Are those gold coloured bevel gears on your front/rear diffs lightweight solid titanium alloy units or just titanium nitride coated steel for ware resistance like drill bits? I may have to investigate whether they will fit my hot bodies diffs or if anyone else makes ones that do if they are solid titanium and offer a decent weight saving.

Thats a good idea with the rub strips, my buggy is much stiffer since my on-road conversion so even with the reduced ride hight im not planning on grounding out much, but like yours my surface isn't the best (thats why we convert buggies rather than just run serpents right) and I'm sure it will get the occasional scratch, I'm now thinking of gluing 2mm titanium welding rods that can be found fairly cheaply on Ebay to the underside, one down the middle and one down each side which should give good protection to the bottom for very little weight gain and also give a cool firework show like the F1 cars do if it grounds out.

I'm digging all the carbon, you should consider making carbon battery trays too, very lightweight and lower CoG too as they sit directly on the chassis.
