1/3 scale 125cc V10 hybrid rc car, part 7

I've had a bit more time than expected since the last update. Main job has been making the front brake calipers. They have been a bit of a pain but it's all working now. they have 16mm pistons and cut down cycle Kevlar pads. Managed to find some 6" kart tyres as I hate the existing 5" wheels and tyres. Made a split rim for the front to check if they're going to be ok, and I'm happy with them, and the wheel design. Just got to decide what to do with the ultra-wide rears.
