and tyres and a performance air filter element as well as upgrading the engine mountings. Over the past three and a half years I've replaced the dogbone bush for a Powerflex one, K Tec engine mountings, green cotton air filter, braided brake lines , Ferodo DS2500 pads all round, Brembo HC front discs, left the calipers as standard, Toyo R1-R tyres, Scorpion cat back stainless exhaust. That's turned it into a really good track car that I can use on the road as well. The interior is complete so it's comfortable on the road. The Aircon works so staying in. Everything works as it should so I can't see the point in stripping it out. The whole car is in nice condition as well despite 123,000 miles. All my family say how nice a car it is.
