The overall layout looks really good as well.
I am very worried about that front end though. Having the steering axis so far from the centre of the contact patch will make it pull hard right under brakes - like really hard.
I have done some quick math on this for you, and I estimate that under brakes you will have to apply 70kg of extra force on your right hand than on your left to stop it turning. I would look at getting that steering axis as close as you can to centred in the tyre, but that is pretty difficult with kart wheels unless you go to a more conventional setup. The numbers I used for this are attached as an image.
If it were me I would also move that front wheel back towards the engine to shorten the whole lot up - but that is pretty unfounded, really just my musings about what makes a sidecar fast around a short track.
