What do you estimate the final total weight will be?
Great question. I have one data point so far to use in making a weight guesstimate. When I took the car to San Diego in January for the transaxle work, my friend has a nice hoist mounted scale and our curiosity caused us to break it out as we could weigh the car without taking it off the trailer. The chassis weighed 1,200 lbs. at that time without having engine or transaxle in it. What we weighed was the full rolling chassis including suspension, coil overs, rims, tires, rotors, R&P, sway bars, gas tank, radiator, windshield, hinged/latched door frames, and front clip framework. We were all pleasantly surprised as our guesses were at least 400 lbs. higher than that prior to the weighing.
So to extrapolate from that, the complete car could come in at 2,500 lbs. if I'm miserly on interior, etc. I'm guessing it's more likely to be 2,700 lbs. or so given its a street car and I'm more inclined to add comforts like leather interior and good sound deadening in. Even if it comes in at 2,700 lbs. that's really good for a coupe of this size that has A/C in it.
