The kits are made out of basalt fiber which is made from lava rock. It is very light and very strong with a high strength-to-weight ratio. Larte’s special bumper weights less than 30 pounds. The stuff is also used in bulletproof vests, although, don’t get any ideas about testing that feature with your Tesla.
It’s also resistant to things like moisture, salt solutions, alkali and acids so that it will better stand up to the rigors of daily use. Larte designed the kit to not just look good, but improve the car with better materials and an overall reduction in the vehicle’s weight.
