Hell yeah man, looks great! I dig the big pink Hobbywing sticker - I have one of those, but I don’t think it would look right on the gold car.
Regarding weight - I am pretty sure that the ROAR limits are minimum limits, not maximum limits; but if you want to save weight, well, here’s what I’d do - prioritize things that are going to cut weight while increasing performance in some way other than ”just by saving weight”.
For example - a TI turnbuckle kit will not only save weight, but it’ll make the car handle a little better because your steering and roll linkages will be stiffer. FT carbon arms will save a little weight, but more than anything they’ll pull a bunch of slop out of the car’s hinges. You could also try @bill_delong’s 4wd trick of running 2wd wheels and tires up front - that should help the car accelerate quite a bit faster due to reducing spinning mass. You’re on the right track with a lighter body - that saved nearly an ounce on my car, if I remember correctly, and by cutting so much weight off of the highest part of the car, you’ve lowered your CG, which should get your CG closer to the roll center, which should help handling a little.
