If you really want weight reduction remove the cast iron bars under the battery. 21,2 kg. Replace them with aluminum ones. 2,96 kg
In the review you mentioned the stiffness of the ride. Remove the heavy swaybars.
Remove the thick steel plate under the front and the useless one on the rear. Replace them with polypropylene or styropor.
Remove the heavy aluminum wheels. Replace them with the lighter steel ones. I can help you out with these
This all will give you a weight reduction of at least 45 kg Which other car can get a 10 % weight reduction so easy?!
You'll feel the weight reduction when accellerating.
If you want more km out of a charge allign your wheels. Look at your left rear tire. It has all the signs of a really bad allignment. On this forum you can read how to allign your T yourself. #Trackrite
And when done, put the front fenders back they really keep you from getting dirty
